I’m interviewing the holders of the world drone speed record. His drone went 200 mph!!!!! How do you make a drone go 200 mph and break a world record? You might be surprised to find out it’s not 10S power! It’s actually more about aerodynamics.

){kind=link}
quick q – with this setup why not move the batteries out under the individual motors and shrink the electronics too? You could basically shrink the center to 3.5 x 3.5 cm and have “an arrow” to ride. The center could be removed completely if you for instance ran a 3 gyro setup (F7 is fast enough) on the rim? Probably for good reasons – I’m curious. If you don’t have the time to comment – nice f.work guys 🙂
100k special? ???
I will put a traffic cone on a my chameleon 😀 200mph here we come!
new transformation is made. fvp drone racing vs fpv drone drag race, aka rc rocket!!!
Very interesting. A small correction – the power to overcome drag goes up with the cube of the speed.
This is awesome, to solve aerodynamic stability why not get a gyro from like a rc motorcycle to buffer out the counter actions the motors are making so that the engines can focus on the speed plus streamline the fuselage, like a blood vain on a buck knife. Allowing the wind to be trapped in a vortex channel to allow less disturbance buy the blades. And also use a 360° FPV cam to watch on all sides the disturbances!
Might check out the ballistics data on certain shapes just a suggestion,
Have you tried a chine shape?
Love the video bro OCD-FPV in the house ???
At 90 degree camera tilt Yaw becomes inverted roll and roll becomes yaw. Any compensation done on the sticks/controller for flying it or just the hell with it and fly the damn thing?
Also, with dual cam integrated flight controllers now out you could toss a micro camera at the base that is basically zero uptilt for landing while the other camera is at the nose and pointed where it needs to be for speed runs.
Thanks! “why not move the batteries out under the individual motors” I had thought of this concept, but I think it came down to a moment of inertia issue. The motors will have a harder time keeping the quad stable, therefore speed would suffer. I agree that the batteries are a problem. Too bad we can’t order them in whatever shape we want 🙂
No compensation on the sticks and the camera angle is actually kinda low at 45-55°. Landing isn’t as hard as it seems: I put it into angle mode, remove my goggles and gently land it LOS. I’d like to put a metal spike in the tail so I can hover about 10 feet off the ground, disarm, and lawn dart the landing.
Ryan sold me one of his frames and it’s very fast
Rossa speed challenge required me to have two runs , rc cars though…I had issues passing 170mph on 8s with rc car
@Ryan L It would definitely fly like a pig. Is using “engine throttle up/down” to do the steering optimal when trying to achieve a max speed – wouldn’t control surfaces offer a better solution or is the computing power not there yet? Some materials stretch/tighten with electrical currents – for simplicity imagine the skimpiest squirrel suit f.x. “armpit” fabric electrified (no servo lags).
Another wacky thought when stability is the main problem – why run the main weight in a fixed setup. Imagine a kite-surfer equipped with a fixed pole instead of a line, trying to control the kite that propels him – impossible at high speed. The wind-surfer on the other hand solves the problem by reducing the “engine size/sail) and brings it in close in a fixed frame. It then becomes manageable but the kite-surfer will laugh his ass off when it comes to raw speed. Have you gone down this road?

Had to pop this one in as well: why do you want electricity to be the carrier if it requires the engines to be positioned at the corners. Why not use a central engine – with air carrying the power out to the props (if propshafts are ruled out)? Does the compresionability of air make it too slow for direction control? (pardon the crp spellings)
Loved the interview! I have a question though! Wouldn’t angle mode set at 90 degrees ensure that you’re always horizontal at full nose down?
Why do both designs have the props in turbulent air? Don’t try to strap four props to a tapered bullet and expect it to fly like a tapered bullet. Make the shape of the nose like a Phillips tip screwdriver smoothed and pulled out on each edge to feed clean uninterrupted airflow greased lighting slick into the props. Both designs are simply not the most efficient. If you drag each model through water you would get cavitation (bubbles) or drag at a low speed. Fluid dynamics for anything that flies is best tested in water. Good Luck guys
Airships! Check out Aerodynamik of Airships. There are methods to predict lift and drag of
rotationally symmetrical Bodys. Problem will be the interaction between body and the relative huge Propellers.
My suggestion would be to steer the 4 fins with ruders. The faster the vehicle becomes the more efficient are ruders…
Ask here for questions regarding Airships:
Oh man it’s coming. The future of speed flying is finally here lol
If in plus config the bottom motor is 100 and the other 3 at 80, why not go 1mm up on the stator on just the bottom motor and half an inch up on its prop? Then at the exact right combo all 4 can be 100%
Great video! The other 2 videos say private though, so I can’t watch them.
top speed cars dont do the salt flats in both directions…
I just said the heck with it and fly the thing without over thinking it. But I take off and land LOS. There is of course a learning curve.
I should have said drag force, not power. Drag is 1/2 p*v^2*Cd*A. The theory gets you in the ball park, but this stuff is tricky to predict, especially if you can get laminar air flow over a good section of the ship. I never expected to be able to go +150MPH on just 1kW of power. My motors were at 80% of their unloaded KV which was very surprising, right in the peak efficiency sweet spot.
Looks like a rocket ship! I can’t imagine flying that.
Someone need to throw a 360 camera on the end of that dildo.
sorry guys.. this is a drone also.. just not a multirotor…
Fixed wing drones can be faster. Is this just for multirotor drones?
happy new year mate….:) its a “idea” and i really i hope you dont mind i ll post it here (you can delete it of course) …trying to help anyone who needs or want real money in a simple way …. “From this very moment you are reading this .Like ANYTHING in your life…this tiny message can be nothing or EVERYTHING to you..Try limit your thoughts for this instant moment you keep reading this.That this is ONLY about yourself start making more MONEY and try to play the “game” with the maximum less effort smart – dont think negative dont think anything else for now-Game is an examble …think of it as an interactive role playing game like any other….just now click-SUBSCRIBE(starting this game) click”like”…and leave any comment to this link(so you can be found easy by other players) .. leave the rest to others and try FOLLOW these tiny rules- be CONSISTANT- try to do the same to every single (player)on any moment you find… even 1 second- there is no why …..EVERYTHING its up to you now….share this message to anyone if you believe there is a 50-50 chance it will work and before you know it you will recieve the first check…..NEVER FORGET ITS ONLY FOR YOU ….leave the rest to the “Game”… just “play” now…!!!there is nothing to lose only this 0.001s you need act for YOU!!!the more you share it the bigger the chances …. ❤” …and yea most of people wont understand this or how easy can be or how hard…i was thinking to make a video to explain more …..but…there is a lot of buts here like for everything …..i dont really know if you or anyone can “Follow/understand” this…sorry in case you think of it like a spam or something like that…
Send an LOS frame to Quadmovr… he’s just one of “those guys”, who will bring out this frame’s true potential 🙂
I have so much fun flying LOS that I have a bunch of FPV paraphernalia but have only flown FPV few times. I would love to have a race quad to fly LOS.
Do you use ducted propellors? Would this give an increased efficiency or would the extra weight and drag prove to be a problem?
The Red Rocket Happy Puppy Drone Shatters the Laws of Physics like Darrel Dawkins on a NBA backboard. The Wright boys, Lindy, Milly E, Chuck, Howie, Niel and “Chappy” from Iron Eagle and its real bad sequels will Forever be Shadowed by those two dudes who made a 200 mph Butt Plug and Dogs Dork.
If you are looking for this in the Official GBOWR it’s on the last page under “W” as in “Who Gives a Shit”
I like green props. (Perfect comment amidst the physics equations. LOL)
I thought 200+mph was pretty common among rc drones, especially the pulse-jet guys. Did no one think to look on YT first? There are literally metric tons of videos of fast flying. *World record????*
Hej Joshua Bardwell, is the Bardwell F4 FC a product of yours? Or is it pure coincidence.
It’s mine of course!
Maybe I should have said quadcopter in the title instead of Drone. There are separate records for multirotors vs. fixed-wing.
@Joshua Bardwell Ah nice! Hej what Frsky receiver would work best on one of those?
And quick non related question, do all Frsky receiver include the 3pin connector because the description only says bind-plug.
Not all FrSky receivers have a 3-pin connector. Many have a different connector or solder pads only.
I recommend the RXSR receiver or the XM+ if you don’t need telemetry.
@Joshua Bardwell Ah those RXSR have a link in the description for the 5-pin cable, sweet thats what i was looking for.
Seems like none of the receivers come with the cables and i couldnt find them so that is solved now 🙂
Thanks man this makes things alot clearer for me.
@Joshua Bardwell Sorry, yeah — that became clearer partway through the video. Still a big accomplishment!
What’s a “drone”. Fixed wing goes much faster.
“Your going to learn something today” – Like that is something strange. Don’t people learn something everyday? How is this special? I find it a bit pretentious a statement to start every video with. Just my two cents. In general the video content is great. I just find the opening repeatedly irritating.

Welcome to the channel, glad to have you.
In regard to turbulence, wouldn’t adding vortex generators work? They are commonly used on aircraft. The vortex generators could also be adjusted and/or retracted based on speed.
Hey, it might have been said, but what direction do their props spin?
The fastest flying Dildo 😀 hhahah
The fastest flying Dildo 😀 hhahah
So he mentioned that there are airfoils on the arms. At what point is this considered a 4 prop “plane” rather than a quad-copter? Is it purely the fact that quads use varying thrust to change direction? Personally I would have said when your design is intended to give lift.
Any criteria that depends on intent is ripe for abuse. It just leads to competitors sneaking lift in without “intending it”. As for the definition of a quadcopter…. ask Guinness.
Would it disqualify it from the record to add wings?
If you like RPM, check out my 2,088,600 RPM, 34,810 rev’s per second, 733mph, and 7.3 million G’s project
Don`t diss LOS flyers, it all started with us 😉
By that I mean the entire RC hobby..
Don`t worry though, I`m becoming one of you very soon, lol.
@J Huff well said.
ring turbulater
ZZZOOOOOOOOOOMMMMMMMMMM
Unfortunately when you have wings and lift its a PLANE! When you want call it a drone or quad there have to be NO wings…. That explanes why are you able to use 100% power for thrust and 0 for stability which is made by wings… so again PLANE!
Evolve. Where’s the next propulsion system? Obv maxing our simple props. Key question, what’s next?
