Thank you guys for all of your support! I hope you enjoy the 100% FREE set of instructions I put together to build your own: hackaday.io/project/191240-flying-rc-drift-car
Tremendous amount of respect for releasing everything open source. For all the time and effort, blood, sweat, and tears( literally) you put into this and not trying to directly capitalize financially on this is amazing. I wouldnt be surprised if someone doesn't make a few minor adjustments, claim it as their own, and take it to market. You've got something special here. Thanks for sharing it with the world
This is great, loved your video. Saw this concept a few years back in the RC world when Kyosho released the Drone Racer but they didn't do a good job of marketing it and it never became popular. What I like about your version is the fact that the components are readily available and you can upgrade/update and add your own improvements to it as new stuff comes out. Great job man, keep up the good work.
I hadn't seen the Kyosho before--adding more to your point of marketing lol. Thanks for the comment! I would love to see others build upgraded versions with their favorite components
Ten years ago, I pud an EDF on my quad and it worked but the quad was loosing 1m altitude when I activated the EDF and it was not going fast. I 'm happy to see your solution and I like it very much
I'm surprised by the carry weight it can hold. Looks really fun to fly, I kinda want one. It's amazing that you put all the files and code online so anyone can keep the R&D. I can't express with words how much I like your videos, keep em coming!!!
This reminds me of an rc hovercraft I once had. It “drifted” in a very similar fashion and was a lot of fun to drive. One downside was that it really only functioned well on smooth surfaces like a basketball court or the kitchen floor. This drift plane would be much more resilient to different terrains. Very cool idea, I think I just might have to build one
Really eager to see where this type of drone goes. Been watching the ejowerks one since it came out. Glad more people are working on this and pushing it forward.
My Resin Printer has been fun, but in order to eliminate creative limitations, both a filament, and resin printer should be in the shop… Going to save for an FDM 3D Printer (been thinking about it - now I have the creative motivation I needed ;) Hopefully will be building my own version of this, during the 2024 season! Thanks for posting this, and say hi to Josh Bardwell & Blunty! They're the channel that showed me this project. Happy Flying!
This looks so much fun to race against other people. Bigger laps than rc car, funnier and more flashy because of the drift, easyer to see and understand for spectators than quadcopter races, and i think the races could last longer than quadcopter's races
I’ve been working on dRehmflight for the last several weeks. I’ve fried a Teensy, I thought I fried my ESC but evidently those things are pretty hardy. I also encountered a set of fan blades running at several thousand RPM, and they will indeed happily slice your fingers into shreds. I have no particular interest in RC hobbies, but have thoroughly enjoyed the engineering and appreciate the incredibly detailed documentation and work that you’ve put into this. My end goal is to develop a heavy-lift cinema drone and implement some of the dRehmflight functions and features into other motor and sensor control systems. Thanks for all the fun!
Great work! Those irregular lines in your prints are caused by instability in the print bed. You can greatly improve print quality by PID tuning your print bed.
Nicholas Rehm Man, that is the most bizzare R/C idea i've yet to see AND I LOVE IT! I discovered your channel thru R/C test flight. You guys come up with some mind-bending ideas , thanks for the Brilliant code addition. I was watching Multiwii in the early days and really freaked out our elderly neighbours flying a Tri-Copter with LEDS flying like a madman thru the entire neighborhood all those years ago. Greatwork, My mind has been blown now!
Год назад+1
absolut perfect, this is insparation for all the Car/ Drone Pilots.......thumbs up👍👍💯
Nicholas, thank you for bringing me such amazing content. I love that you are so encouraging to your viewers to get going on our own projects and try to beat your designs. When i think about GOATS, i think of Michael Jordan, Tom Brady, & Nicholas Rehm
This is really great, it would really get people into the hobby. It will also only be a matter of time until a flight controller, height sensor, and software are available as a package. Then whatever cool frame to build or buy. It would be a little bigger than a 5 inch drone so you don't have to be a microsurgeon to build it. What a great concept!
You could make the bottom 5% of the throttle tilt the speeder forward without engaging the butt prop for creeping forward. Possibly blend it smoothly into the no-tilt buttprop speed mode, should give you better low speed control
This is really cool! I could imagine RC and eventually full-sized racing leagues built around rhis type of aerial, "drift car." Pod racing, here we come!
@@NicholasRehm Any reason why we can't scale this to carry a human with current battery tech? Electric cars have the batteries and lidar sensors needed...I feel like this negates a whole bunch of issues cars have now like rubber tires, weather making crashes etc. But yea, I want to race these in a league or something!! So my drone flys with a 23ms lag, would it be possible to fly one over the internet? How about a race of them?
A couple thoughts. For propulsion, I think it would be a nice symmetry to have both forward and backward acceleration accomplished with the same technique of integrating the pitch angle and pusher motor speed. This way, you can benefit from the lift motors when accelerating from a stop, and from the motor mount airfoils when braking. This would also seriously help the stalling effect you ran into on your speed runs. Worth the effort to command reverse on the additional ESC. It would also be cool to see even more bank integration in turns. However, the more you bank the more error is introduced in your height estimate since the sensor is pointed further from vertical. Are there any single axis scanning LiDAR sensors you could use to allow picking the "true down" measurement? If not, how difficult would it be to mount the sensor on a servo to always point down? This would be most impactful for high speed maneuvers in tight spaces where there are side obstacles. Also interested to see how much control you could get with one additional axis to set the desired height. I guess that depends on the effective range of the height sensor being large enough, but with GPS you could transition the altimeter from ground mode to fly mode and have a really controllable plane too. Very reminiscent of Daniel's ground effect projects.
Sensor fusion is your answer. Accelerometers tell you your "true" down. Normalize the axes and fuse it to your LIDAR to compensate the bank angle. No need for servos or anything else. Just mind your filtering :p
@@marian-gabriel9518 That's a fine suggestion but suffers from the same issue as the current implementation: if these are obstacles or significant terrain variation to the sides, the LiDAR sensor will report the distance to those obstacles instead of the distance to the ground directly below the vehicle. Imagine this extreme scenario: you are flying this vehicle towards the edge of a cliff and, upon realizing it, make a rapid banked turn to avoid flying off the edge. Even if you manage to stay on the cliff and not go over, when you are in the middle of the steep banked turn the LiDAR sensor could be pointing over the edge. The sensor would read the entire cliff height as your distance from the ground. Accounting for bank angle with a fixed sensor is only suitable for small bank angles. As the angle increases, you have to assume a smoother and more uniform ground surface, or add operating height for safety, otherwise the sensor may not read obstacles directly underneath the vehicle while in a banked turn.
@@haphazard1342 Yeap, but putting servos on that thing is not the best idea either. Weight and complexity. Can break easily. Better off to put two LIDAR sensors, one of each side at a 45° angle to the belly one...and use the accel to measure which one is pointing "more down". No moving parts, no lag till you get them pointed. The bad part is it's more expensive. EDIT: Also the LIDAR should also have a bit of a wide area where it measures...But if it's not wide enough to cover the amount of bank angle and choose the measured points along the accel. down vector, then use two, as I said above. Or make the width the sensor can see through, wider by making the body of the thing transparent on the area of the body of the craft where the sensor sits. Depends on how that LIDAR HW is implemented... EDIT II: With this (and assuming enough processing power to run three LIDARs) you can monitor all of them and make an obstacle avoidance mechanism, where you only choose the distance along the accel down vector for your altitude correction, and the rest of the LIDAR directions for banking away from obstacles. (Also I should add that I'm assuming a scanning LIDAR not a single point range finder kind)
@@marian-gabriel9518 Yes, that would also be an improvement. You could interpolate between the measured values for the sensors that bound "true down". However, seeing the size of the LiDAR module I think a servo would still be more compact. The speed of response does not have to be instant, because the craft cannot bank instantly. A standard gyro control loop would be plenty fast, and direct mounting the LiDAR module on a servo horn is not too complicated.
@@haphazard1342 Sure, you can do that, but you have to keep in mind that the sensor mounted on the servo still has to be both protected, so inside the fuselage, if you will, and also have a sufficient cutout in that fuselage to allow it to move and "see" and at that point you are exactly describing a scanning LIDAR which is already integrated as a standalone package, that's my rationale behind it...and it gives you potentially a larger viewing area or field of view, is faster (so you can use more filtering and get more accurate measurements). For a simple, approach your idea is the easiest and fastest to implement, mine is more expensive and involved, but I still think, purely from a performance and cost/benefit viewpoint, that it's better to go to an actual (meaning scanning) LIDAR, but at this point it's just a matter of preference/ cost and ease of implementation. EDIT: I like how this discussion feels like a HARA/FMEA engineering meeting :)))
To prevent dipping / generating false height measurements when tilting the craft. You could add more LiDAR sensors at an angel and find the lowest value to use with the flight controller.
Wow so rad… that could be a viable product. Could you put a couple cameras facing down to hold position and gauge speed alike also helping it turn with out drift? It could have a drift mode for expert mode.

I already want to figure out how to shrink it to something you could use in a building.

Ten years ago, I pud an EDF on my quad and it worked but the quad was loosing 1m altitude when I activated the EDF and it was not going fast. I 'm happy to see your solution and I like it very much
This looks ready for retail.
The most sensible build I've seen you do.
This is such a cool project! It gives me RCTestFlight ground-effect vehicle vibes.
I really appreciated your applied physics analysis and how you illustrated your solutions..Solid!

Love watching the hobby growing with great ideas like this 👍
EPIC! Nice work, Nick!
Now waterproof it and make it a drone, car, and submarine! Haha, but for real I love this idea! Makes me want to buy one
Waterproofing would be a fun side project--would give me the confidence to fly this thing over water haha

You have to make it in to a landspeeder!!!!
nice to see someone actually doing quality projects on YT. PS try big side panels. will act as forward stabilizers

Have you considered a jump button for short but high obstacle, that the lidar cannot catch in time?
That'd be cool and easy to implement with another channel!
Holy crap, that is an awesome idea.. This would be like integrating Mariokart into it..
@@NicholasRehm I would absolutely love to see that!!
You just made my dream come true, I hope for a bnf version to be available soon
