Yes, that's a burden that electric vehicles will probably have forever. But if some day we develop batteries with more energy density than liquid fuels, they might make up for the weight.
@@aeroengguy448 That is great but that's not what I'm talking about. You have to be very conservative on your battery so you have enough power available when doing a normal landing.

I'm really curious to see what fault tolerance you can work into the Sevcon Gen4, typically they just open the main contactor and drop all power when they fault out which could be sketchy if don't have enough elevation to autorotate. LG chem cells are a great choice for this, really looking forward to future development of electric craft like this!
Matt here. That is one of the concerns I had with using this controller. You are somewhat limited with how you want the controller to handle a fault situation. However we did already test it in an auto from about 4 ft and our pilot was able to successfully pull pitch quick enough and counter the tail to have a safe albeit quick landing without any damage. The problem I am actually looking at how to address is a temp fault (not requiring a key-switch reset) like an over-temp of the controller (primarily because we are spinning the motor to slow for the power we want, we are a bit too far over the controllers continuous amp rating to the motor), where it will cut back for about 0.5 second and then suddenly re-engage power. This is definitely a new experience for the pilot, where he would be making a tail correction in the auto to keep it from rotation and all of a sudden power is back and it rotates suddenly).
@@glory122 Glad to hear your auto tests have gone well. EV motor controls are still in their infancy and need projects like this to drive the requirements for aspects like fault handling. The Gen4 has a thermal cutback curve, (Figure 12) in the manual if you can dial in the thermal managment to stay under ~75-78C you'll be golden. If the high current draw is intermittent you increase the mass of the heatsink to try and get a little more thermal resistance for those flucutations. I'm sure you've looked at the options Curtis has for motor controls, they have better fault communication but I'm not sure if they are better at fault handling.
You bring up an excellent point about fault tolerance and the Sevcon Gen4. Ensuring a safe response in case of faults is indeed crucial, especially when elevation might be limited. It's encouraging to see your thoughtful consideration for the technical aspects of electric aircraft development.
I served in the Marine Corps in aviation during the Vietnam Era. Mostly helicopters where I was. Loved every minute of it being around those flying machines. No fixed-wing for me!!
3:25 25minutes hoover which means 10min actual flight time then 5hour “refuel” for another 10minutes. Remind me of the days as kid building gocarts. Get them running long enough to get a good bump of the motorized dope.
@@patrickday4206 more batteries = more weight and thus less flight time. so maybe double batteries would increase flight time by 50%, then quad batteries increase flight time a total of 75%
You should configure your battery packs in parallel so to have redundancy. If one of your packs goes wrong then the whole thing goes down because you are wired in series. Hope you have a good BMS with plenty of heat regulating mosftes and something to regulate cell balancing etc...
This is really good to see - the best innovation seems to come from small companies. I realise you're using the existing airframe but the motor and inverter would sit beautifully just below the rotor (like most turbines), benefiting from a cooling downwash and freeing up space to fit the batteries in a more aerodynamic/inboard position.
While I would put the inverter and the rest of the support package (cooling, etc) below the boom, I agree that placing the motor up there on the shaft from the belt drive pulley to the tail rotor shaft gearbox would free up valuable room immediately behind the mast line, below the boom. For those not familiar with the Emrax motors, I'll note that they have a hollow shaft which would facilitate installation coaxially over a shaft, although the bore of the Emrax 228 model is only 17 mm in diameter.
@@julian99051 separate motors are fine in a radio-controlled toy, but in an aircraft carrying a person they would be an unacceptable (to me) risk, because if high-voltage drive power fails yaw control is lost. It would be okay with sufficient redundancy and a high enough level of design and testing... but this aircraft is not constructed to anything like that level.
Yes ,any additional info on this build would be awesome . Type and brand of vcu or control unit ,type and brand of bms and details of batteries . Price point of items for conversion would be nice to for others pondering doing their own . Trying to share the info needed to keep the experimentals going! Thamks
They don't want to say (for legal reasons), but the battery modules appear to be LG Chem 16S 1P as built for the Chrysler Pacifica Hybrid van; they were available from many suppliers for a while. It shouldn't need a VCU.
Bryan, this is a big step for C-FX. Like he said, the batteries just aren't there yet. They definitely have an interesting concept for sure. Me personally, nothing beats a turbine chopper!
@@lp712 will never happen. Energy density of fuel is 33x of a junk battery. It will never supercede that and it will never beat law of thermodynamics. Just like this rhetoric of climate change delusion by leftist elitist.
This is a great project, done very well. I look forward to how it develops. Personally I always prefer series hybrid, your battery would effectively become the reserve for if the engine quits, or if you have a sudden power draw for whatever reason. Then the engine can be at its most efficient. It works for trains lol
But what's the point if we charge the batteries with fossil fuels. What has been accomplished other than making more toxic waist from battery production? I'm just not seeing the benefits of going electric. We can never hope to produce enough electricity with sun or wind, so why bother?
Nice looking helicopter, but being all electric would have its drawbacks, range would be affected by head winds, temperature, the draw of instruments, an communication equipment lad well as unforseen weather. To me I don’t think I would want to fly one all electric, I feel the same way about electric cars an trucks, people that have these electric pickups an have tried to tow a trailer ( empty or loaded ) have found out that even being able to tow the range drops significantly an chargers are hard to find an takes a long time to charge them back up if you can find a working charger or one that produced enough wattage to charge the batteries. Electric may provide you with horsepower an instant torque but not the range as of a gas or diesel engine can. Plus their very expensive right now an some have a tendency to catch fire for some reason an the fire burns hotter an is harder to put out than gas or diesel fuel. Maybe in time they can overcome those problems though at my age I may not live to see it. I do wish them luck on their project an that they can get it working.
Thalass, gasoline engine plus generator plus fuel added to the already existing batteries and motors would make it so heavy it would get off the ground.
Wow even in prototype i am loving it .....what a compact setup so smooth...... With more flying time in future i definitely love this concept 😍....... So simple and it's amazing...... Minor changes can do wonders keep it up 👌👌
That’s such an exciting prototype! Obviously the challenge is to extend that runtime and range.. as the battery technology catches up these kinds of aircraft will be such a cool and novel mode of transport for the people who are lucky enough to be involved!
The entire chopper chassis would probably have to be completely remade to encorporate all of the added weight and packaging :/ Maybe a fundraiser model with the size of a robinson or a little bird? But it is a vital step for their developement as a company!
Solid state batteries are difficult to get right but a few companies have made some pretty good progress. Those batteries would really unlock the potential here. High capacity, light, and safe.
@@illuminatedperspectives2894 the first electric cars had a thousand pounds of lead acid batteries and had a range of 20 miles. Look how far we've come from that, and remember that nearly ALL the massive ev advancement has been in just the last 10 years. This is a first gen, essentially prototype electric helicopter. Imagine in just 5 years how much more advanced they will be! Now imagine 10 years!
Very cool! I'd love to be able to play with this. What's the torque percentage indication at hover out of ground effect on a Mosquito and what is max? 40 kW and 2750 rpm gives 138,9 Nm of motor torque. Sounds like you need lower kv motor to keep running it if you're maxing out the current limit of the controller now.
I would take this helicopter any time over all those 4 and tons of motors electric manned drones that are tend to crash one day sooner or later if one motor goes down. this helicopter with conventional system (but electric power) will still do auto gyro landing if motor goes out. the safest and best, most efficient way to fly is helicopter and now we have electric wow. Wish I had money or wish you were hiring, i would love to come and work with you guys :)
@@jimj2683 cheaper and easier, thats why everyone goes that way. its just scaled up drones with seats. not safe at all. one rotor has issues and you crash. imagine having a life on board. With this helicopter, it will do auto gyro landing, and if they provide a parachute for whole system that would be even double safe. I would take helicopters any time with eyes closed over those new drones coming out with so much promises but no safety features at all.
Not really. Solid state will only double the flight time. So it goes from 20 to 40 minutes hover time. But then you have to factor in some margins and you are left with maybe 30 minutes or less depending on usage. That is still useless. A gas helicopter can fly for several hours. Hydrogen fuel cells will be somewhere in between.
@@Rose.Of.Hizaki 25 minutes is a joke. Thats just hovering let alone going 60mph. 😂😂 This forced green scam is nothing but a scam for carbon credits to avoid taxes.
Yes! Please do a follow up with these guys as they continue to develop. 25 mins in the hover is one thing but do they have numbers for actual point to point which is a bit more efficient. Even 25 mins isn't so bad as a point to point hopper if that suits your mission. Half hour charging is fine because you would never fully drain the battery anyway.
I doubt it gets 5 minutes with a pilot. they even had to edit the seconds long flight and then show a jet powered one. electric airplanes can barely get 20 minutes.
@@thecloneguyz The drive system is the same arrangement as they use with a piston engine. the belt drive. An electric motor has very low spinning mass and no compression so it may not even be needed to disengage the motor. Or the belt drive has an auto clutch that lets the rotor spin when the motor stops providing power.
@@frankyflowers The KW draw in the hover and battery capacity seems about right for 20-25 in hover. I assume that's ground effect hover though. They look like Nissan Leaf batteries. Other electric converted helicopters (there is/was a R22 testbed) also got around 20 minutes. They did mention that this is in very early flight test stage so I wouldn't expect them to go far just yet. The Pipistrel Electro 2 seat fixed wing trainer gets one hour flight time plus reserves.
I'd like to know whether they think a separate motor for the tail rotor would be a good idea, particularly if they were clean-sheet designing an electric-only model. How much room for optimization do they think electric motors could allow, if they completely drop provisioning for a traditional drive-train?
Matt here. It's an idea we have discussed. We would be able to cut out some of the losses associated with the splitter gearbox for the tail/main rotor, the driveshaft, and tail gearbox. Main thing holding us back is that this would need it's own motor controller, some sort of redundant battery, and rotary encoders for the pedals. You really really don't want to lose tail rotor authority in a helicopter, so it would need a lot of testing. Currently we are testing the electric power-plant before we start thinking about any changes to our drive-line, which is well proven.
Those tiny model helicopters always have a large gear covering the whole underside of the cabin. I figured that this is the lowest friction solution to get some torque onto the shaft. Hidden from the downwash. Does not obstruct the view. Redundant motors: one in the front, one in the back.
@@caseysingletary9260 It won't cost less than a piston engine helicopter, it just can't because of the scale economy. Want proof of this claim? Just think about the Pipistrel, the electric version cost more the the piston one. Not the other way around.
@@limamikeaviation6200 if this kit ever does make it to market, it will not cost nearly as much as a cabri or R22. End of discussion. Toss all the words out you want, that will always be a fact.
Amazing work guys!!! As an aircraft mechanic I get a little worried about not being able to measure battery temperature , or to control it yet, which would bring some concerns about a safe flight.
Yes, EAC, would love to know more about the future APU (gas motor providing power for an electric motor) option works. Especially would love to know the trade-offs on this type of configuration vs just using battery power plant. In general, would love for you to explore why this type of configuration (APU) works for cars, but why it (seems) to not work in electric aircraft. Thanks for your channel.
DEFINTELY want to see more follow up on this episode. Any guesses at public release estimates and pricing estimates would be great. Also, with the added weight of either all the batteries or a hybrid style, additional engine/generator, would this aircraft still qualify as an Ultralight according to FAA regulations? The weight was not addressed in this episode.
I suggest you and the video creator not wasting time on battery-powered heli: it is DOA just from the energy density alone. Don't wanna agree with me? The battery can improve with time? There is a limit from a chemical-thermodynamics alone- pretty much like the second law of thermodynamics ruled out any perpetual motion machine.
@@irvinewayne4086 Not the same thing but i've seen powertool batteries like the m18 Milwaukee go from 2ah 300-400 charge cycles with a 400watt output to 6ah with the same sized and weight and 3000 charge cycles and 1800watt output. There is also improvements to the inverter efficiency and weight too to be had. I remember going to job sites in the late 90s and it being a spaghetti mess of cords cause the battery powertools just weren't up to the task. Today only the air compressor and shop vac seem to be the only corded tools that are common anymore. That is only cause of increasing battery power/energy density. Idk if it will ever improve enough for a transatlantic flight but there is still much room for improvement
@@JD-yx7be yes, end of battery life, not simple dump as garbage, but some kind of refactoring battery chemistry to use in other applications, or full recycle
@@vovanikotin I know the newer LFP batteries can last over 3000 charge cycles over the older 300-500 for NCM batteries but they don't have the energy density and don't work as well in colder temperatures
I built my own batteri\y packs and they worked just fine. I am not an "engineer" but making battery packs and wiring them correctly with the BMS and other requirements is not difficult nor does it require an engineer.
This is a terrible attitude. Battery powered aircraft are no joke. A fiery death like the Siemens tragedy is the worst way to go. Please don't trivialize the risks.
Yea I would like to see the advancements they make on this. That is awesome. Hybrid is the way to go until they come up with a better battery chemistry (or release one anyway). That is so cool! I have been watching the Mosquito helicopters for years on youtube. I don't think I could ever fly one. Ill stick with FAR103 fixed wings. LoL
@@RussellD11 not only that, 12/24 volt has very little torque, and not nearly enough to drive two rotors capable of lifting a load of mass off the ground.
@@missingMBR agree, but I think if you "could" pump enough amps through at 12-24V it would have quite a bit of torque.. But agree 100% its not the safest, or best way.. Way too much resistance as well at lower volts...
@@RussellD11 sorry I got confused there. Voltage is proportional to speed. Current is proportional to torque. So you're absolutely right. You could throw enormous gauge wires at the motor and achieve the same amount of torque. But is it practical, not very, haha.
@@missingMBR they "may" also find going to AC voltage like the bigger EV cars use, may have some weight benefits, and lower temperatures..Will be interesting to see how this pans out and what they end up using.
Great to see an electric helicopter, even that it is a prototype it is a good start. Very quiet and easy to fly as far as I can see. With future improvements on battery density this will be viable. Another idea is to use a Hydrogen fuel cell. That will give a bit longer fly time.
Yes, it's just a prototype. Unfortunately, since the fundamental endurance problem is the weight of the battery, there is not much improvement likely any time soon, even with unlimited development of the aircraft.
@@brianb-p6586 🤣🤣🤣 your the exact same person that said airplanes, cars and the internet were fads. Oh you probably thought cell phones weren't going to last either 😂🤣😅
@@antr7493 No, I just acknowledge reality. A battery-electric helicopter will work well, with higher battery energy density. Even this one will work well for very short flights, once they fix the drive ratio; it is just a prototype, so that sort of change should be expected. By the way, I'm one of the people who gave your post a "thumbs up", but I've taken that away now.
I love the idea of a hybrid. Something like the Chevy Volt where the gas engine provides enough electricity by turning the generator. That's also how a diesel electric train works.
Great prototype! Are there any provisions for cooling air into the battery enclosures? Would it improve the batteries efficiency at all? Air cooling would be readily available (obviously) from the rotor.
They are doing nothing about cooling the battery modules, but they could mount them to finned aluminum plates and blow air past them, as a crude cooling system. The face of those modules which is designed to be cooled in the one that they have vertical and facing inward in the side packs; it normally sits on a liquid-cooled plate. Without proper control, they may not want more battery cooling. These cells need to be kept within a temperature range for best performance, and while too hot is a problem, too cold is a problem too.
@@brianb-p6586 Agree it's higher power per module than the Chevy Bolt donor vehicle, but it's probably still ok. It's a 3C (3 times capacity) discharge rate.
I think if they went with LiPo batteries they could reduce weight...or extend flight time a bit. I think they need more aerodynamic battery boxes as they refine the design; those boxes must create a lot of drag in forward flight, although I'm sure creating lift is eating up more of the battery energy.
They are using a type of lithium ion battery with one of highest energy density of any battery is just a different anode that is better at stacking the electrons. You might be thinking of old Nickle cadmium batter or NiCH much heavier.
I would not venture into EV aircraft rotary or fixed. The power demand of electric motors is enormous. Study the Laws of the conservation of energy with respect to electricity. So far there is no battery capable of storing enough energy for any practical application. Even EV cars of today have limited range and if the user demands more performance, the batteries will drain quicker.
@throwaway3873 It's a free country, some might say. As of the present, you have the right to make dumb purchases. if you don't already own an EV, go get one. Some people have to learn the hard way.
That’s why everyone keeps saying the word “prototype” 🤦♂️ It’s just a proof of concept machine, not a ready for market kit. CFX wants to have their electric helicopter ready so that when that Jesus-battery is finally invented, all they have to do is slap it in the Mosquito, program the controller and start selling them 🤷♂️
The main advantage of electric solution is modularity. If a new battery type or energy source appears, you simply change the batteries and that's it. I think it will start to be interesting by 1 hour endurance. At the current state maybe interesting would be changable batteries. And you can operate the heli like the RC heli models. Of course you can not to affors to fly very far away... 🙂
This whole EV crap is just that, CRAP. Cost too much and you can't go anywhere! Wake up people! Electricity is the highest cost propulsion and makes more pollution then any thing else!
Idk about the belt system. is it known to slip if you ram up motor on take off? Or what if your G force is to high when landing, causing the belt to slip due to high motor power to slow down the G force for smoother landing? since it is electric. does it have a smart system for automatic pilot? for easy take off and easy landing? Some drones have that feature.
Thats crazy Cool!! 🚁 Wild! 😮 This is great for oil companies and geographers just take it out in the field and fly the thing 😅 so amazing! Lidar and Scanning so cool!
I would love to see a follow-up. I am curious if a generator setup like the Chevy Volt or BMW i3's range extender would work well for something like this.
I live on the north fork of Long Island, (NY), work on the south fork, and driving takes 45-55mins, with one of these it’d take me less than 10 mins. Take my money!! 25 mins is more than enough to get me to work and normally work 24hr shifts so I could charge during the shift.
Go same Shaft/Parallel Circuit. It is a safer way to charge or produce needed velocity because it is running with the main current power source. For minor or emergency circuit producers, you can thermal or solar charge. But don't forget about the wind turbine charge you are producing with the blades/propellers generating. Small is always better done having nothing. 😊

Really impressive. I like the way they are pushing the tech even though so far the batteries only provide 25 minutes of flight.
25 minutes at best. y'all are cucks

THEY ARE REALLY DOING SOME GOOD STUFF THERE!
It is truly interesting... certainly! Thanks for watching!
You should configure your battery packs in parallel so to have redundancy. If one of your packs goes wrong then the whole thing goes down because you are wired in series. Hope you have a good BMS with plenty of heat regulating mosftes and something to regulate cell balancing etc...
This is really exciting to see - so much potential for development. Would love to see a follow up video.
Max 😮
Yeah, all we need to do now is add 16 times the weight in battery capacity..
I Want Do Asset Manager, Asset Take Care, Audit Purpose , Transaction Manager, Accounts And Tax Manager I Do Work for you safe And Secretly
unless they can get more out of the battery it has No potential
This is really good to see - the best innovation seems to come from small companies. I realise you're using the existing airframe but the motor and inverter would sit beautifully just below the rotor (like most turbines), benefiting from a cooling downwash and freeing up space to fit the batteries in a more aerodynamic/inboard position.
While I would put the inverter and the rest of the support package (cooling, etc) below the boom, I agree that placing the motor up there on the shaft from the belt drive pulley to the tail rotor shaft gearbox would free up valuable room immediately behind the mast line, below the boom.
For those not familiar with the Emrax motors, I'll note that they have a hollow shaft which would facilitate installation coaxially over a shaft, although the bore of the Emrax 228 model is only 17 mm in diameter.
yeah less red tape.
@@julian99051 That would be problematic for autorotation if you had an electrical failure that killed power to both motors.
@@julian99051 separate motors are fine in a radio-controlled toy, but in an aircraft carrying a person they would be an unacceptable (to me) risk, because if high-voltage drive power fails yaw control is lost. It would be okay with sufficient redundancy and a high enough level of design and testing... but this aircraft is not constructed to anything like that level.
Are you going to be redundant like magnetos for backup?
Awesome seeing technology advancing in new directions.
Yes ,any additional info on this build would be awesome . Type and brand of vcu or control unit ,type and brand of bms and details of batteries .

They don't want to say (for legal reasons), but the battery modules appear to be LG Chem 16S 1P as built for the Chrysler Pacifica Hybrid van; they were available from many suppliers for a while. It shouldn't need a VCU.

Bryan, this is a big step for C-FX. Like he said, the batteries just aren't there yet. They definitely have an interesting concept for sure. Me personally, nothing beats a turbine chopper!
They will never get there. Im in commercial aviation. Its funny idiot engineers trying but wasting money.
@@lancedooley7558 Ummmmmm yes… they definitely will … wtf are you talking about??Deal with it buddy
@@lp712 will never happen. Energy density of fuel is 33x of a junk battery. It will never supercede that and it will never beat law of thermodynamics. Just like this rhetoric of climate change delusion by leftist elitist.
This is a great project, done very well. I look forward to how it develops. Personally I always prefer series hybrid, your battery would effectively become the reserve for if the engine quits, or if you have a sudden power draw for whatever reason. Then the engine can be at its most efficient. It works for trains lol
But what's the point if we charge the batteries with fossil fuels. What has been accomplished other than making more toxic waist from battery production? I'm just not seeing the benefits of going electric. We can never hope to produce enough electricity with sun or wind, so why bother?
@@okgroomer1966 I think Thalass just gave us the point, power train redundancy in the helicopter fixes an imminent danger to life and health...
Nice looking helicopter, but being all electric would have its drawbacks, range would be affected by head winds, temperature, the draw of instruments, an communication equipment lad well as unforseen weather. To me I don’t think I would want to fly one all electric, I feel the same way about electric cars an trucks, people that have these electric pickups an have tried to tow a trailer ( empty or loaded ) have found out that even being able to tow the range drops significantly an chargers are hard to find an takes a long time to charge them back up if you can find a working charger or one that produced enough wattage to charge the batteries. Electric may provide you with horsepower an instant torque but not the range as of a gas or diesel engine can. Plus their very expensive right now an some have a tendency to catch fire for some reason an the fire burns hotter an is harder to put out than gas or diesel fuel. Maybe in time they can overcome those problems though at my age I may not live to see it. I do wish them luck on their project an that they can get it working.
Thalass, gasoline engine plus generator plus fuel added to the already existing batteries and motors would make it so heavy it would get off the ground.
25 MINUTES OF FLIGHT TIME? YOU MAY AS WELL GO BACK TO GAS ENGINES. THIS ISNT PROGRESS THIS IS GOING BACKWARDS LOL
It's amazing the sound that thing still makes! What an awesome job!. It's amazing the sound that thing still makes! What an awesome job!.
Wow even in prototype i am loving it .....what a compact setup so smooth...... With more flying time in future i definitely love this concept 😍....... So simple and it's amazing...... Minor changes can do wonders keep it up 👌👌
That’s such an exciting prototype! Obviously the challenge is to extend that runtime and range.. as the battery technology catches up these kinds of aircraft will be such a cool and novel mode of transport for the people who are lucky enough to be involved!
The entire chopper chassis would probably have to be completely remade to encorporate all of the added weight and packaging :/
Maybe a fundraiser model with the size of a robinson or a little bird?
But it is a vital step for their developement as a company!
modify a glider to an EV and design features to allow it to land vertically. helicopters are very inefficient and should be phased out IMO.
Solid state batteries are difficult to get right but a few companies have made some pretty good progress. Those batteries would really unlock the potential here. High capacity, light, and safe.
25 MINUTES OF FLIGHT TIME? YOU MAY AS WELL GO BACK TO GAS ENGINES. THIS ISNT PROGRESS THIS IS GOING BACKWARDS LOL
@@illuminatedperspectives2894 the first electric cars had a thousand pounds of lead acid batteries and had a range of 20 miles. Look how far we've come from that, and remember that nearly ALL the massive ev advancement has been in just the last 10 years. This is a first gen, essentially prototype electric helicopter. Imagine in just 5 years how much more advanced they will be! Now imagine 10 years!
Very cool! I'd love to be able to play with this. What's the torque percentage indication at hover out of ground effect on a Mosquito and what is max?
40 kW and 2750 rpm gives 138,9 Nm of motor torque. Sounds like you need lower kv motor to keep running it if you're maxing out the current limit of the controller now.
OK sure, thank you father. 🙄
I would take this helicopter any time over all those 4 and tons of motors electric manned drones that are tend to crash one day sooner or later if one motor goes down. this helicopter with conventional system (but electric power) will still do auto gyro landing if motor goes out. the safest and best, most efficient way to fly is helicopter and now we have electric wow. Wish I had money or wish you were hiring, i would love to come and work with you guys :)
Perhaps the quadcopters are cheaper to make?
Hopefully they let you test one out 🤓
@@jimj2683 cheaper and easier, thats why everyone goes that way. its just scaled up drones with seats. not safe at all. one rotor has issues and you crash. imagine having a life on board. With this helicopter, it will do auto gyro landing, and if they provide a parachute for whole system that would be even double safe. I would take helicopters any time with eyes closed over those new drones coming out with so much promises but no safety features at all.
@@dronepilot260rc i would love to, if they allow me to test it. i would even work for them in development team and test pilot :)
My exact thoughts. I don't trust anything that can't land unpowered.
I would also think that when solid state batteries show up projects like this will really take off.
I see what you did there
Not really. Solid state will only double the flight time. So it goes from 20 to 40 minutes hover time. But then you have to factor in some margins and you are left with maybe 30 minutes or less depending on usage. That is still useless. A gas helicopter can fly for several hours. Hydrogen fuel cells will be somewhere in between.
Solid state is much safer and lighter. An Aeros ANT can fly under power for more than an hour. If it had solid state then it would be even more fun
@@jimj2683 30 minutes may be fine for many uses. That could move someone 30+ miles. Rarely do helicopters travel for hours on end from point to point.
Besides what it takes to get the cobalt to build the batteries for things like this, I love it.
Weight seems to be the issue over all else. Would love to see a follow up :)
Always will be. Lol
No fat chicks!
Nothing else comes to mind? You know, with the guys head being higher than the rotors. Nothing else strikes you as a concern?
range is also an issue. 25mins is like a trip down the shops for a pint of milk and back.
@@Rose.Of.Hizaki 25 minutes is a joke. Thats just hovering let alone going 60mph. 😂😂 This forced green scam is nothing but a scam for carbon credits to avoid taxes.
Yes! Please do a follow up with these guys as they continue to develop. 25 mins in the hover is one thing but do they have numbers for actual point to point which is a bit more efficient. Even 25 mins isn't so bad as a point to point hopper if that suits your mission. Half hour charging is fine because you would never fully drain the battery anyway.
I doubt it gets 5 minutes with a pilot. they even had to edit the seconds long flight and then show a jet powered one. electric airplanes can barely get 20 minutes.
How do you auto rotate in an emergency with something that has an electric motor with no clutches to disengage the motor from the blades?
@@thecloneguyz it looks like the motor powers a belt from the motor to the rotor.
@@thecloneguyz The drive system is the same arrangement as they use with a piston engine. the belt drive. An electric motor has very low spinning mass and no compression so it may not even be needed to disengage the motor. Or the belt drive has an auto clutch that lets the rotor spin when the motor stops providing power.
@@frankyflowers The KW draw in the hover and battery capacity seems about right for 20-25 in hover. I assume that's ground effect hover though. They look like Nissan Leaf batteries. Other electric converted helicopters (there is/was a R22 testbed) also got around 20 minutes. They did mention that this is in very early flight test stage so I wouldn't expect them to go far just yet. The Pipistrel Electro 2 seat fixed wing trainer gets one hour flight time plus reserves.
I'd love to know weight limits and about a small payload version and how far down the road that might be?
I'd like to know whether they think a separate motor for the tail rotor would be a good idea, particularly if they were clean-sheet designing an electric-only model. How much room for optimization do they think electric motors could allow, if they completely drop provisioning for a traditional drive-train?
Matt here. It's an idea we have discussed. We would be able to cut out some of the losses associated with the splitter gearbox for the tail/main rotor, the driveshaft, and tail gearbox. Main thing holding us back is that this would need it's own motor controller, some sort of redundant battery, and rotary encoders for the pedals. You really really don't want to lose tail rotor authority in a helicopter, so it would need a lot of testing. Currently we are testing the electric power-plant before we start thinking about any changes to our drive-line, which is well proven.
Those tiny model helicopters always have a large gear covering the whole underside of the cabin. I figured that this is the lowest friction solution to get some torque onto the shaft. Hidden from the downwash. Does not obstruct the view. Redundant motors: one in the front, one in the back.
It sounds just like some of my radio control helicopters. All you hear is the rotor noise.
i dont comment often but this is fire
Cool in concept. Maybe someday we'll overcome that whole energy density thing.
It doesn't make sense, just buy a Cabri or R22 and you got a better helicopter today, not in 10 years.
Much better batteries are on the horizon.
LOL yeah, you know, just buy a $300,000-$400,000 helicopter instead, because you know, the average person just has that laying around 🤣
@@caseysingletary9260 It won't cost less than a piston engine helicopter, it just can't because of the scale economy. Want proof of this claim? Just think about the Pipistrel, the electric version cost more the the piston one. Not the other way around.
@@limamikeaviation6200 if this kit ever does make it to market, it will not cost nearly as much as a cabri or R22. End of discussion. Toss all the words out you want, that will always be a fact.
These things are perfect for pilot training ☺️
Yeah, if the school charges by the quarter hour...
No it’s not good practice… they have simulator cockpits for a reason… a lot of people won’t die this way.
Amazing work guys!!! As an aircraft mechanic I get a little worried about not being able to measure battery temperature , or to control it yet, which would bring some concerns about a safe flight.
How is the weight different with the battery power vs gas vs turbine?
The electric bird is heavier
@@allencox7949 How much heavier? Did the combustion engine version fall within part 104 limits of 254lbs? Does this one?
Yes, EAC, would love to know more about the future APU (gas motor providing power for an electric motor) option works. Especially would love to know the trade-offs on this type of configuration vs just using battery power plant. In general, would love for you to explore why this type of configuration (APU) works for cars, but why it (seems) to not work in electric aircraft. Thanks for your channel.
DEFINTELY want to see more follow up on this episode. Any guesses at public release estimates and pricing estimates would be great. Also, with the added weight of either all the batteries or a hybrid style, additional engine/generator, would this aircraft still qualify as an Ultralight according to FAA regulations? The weight was not addressed in this episode.
I suggest you and the video creator not wasting time on battery-powered heli: it is DOA just from the energy density alone. Don't wanna agree with me? The battery can improve with time? There is a limit from a chemical-thermodynamics alone- pretty much like the second law of thermodynamics ruled out any perpetual motion machine.
@@irvinewayne4086 Not the same thing but i've seen powertool batteries like the m18 Milwaukee go from 2ah 300-400 charge cycles with a 400watt output to 6ah with the same sized and weight and 3000 charge cycles and 1800watt output. There is also improvements to the inverter efficiency and weight too to be had.
I remember going to job sites in the late 90s and it being a spaghetti mess of cords cause the battery powertools just weren't up to the task. Today only the air compressor and shop vac seem to be the only corded tools that are common anymore. That is only cause of increasing battery power/energy density. Idk if it will ever improve enough for a transatlantic flight but there is still much room for improvement
I'd love to see this with the torque reduction and a production ready battery pack.
I`d love to see utilization battery improvement. Almost noone talks about. All these "green electricity" is bullS without battery utilazion.
@@vovanikotin What is utilization? is that cycle life?
@@JD-yx7be yes, end of battery life, not simple dump as garbage, but some kind of refactoring battery chemistry to use in other applications, or full recycle
@@vovanikotin I know the newer LFP batteries can last over 3000 charge cycles over the older 300-500 for NCM batteries but they don't have the energy density and don't work as well in colder temperatures
Would like to stay current of your progress. Very interested and an awesome job.
I built my own batteri\y packs and they worked just fine. I am not an "engineer" but making battery packs and wiring them correctly with the BMS and other requirements is not difficult nor does it require an engineer.
"nor does it require an engineer" but it helps if you know what you are doing.
This is a terrible attitude. Battery powered aircraft are no joke. A fiery death like the Siemens tragedy is the worst way to go. Please don't trivialize the risks.
You can make your own packs, but they won't be any more energy-dense than the properly designed modules that they are using, so there's no point.
Be sure and tell that to John Denver when you see him.
for a full size flying helicopter ? show us a video
Of coarse we want to see a follow up video on the all electric. Bring them on. I want more flight test content. Higher altitude please.
Yea I would like to see the advancements they make on this. That is awesome. Hybrid is the way to go until they come up with a better battery chemistry (or release one anyway). That is so cool! I have been watching the Mosquito helicopters for years on youtube. I don't think I could ever fly one. Ill stick with FAR103 fixed wings. LoL
Love it! I am an aerospace/software engineer/small business owner. I worked for Tesla for 5 years 🤔
8:50 I'm impressed that the cameraman isn't afraid of getting chopped up by those blades considering it's still a prototype, anything can happen
i like how he though it was gonna be a 12 or 24 bolt system haha
LOL, the wires would have to be HUGE...
@@RussellD11 not only that, 12/24 volt has very little torque, and not nearly enough to drive two rotors capable of lifting a load of mass off the ground.
@@missingMBR agree, but I think if you "could" pump enough amps through at 12-24V it would have quite a bit of torque.. But agree 100% its not the safest, or best way.. Way too much resistance as well at lower volts...
@@RussellD11 sorry I got confused there. Voltage is proportional to speed. Current is proportional to torque. So you're absolutely right. You could throw enormous gauge wires at the motor and achieve the same amount of torque. But is it practical, not very, haha.
@@missingMBR they "may" also find going to AC voltage like the bigger EV cars use, may have some weight benefits, and lower temperatures..Will be interesting to see how this pans out and what they end up using.
This electrical Engineer is a smart dude.
Very cool, love the green color. Based on the rotor blade's shape (like an airplane wing) at 10:45, I'm guessing it rotates counter-clockwise?
Great to see an electric helicopter, even that it is a prototype it is a good start. Very quiet and easy to fly as far as I can see. With future improvements on battery density this will be viable. Another idea is to use a Hydrogen fuel cell. That will give a bit longer fly time.
That GREEN though...beautiful.
Very cool.. you could also use regenerative braking to slow the rotor when shutting down.
Sick as hell. 👍
And there is more going on there that we didn't capture during this visit. They are also manufacturing their own rotor blades!
The Wright Bros are alive and well
I love how many people are commenting that it has a short flight time or they have a long way to go. IT"S a prototype folks.
Calm down
Yes, it's just a prototype. Unfortunately, since the fundamental endurance problem is the weight of the battery, there is not much improvement likely any time soon, even with unlimited development of the aircraft.
@@brianb-p6586 🤣🤣🤣 your the exact same person that said airplanes, cars and the internet were fads. Oh you probably thought cell phones weren't going to last either 😂🤣😅
@@antr7493 No, I just acknowledge reality. A battery-electric helicopter will work well, with higher battery energy density. Even this one will work well for very short flights, once they fix the drive ratio; it is just a prototype, so that sort of change should be expected.
By the way, I'm one of the people who gave your post a "thumbs up", but I've taken that away now.
I love the idea of a hybrid. Something like the Chevy Volt where the gas engine provides enough electricity by turning the generator. That's also how a diesel electric train works.
do you know why trains work like that?
Yes, definitely do a follow up on this fascinating project!
This is so great! Glad people are working on electrifying things. They should use battery regeneration as a rotor break.
Great prototype! Are there any provisions for cooling air into the battery enclosures? Would it improve the batteries efficiency at all? Air cooling would be readily available (obviously) from the rotor.
Sort of answered in the video. They're running so low power that active cooling is not needed.
They are doing nothing about cooling the battery modules, but they could mount them to finned aluminum plates and blow air past them, as a crude cooling system. The face of those modules which is designed to be cooled in the one that they have vertical and facing inward in the side packs; it normally sits on a liquid-cooled plate.
Without proper control, they may not want more battery cooling. These cells need to be kept within a temperature range for best performance, and while too hot is a problem, too cold is a problem too.
@@brianb-p6586 Cooling is not needed due to the low power draw from the battery pack.
@@LoanwordEggcorn that's what they say, but a continuous 8 kW per module is well beyond the normal service of these modules. They might still be okay.
@@brianb-p6586 Agree it's higher power per module than the Chevy Bolt donor vehicle, but it's probably still ok. It's a 3C (3 times capacity) discharge rate.
I love it, great video. Keep up the good work, can't wait to fly one. I've been waiting for years !!!
I think if they went with LiPo batteries they could reduce weight...or extend flight time a bit. I think they need more aerodynamic battery boxes as they refine the design; those boxes must create a lot of drag in forward flight, although I'm sure creating lift is eating up more of the battery energy.
They might be able to put the batteries in aerodynamic pods that might have less drag.
That's for sure, this is just the first prototype, a "let's put something together with what we already have and see how if works".
They are using a type of lithium ion battery with one of highest energy density of any battery is just a different anode that is better at stacking the electrons. You might be thinking of old Nickle cadmium batter or NiCH much heavier.
I would not venture into EV aircraft rotary or fixed. The power demand of electric motors is enormous. Study the Laws of the conservation of energy with respect to electricity. So far there is no battery capable of storing enough energy for any practical application. Even EV cars of today have limited range and if the user demands more performance, the batteries will drain quicker.
@throwaway3873 It's a free country, some might say. As of the present, you have the right to make dumb purchases. if you don't already own an EV, go get one. Some people have to learn the hard way.
Tell that to the bumble bee.
Very impressive the amount of sound out of the equation is excellent for stealth work or hunting whit out spooking everything. 👍
In it's cuuent form a bit hard to justify buying this helo - charging for five hours to be on air for mere 25 minutes .
That’s why everyone keeps saying the word “prototype” 🤦♂️ It’s just a proof of concept machine, not a ready for market kit. CFX wants to have their electric helicopter ready so that when that Jesus-battery is finally invented, all they have to do is slap it in the Mosquito, program the controller and start selling them 🤷♂️
You gotta start somewhere!
The main advantage of electric solution is modularity. If a new battery type or energy source appears, you simply change the batteries and that's it. I think it will start to be interesting by 1 hour endurance. At the current state maybe interesting would be changable batteries. And you can operate the heli like the RC heli models. Of course you can not to affors to fly very far away... 🙂

Cool!! There should be a parachute attached for emergency safety as well as solar panels to charge battery while in air.
Idk about the belt system.
is it known to slip if you ram up motor on take off?
Or what if your G force is to high when landing,
causing the belt to slip due to high motor power to slow down the G force for smoother landing?
since it is electric.
does it have a smart system for automatic pilot?
for easy take off and easy landing?
Some drones have that feature.

Go same Shaft/Parallel Circuit.
It is a safer way to charge or produce needed velocity because it is running with the main current power source. For minor or emergency circuit producers, you can thermal or solar charge. But don't forget about the wind turbine charge you are producing with the blades/propellers generating. Small is always better done having nothing. 😊
