Thanks for posting your video! Really enjoyed it. I'm finishing up my batch 3 build this week. Really a nice kit. I look forward to many "electric chair" flights! Paul and Zach are the best!
www.pocket-lint.com/gadgets/news/130380-future-batteries-coming-soon-charge-in-seconds-last-months-and-power-over-the-air You can expect batteries to be 2-3 times more energy dense in the near future.
folds up enough to fit in a small hatchback like mine. I'm in the waiting list for the next batch, hopefully they start another production run before the summer season is over!
Overall, I am not a fan of the four prop design (poor efficiency), but your build is fantastic, and I love the way it folds down. Lovely flight video, thanks for sharing.
Speed: same as any paramotor - depends on wing and auw. Thrust is ... enough! :) Range: same as any flying machine - depends on winds and other conditions. Not much. At full power your battery will be done in 8 minutes. Push it longer and you'll be replacing them soon. Charge time: same as any battery - depends on how many cycles you'd like and how much you spend on your chargers. Mine takes 4-5 hours. Swapping out set of batteries would take less than 5 mins.
What was your charge percentage remaining after the 10-minute hoppity-hop? Most charging systems which would manage such stacks of awesomeness will tell ya.
Subbed! - So....Congrats, that was a great video. It's good to see it all from your POV. I will get one of these beauties one day. Please make more vids, cheers!
Gee that all looks familiar :D except the landscape of course. All my flights are around 10 minutes so far. Gotta save some for a go around. I've taken to switching on after strapping it on and giving a loud "Clear Prop". It's safer and it's practice reaching the switches.
That's awesome! With 4 smaller props (in addition to configuring them to cancel the torque effect which is very cool) does a prop strike deliver just 1/4 the energy of a standard prop - making it safer in that regard? Or are there other off-setting variables like a smaller blade being able to travel through tissue more easily, etc. etc. Just wondering if the 4 blade design provides added safety as well. Great stuff!!
Looks so good.......if you had full power for 10 mins and went up to say 2000ft then that might result in a very nice 30 min flight which to me sonds very good............................
My favorite part was pulling it out of the back seat! Could you smell the fumes from the batteries like you would gas :>) Great vid and flight - how was your throttle control ? Good thrust at take off(very smooth by the way) -- damn it man, give us some details :>) Working on my batch 3 now. Cheers
Throttle is... interesting. I don't like the thumb control... you can't guide your A's up and use the throttle at the same time... which means you have to muscle the wing up yourself... come off the As and then find that throttle. I would hate that if I was launching in snow or some slippery condition. Response is instant of course... and I found it comfy to use generally... but give me a short bottom lever any day. The throttle cable is very thin, and I ended up pinching it in the arm... so I had to cut it open and inspect... it was fine (it's a 4-conductor... very small wires, wrapped in fine steel braid) I got hold of some 1/4 black vacuum line which had an ID JUST big enough to receive the cable... so now it's well protected. It's also zip tied to the shoulder of the arm so that it won't be pinched again. Check the video at 24 seconds to see what I'm talking about. You can see where the covered cable starts... and the original, unprotected cable runs off to the right and into the guts of the machine.
It's reasonably strong... but nothing like a mechanical cable you would find on a gas machine. I would say that my little bird is fairly fragile overall (a problem with all carbon fiber machines). But if I stay on my feet, shouldn't ever be a problem.
@@kornerederparamotor Not talking about looks... It's that CF shatters... while metal bends. You can straighten out metal... but you can't straighten out CF. Once you smack it hard... that's that. You can bend and straighten titanium repeatedly... it's amazing. I watched a guy slip during launch... and every CF part on his Scout was damaged... prop, ring, supports. A very sad affair. BUT, strength to weight... CF is hard to beat.
Yes you are right. But there are constructive solutions to eliminate all problems. as an example: at my cage rings, the cores are a layer glueing of esche funier with cfk and gfk layers. that's as stable and elastic as a sports bow. or similar to the construction at ski. I use a lot of unidirectional cfk fibers in parts that are extremely under stress. if it is not allowed to sputter, a hybrid cfk - afk fabric is laminated under the last layer cfk, just like military helmets. with extremely lightweight cages, an extremely thin aluminum profile in drop form is used as a base and coated in a special winding technique with cfk fibers. These components are elastic and almost indestructible. you can control that exactly. I do it all just as a hobby. Of course I also use Titan sometimes. but cfk is much easier to work with because you can glue it. For propellers I use prepreg as in real aircraft construction. an example is the pluma paramotor. this one has the same material and is extremely stable. Best regards
Nice indeed but very inefficient :( You could greatly improve overall efficiency by doing away with the cage and mounting the engines in paires, 2 on each side and about 20cm below shoulder hight. The props work in a Push-Pull configuratuon. Further, build a carbon-fibre shroud around the props. The shroud must be almost touching the props. My props will be 500mm diameter and the shroud will also be 500mm. Initially the props will touch the inside of the shroud but will quickly "sit" themselves in, with almost no space between them and the shroud. The props will be contra-rotating within the shroud. I have worked out most things and will build my own setup in 1 year or so. Furthermore, the shroud has a one inch lip at the front, to further increase efficiency.
Ducted fan design... i was thinking about the same concept. Counter rotating props are also more efficient and unit will be more compact. I hope you will upload video once you finnish your project
I'm not quite ready to fly her until the battery is gone, but I did a 13 minute flight the following day. I'm going to guess around 15 minutes, based on my recharge (she took about 80-85% charge after the 10 minute hop).
great, thanks for the nice vid. The lipo's on my back would deter me from flying this a bit however... have you ever seen one go ballistic? Its not nice. even from a few meters away. Being only a feet away when one blows and is stuck to your back... pfew...i guess a guy with hair on his back wouldnt need a wax anymore. ever.
One of the few reasons for my hesitation ... I've accidentally blown up a 2000mah lipo on my leg, comparable to gasoline burn. Thise bonkas are huge.... I can imagine the heat would do damage outward of several foot radius
Mine has a battery release. Been flying mine for a year and a half. If you take care of the batteries (proper charging procedure) it should not be an issue. Have a great day. system ua-cam.com/video/Be3dKjtMtdU/v-deo.html
I always see it as sooo wasteful to replace one large prop with multiple small ones. I have never done the calculation but pretty sure the efficiency loss would not be insignificant... not trivial with battery power density being so poor.
was looking at their specs for motors... 50cc electric spinning 22x10 props... as someone flying RC planes with that size motors, they selected the wrong spec motor. they should lower the Kv and up the diameter of the prop, improving efficiency, thrust and flight times. punch that puppy up to 24" props with same pitch with lower Kv motors... or, pull the voltage down with more cells in parallel than serial, and up the prop diameter, you'll thank me later :)
Too much of a chew putting all that together by the time id f about assembling it id of gotten bored of flying or tge wind would have picked up but a great video anyway
Way too loud. Very short flight times I'm sure. Can't drag those lipos down below 50 % or so. This seems to be impractical . Can't travel any serious distance or time. Can't carry extra batteries because of weight. Those batteries probably cost a few hundred dollars. Couple of gallons of gas costs maybe 7 bucks and goes for a couple of hours. PLEASE answer flight time and battery cost questions. This is just a cute experiment, not a real alternative to gas powered craft.
Thanks for posting about the OpenPPG! Please keep the videos coming. More thoughts and impressions would be fantastic.
Love the name sends a cold chill down my spine !
Super interested in the future of electric paramotors. Hope to see more videos! :)
ua-cam.com/video/Be3dKjtMtdU/v-deo.html
Superb ! Great flying ! The first time I saw one with two props.
Has 4 props
Love the simplicity... Looking forward to next batch.
I enjoyed seeing the detail of the assembly. Nicely covered and very enjoyable video.

Greating flying.
Looks awesome, please keep us updated to your progress. Really interested in the length of flight you can get...
This is the video I have been waiting for !! Brilliant!!! I can’t wait
Great video.thanks.
Cool project! 4:37 What kind of (wired) controller are you using? And what other types have you seen?
Awesome. Interested in knowing speed, range, charge time and or battery replacement.

Man we need to see this attached to a wheelchair. Looks like it would fit pretty easily on one
Plenty of power!
Great video, whats the spec on motors esc etc please. thanks
What was your charge percentage remaining after the 10-minute hoppity-hop? Most charging systems which would manage such stacks of awesomeness will tell ya.
Fantastic concept. But in terms of travelling, I am not sure airlines allow you to check-in that many huge batteries.
Subbed! - So....Congrats, that was a great video. It's good to see it all from your POV. I will get one of these beauties one day.
Please make more vids, cheers!
Are there any monitors showing the power left over.
Gee that all looks familiar :D except the landscape of course. All my flights are around 10 minutes so far. Gotta save some for a go around. I've taken to switching on after strapping it on and giving a loud "Clear Prop". It's safer and it's practice reaching the switches.

Hello,
Can you please tell me the motor and prop specs?
Please
Nothing to hold that outside frame together besides friction? Lots of vibration going on there...
awesome stuff!

@@paradad9609 I just use my index fingers to hold the As on takeoff instead of my thumbs. I actually feel like I have more control that way
Would a Bluetooth throttle control not work? No cable to hit the prop etc
What flying time do you get out of a full battery charge
Sweet!
Ok...15 minutes I read....and the engine size 2-3 KW each ?
Seems like theres not very much power. Would you compare it to like a top 80?
Its comped to a moster 185... openppg.com/
...great basic idea BUT way to LOUD for us here. !!!!! Question... what handle is that U use? Thank you.
Is there a throttle lock/cruise control? Program the steering and you're set.
what is the approximate time from opening up until unit is ready for flight?
Какой вес установки?
Can I know the equipment specifications ?
openppg.com/
Nice Video... I noticed you have wooden props. would a carbon prop affect the how loud the sound is (noisier or quieter)?
Nice
What is the total weight of the unit with batteries? Thanks
48 lbs. (minus glider)
Love it. How strong is the throttle button? Looks like it could snap if you grab it wrong.
It's reasonably strong... but nothing like a mechanical cable you would find on a gas machine. I would say that my little bird is fairly fragile overall (a problem with all carbon fiber machines). But if I stay on my feet, shouldn't ever be a problem.
hi, it's not the carbon if something looks fragile. It is the construction and the experience of the designer.

Also this system could be paired with freeflight harness
You two should go on the electric ppg open source forum and execute your ideas there. Its a community project that he is flying. openppg.com/
Hy..man..!¡.😊..how much is the weight of the motor...and how many minits it can by flight...???
Thankyou
Great addition to the sport! Do you know the time in flight yet?
I'm not quite ready to fly her until the battery is gone, but I did a 13 minute flight the following day. I'm going to guess around 15 minutes, based on my recharge (she took about 80-85% charge after the 10 minute hop).
Paradad Love this, did you build or was the manufactured by Open PPG?
@@DaxDunn-MotherNatureCures Open PPG built her
OF COURSE HE DOES. HE JUST DOESN'T WANT YOU TO KNOW HOW IMPRACTICAL THIS IS.
Flight time?
So how much will this unit set us back
3100 on their site
look good but only half hour that no good small generator to charge them in flight
this is awesome! are you in NorCal? I'd love to see one of these things up close before I build one myself.
Hello Man, it good this!
10 minutes...could it do 20 minutes ?
