Notes for folks who want to go faster: - Make the fuselage skinnier and longer. Fit the batteries closely and eliminate excess volume. - Switch to an H-wing rather than an X, increase the wing span and minimize the distance from the motors to the main wing. This gets most of your wing area available for lift. - Use an actual asymmetrical wing section to reduce parasitic drag from lift. - Mount the wing with some fixed angle of attack to shift lift from the body to the wing. Body lift seems free when you just consider parasitic drag. But consider induced drag and suddenly it's not so awesome. You want the wing making lots of lift in cruise and the body closer to neutral. Given how big your fuselage is compared to your wing, you'll always get a lot of fuselage lift. - Polish that surface! At that scale, you want surface deviations that are *tiny*, like under a thousandth of an inch.
At these speeds you get all the body lift you need from 1 degree angle which means there is almost zero induced drag. No need for wings because the body is pretty big dictated by the battery size.
@@Mike-Bell How much does it weigh, about 3 kg? Body is about 15 cm diameter? Hmm. You're right. At 450 km/hr, sea level air density, dynamic pressure is 9600 Pa. Induced drag from 30 N of lift is maybe 1.7 N, which is 210 watts of drag. If you figure your ESC, motors, and props have a combined efficiency of 50%, that's 420 watts from the battery, or 2.5% of your battery power. I still wonder if there's a way to make it skinnier. What batteries do you use?
Well done Luke and poppa! I love the family bonding and time spent together on this and other projects from you guys. Cherish these moments together, and cheers from one father to another!
Congrats on the new record. You are helping to push the boundaries of FPV racing drone technology!! For a while, most quadcopter companies were so focused on 3 inch, small, light weight drones. Now there is a swing back towards 5-10 quadcopters with S8 batteries and monster ESC's. Soon we will push into S10-S12 monsters and quadcopters that can maintain flight well over 1-3 hours! It seems like every month some inventor in their lab also comes up with another use case for quadcopters. Whether it be chasing F1 cars, flying in the air and water, product delivery and a host of defensive/offensive war tech.

I’m curious why you’re using such a conventional design for your props. There are more efficient, powerful designs that are used in real aircraft that could be scaled down that could offer all sorts of advantages.
Availability. Printed props wont last a second in that application. Similar when there’s hype about toroidal props. And Injected molding is super expensive to setup
@@LukeMaximoBell1 What about sintered metal. Again, I’m no expert, I’m just asking. I am fascinated by this stuff. I fly professionally and over the past 15 years or so there have been some really neat advancements in prop tech for actual aircraft. I’m not sure what kind of RPMs your props are seeing but I imagine it is on par with something like a modern turbo prop. In that area more and more older aircraft are seeing their three and four bladed props replaced by 5, 6, and 8 bladed props with modified shapes like paddle board and modified tips. There are a few companies playing around with contra rotating designs that are interesting, making kind of an external jet prop. These mods greatly improve performance in thrust, airspeed, noise, and fuel efficacy which that last part may or may not relate to improve battery life. One of my hobby’s is shooting and there have been some really impressive strides made in metal 3D printing. There are a few suppressors on the market now that simply couldn’t be made without a 3D printer. The pressures involved in containing hot gasses from a muzzle blast are exceptionally high. I can’t imagine that something like that would fail in your application. Composites and hybrid composites likewise have proven to be very durable. It would be interesting to see these strides getting scaled down to use in UAV/drone tech. Good video on the subject ua-cam.com/video/ojVNOj-q3SQ/v-deo.htmlsi=L-SVxDF0cBbn48dT
@@SuperTrb0 and to add, the bigger prop size is the more efficient it is. So just by scaling down props in jets or boats doesn’t guarantee itll be efficient and economical.
Congratulations! Question: I think the motor is not a V3115, according to the specification it cannot give more than 7928 W instead of 8.8 kW, also the reference on the video was blacked out. Conclusion: I think the real reference motors gave about 70% of their power, so maybe there is some possible improvement to go faster (stability seems to be the key, right?)
Motor ratings mean absolutely nothing. They will pull however much current you give them until they smoke. And such builds already operate components beyond their specification ratings. "Power" isn't everything. Prop tip speeds were already going transonic. It's very easy to make rpm but pure power is not the limiting factor.
I don't think they were using "Nirmal operating conditions" in this video. Batteries have a C rating, which indicates how much output they can deliver. This clearly exceeded that rating, as the batteries caught fire.
Wow, that opening in the front was perfect and if it's opened in the back for the Air to pass through unimpeded I can imagine it must run cool even at full throttle, just like a PC pull air in and expel air out for cooler components, probably would go faster as well, just have to create a barrier inside to keep condensation to a minimum on the components especially on cooler days
This was so inspiring! I need to experience this kind of speed! Are there any plans to making the parts and tune available so we can build our own speed demons?
@@zachmoyer1849 Thats the Dutch Drone Gods (DDG) yes. I wouldn't call it a redbull drone just because they did some canopy optimization and put their logo on it. Anyway, they said its the fastest camera drone that can last a whole track and it probably still is.
Apples and oranges. Not dogging on this channel or anything but DDG has way more resources at their disposal. If they wanted to make a drone for this purpose, I think they'd give this drone a good run for it's money.
Are the T-motor Velox 3115 custom or is it a typo with the kv of 1500? They sell a 1050kv which would make more sense. On top of that, a 1500kv motor on 8s and 7" props would break the sound barrier at the tips which would start to throw things out of wack.
It’s not a typo but we settled on the 900kv 3115 with 12S and 7x11 APC prop. It won’t break the sound barrier because the load won’t allow the props to get up to high enough RPM. With a load motors will never reach their voltage x kv = rpm theoretical calculation.
Out of curiosity, any particular reason to use FDM over SLA/some other method? Theoretically the aerodynamics should be significantly worsened by the layer lines-- and FDM parts are definitely heavier than a lot of other materials (maybe LW-PLA could improve things slightly with FDM?)
So what is the motor u used in the end ?? I mean u said u would replace the 4 T-motors with another ones of slightly different kvs but u didnt get in details

Did you guys do the ole measure diagonally for the motor mount holes and then find out it was side to side?? I’ve done that a few times. Also I might have to try my hand at the record now! Looks awesome!!
No we didn’t in the end. We used the APD 120A ESCs. But a bunch of those failed. Honestly, I don’t have a good option for ESCs at this point. Going to try Flycolor next.
@@LukeMaximoBell1 Thanks so much for sharing this valuable info - I just watched your dad's video, too - awesome! I'm planning a 12S 11" build that I calculate will draw at least 8kW.. I'm interested as to why some of the ESCs went up in flame - the amp draw was well within spec.. perhaps the eRPM? Or maybe when you slowed down the cooling airflow stopped and the heat in the fets built up? This would indicate that escs need active cooling for some time after they're throttled down. I've been thinking about the flycolors, too, but they scare me a bit - not sure of their quality and the 120 and 160s are very heavy...
New watcher and I just wanted to say amazing video/project. I think its so cool to see what the kid from The Sandlot (movie) is up to all these years later. Fun fact: I never knew he had an accent before this video. Joking aside very very impressive, much respect bro! See ya on the next one, new new fastest drone.
what would happen if the props where fully housed on the rear with the overal rear opening being reduced a bit like a funnell? normall with a large volume of air being forced into more narrow corridors of streams it vastly increases the speed of the outgoing air so not only would you have the pull effect from the props but also increased speed of the wind speed from the jets. also if the jets flowed along and down the body so far that would also increase the air stream effect of on the body giving more speed. or i could be wrong. if i'm right you could gain a extra 20 - 30% speed increase
Random question: Can the wings provide and lift? Is it ‘flying’? Like a plane or does it always remain a quad? Would it be more efficient to have a certain way up that provided lift through the wing or is it not worth it?
Fabulous really well done. Your determination to complete such a project celebrates what a father and son can achieve when united by a common goal. congratulations to you both
Incredible work! Curious about the trade-offs you made compared to Red Bull’s drone, which needs to excel in cornering and filming. How did you manage thermal issues with batteries and ESCs at such high speeds? Did you use advanced CFD simulations for aerodynamic optimization? Balancing lightweight construction with the necessary strength must have been tough. Interested in your material choices and the control algorithms you used. Beating Red Bull, known for their speed and video quality, is truly impressive. Well done!
Congratulations! This is the first time seeing your video. I like that you showed all that is involved in making a successfully flying drone. I think your expertise would be useful in the drone racing circuits. It is there that the problems of having flying cars can be worked out. Who knows What comes after? Good luck.

This was so inspiring! I need to experience this kind of speed! Are there any plans to making the parts and tune available so we can build our own speed demons?
Thanks so much! 🙌🏼 there are plans in the works to make a commercially available drone.
Now Redbull can’t call their drone the fastest drone in the world!
wimps
DDG never did and I don't think Redbull has a drone?
@@Kai-P they basically sponsored a guy that built one and helped him make it out of carbon fiber there is a video on youtube about it.
@@zachmoyer1849 Thats the Dutch Drone Gods (DDG) yes. I wouldn't call it a redbull drone just because they did some canopy optimization and put their logo on it.
Anyway, they said its the fastest camera drone that can last a whole track and it probably still is.
Apples and oranges. Not dogging on this channel or anything but DDG has way more resources at their disposal. If they wanted to make a drone for this purpose, I think they'd give this drone a good run for it's money.
AWESOME! Putin wil give you a call to make an order!
crush the competition @0:15 = 👌
First comment about this 😂 glad you noticed!
Second time watching this video, I loved everything about it🔥💯🔥💯
Are the T-motor Velox 3115 custom or is it a typo with the kv of 1500? They sell a 1050kv which would make more sense. On top of that, a 1500kv motor on 8s and 7" props would break the sound barrier at the tips which would start to throw things out of wack.
It’s not a typo but we settled on the 900kv 3115 with 12S and 7x11 APC prop. It won’t break the sound barrier because the load won’t allow the props to get up to high enough RPM. With a load motors will never reach their voltage x kv = rpm theoretical calculation.
Can I borrow it....plzzzzzzz?
Only rich people can afford to make mistakes.
Get that to Ukraine.
That's incredible work guys !! Shockingly quick and stable, I know it took a lotta work to get there, but jeez you got a beast now !!
Thanks so much 🤩 so glad we got there in the end. There were many times we’re giving up seemed like the easy way out
Would the use of torodial propellers increase the speed?
Out of curiosity, any particular reason to use FDM over SLA/some other method? Theoretically the aerodynamics should be significantly worsened by the layer lines-- and FDM parts are definitely heavier than a lot of other materials (maybe LW-PLA could improve things slightly with FDM?)
FDM is the only one big enough that would work I think.
So what is the motor u used in the end ?? I mean u said u would replace the 4 T-motors with another ones of slightly different kvs but u didnt get in details
I never thought a quad-drone could fly this fast! Absolutely respect what you've achieved with your passion, knowledge, and persistence.
Thanks so much! 🙌🏼
I am so happy for you blokes in South Africa flying a home-made drone to 300mph is truly a feat in itself.✌️🇺🇲🇧🇷
Would it be possible to use honeycomb design for the frame and most of the shell to reduce weight but at the same time providing rigid structure?
Which CAD system do you use for drone 3D modeling? Thanks in advance
It was designed in Blender ua-cam.com/video/RoSSaSkOTTc/v-deo.html
09:01 please tell me what camera you use ? for that filming plz !
Sony A7siii 14mm GM Len’s
That was so fun to watch.
Almost 300 mph is insanely fast for ANYTHING let alone a drone.
Have you considered using 3, 4, 5, 6, 7, or 8 bladed props? Maybe with slightly biggger/more powerful motors if neccesary?
Well Done Great Work...Keep on Pushing on , We Limitless....Legendry Work
Wow!!! Awesome that you and your dad accomplished this. Hope you will market this for sale in the USA!
Maybe in the future!
Good idea. Here is my design video Designing the worlds fastest Drone | Guinness Record Holder

Being a foster child having a pa as A1 golden as yours is only for me to be imagined as the love for you is a reality thank you for sharing love always peace to you
Thanks so much!
What flight controller/transmission systems did you use?
Did you guys do the ole measure diagonally for the motor mount holes and then find out it was side to side?? I’ve done that a few times. Also I might have to try my hand at the record now! Looks awesome!!
Thats exactly how I screwed up the motor hole dimensions 😂
We welcome competition
Yup 😂 but at least the term wheelbase is now very clearly understood! Haha
@@Mike-Bell 30.5x30.5 FC and ESC boards are side to side, 19mm motors mounts are diagonal. Gets me every single time even when I’m aware of it 🤣
Just checking. Are you sure the V3115 T-Motor you are specing is 1500kv? I only see up to 1050kv on their website.
Those ones were custom made. However the final spec motors we used are the 3115 900kv
...did you settle on those t-motor cine 12s 80A ESCs??
No we didn’t in the end. We used the APD 120A ESCs. But a bunch of those failed. Honestly, I don’t have a good option for ESCs at this point. Going to try Flycolor next.
For batteries go for the Bonka 200C. Dogcom has poor quality control and questionable ratings.
@@LukeMaximoBell1 Thanks so much for sharing this valuable info - I just watched your dad's video, too - awesome!
I'm planning a 12S 11" build that I calculate will draw at least 8kW.. I'm interested as to why some of the ESCs went up in flame - the amp draw was well within spec.. perhaps the eRPM? Or maybe when you slowed down the cooling airflow stopped and the heat in the fets built up? This would indicate that escs need active cooling for some time after they're throttled down.
I've been thinking about the flycolors, too, but they scare me a bit - not sure of their quality and the 120 and 160s are very heavy...
@@mlentsch The ESCS that went up in flames were faulty. I'm trying Flycolor for my next build so I'll see if they are good or not.
Great Work!! Question: what is the brand and model of your thermal imaging camera?
Flir
New watcher and I just wanted to say amazing video/project. I think its so cool to see what the kid from The Sandlot (movie) is up to all these years later. Fun fact: I never knew he had an accent before this video. Joking aside very very impressive, much respect bro! See ya on the next one, new new fastest drone.
Haha thanks so much! You aren’t the first person to make that connection 😂
Congrats Luke. Shows what we can achieve in South Africa.
Congratulations man the hardwork always paysoff
what would happen if the props where fully housed on the rear with the overal rear opening being reduced a bit like a funnell? normall with a large volume of air being forced into more narrow corridors of streams it vastly increases the speed of the outgoing air so not only would you have the pull effect from the props but also increased speed of the wind speed from the jets. also if the jets flowed along and down the body so far that would also increase the air stream effect of on the body giving more speed. or i could be wrong. if i'm right you could gain a extra 20 - 30% speed increase
Random question: Can the wings provide and lift? Is it ‘flying’? Like a plane or does it always remain a quad? Would it be more efficient to have a certain way up that provided lift through the wing or is it not worth it?
What camera did you use for the thermal footage?
your relationship with your dad is as awesome as the world record
Thanks ☺️ here is the design video Designing the worlds fastest Drone | Guinness Record Holder

Fabulous really well done. Your determination to complete such a project celebrates what a father and son can achieve when united by a common goal. congratulations to you both
Incredible work! Curious about the trade-offs you made compared to Red Bull’s drone, which needs to excel in cornering and filming. How did you manage thermal issues with batteries and ESCs at such high speeds? Did you use advanced CFD simulations for aerodynamic optimization?
Balancing lightweight construction with the necessary strength must have been tough. Interested in your material choices and the control algorithms you used. Beating Red Bull, known for their speed and video quality, is truly impressive. Well done!
Congratulations!
This is the first time seeing your video. I like that you showed all that is involved in making a successfully flying drone.
I think your expertise would be useful in the drone racing circuits.
It is there that the problems of having flying cars can be worked out. Who knows
What comes after? Good luck.
Thanks so much!!
Awesome record congrats! What airfield was the attempt filmed at?
more than 2000w pr motor is an achievement on it's own. Congrats Luke and Mike
great job, you have shown how proper flight dev needs a lot of trial and errors, and iterations, how resilient and patient the operators have to be !
Absolutely Phenomenal!! Congratulations!!! 🚀
Could you please share a link to the design-video mentioned in this video?

Luke, I think you should curve the 4 arms of the drone for better aero, the 90 degree angle currently hold a lot more air
Brother!! That is absolutely insane!! I’d bet if you put a lacquer clear coat and polished it you’d steal more yet…smooth is fast and you want it mirror polished
Yeh that would be epic! Mayve we will try next time.
I'm 65 and that's is the wildest this I've seen in my life.
I've been in the jump seat of a P-51 going nearly 400 mph, but this would keep up. Wow.
Congrats to you and your dad. This is absolutely phenomenal!!!
Luke and your dad, , A Very Big Congratulations !!!
Thanks so much! 🙌🏼
The terapy part is sooo funny!
Amazing project and drive to keep on pushing. Congrats
Glad you enjoyed it 😂
fantastic job. Do you also have a link to the Blender file? Keep rocking, cheers!
Hearing “just 400km/h was insane to me. Well done on your work brother
You’re smart enough to have me send you the parts for a water jet cnc system. It’s much more satisfying to do it as much as you can yourself.
