That's pretty awesome

Should have asked Mark Webber to guest star as your test driver

man this sort of stuff could change the landscape of competitive RC racing. how cool would it be to see an openly engineered RC world championship? custom bodies, chassis, aerofoils etc.

Easy workaround for the flipping... Set the actuator to the "no downforce" position by default, then have it go "full downforce" if either brakes or steering is inputted. Either that or the even simpler route Set the actuator to "full downforce" at all times except when the throttle is pressed have it set to "no downforce"

Great to see you back, would love an indepth video on thermals at some point, similar to your first (or early) video. I notice Arrma are fitting heatsinks and fans to some of their range out of the box these days.

I love this channel. I'm not this smart, so I have to get by on my willingness to break my cars and just lean into being the idiot I am. If I was smart like this guy, I would probably be attempting similar AWESOME stuff like this. Great video! I hope you get a million subs soon.

You should have way more subs for this level on content

I'm so glad you're back!

i already did this to my vendetta it works!

Curious that you saw such impressive results with a simple scaling without taking into consideration the Reynolds number effect that downscaling would impart. Perhaps it was somewhat offset by the inclusion of the 3rd wing. Fascinating video of the wing flexing under aerodynamic load! Seems that a variable front downforce device would prove to be very valuable.

And just when I thought KZfaq betrayed me. You came to my rescue.

yay finally another video

Nice

But anyway, to be on topic to the video, have you explored unsprung aero? That should quickly solve your squatting problem, plus it lets you run softer suspension all around for better mechanical grip at low speeds. Also, RIP GT car body and aero. Thanks for the video on DRS.

Very cool.

You're inspiring me

Getting it do toggle automatically between high and low speeds would be neat.

Even looks like a CRL

Time to get more cunning. Dynamically adjust the spoiler angle so that it maintains a constant squat on the rear suspension regardless of speed.

That's awesome. You sacrificed the RC car for science. I can't believe how quickly the car generated enough downforce to lift the front end like that. How fast do you think you were going? I think it's a lot harder to regulate aero downforce at the RC car scale. After watching your video, I ran my RC car thru some CFD simulations and my car will launch into the air like that with ~4 degrees of pitch change, and I have a giant opening behind the front wing for air flow not a flat floor. 4 degrees of pitch is huge for a full size car but for an RC car this is just a small bump around 20mm. I don't know if you found this but multi-element wings tend to be less pitch sensitive, which probably made your situation worse because as the car tilted the rear wing was still making a good portion of it's downforce.

Just because something is small doesn't mean its not gonna function !

Incorporate F-Duct, too, please in your car(s)

Really cool!... another great video. I've often wondered if a front splitter with this tech, attatched to a gyro would keep the front from lifiting if set right..?? Would create more downforce if car was constantly trying to lift up but if normaly level and just fighting the odd bump, maybe it would be good.... also if working with the back one, so had extra downfoce all around for coners and none for the staights... just a thought but I'm no expert.. independant sides would be another step so could add downforce to the inside through corners..

Nice. Have you considered to try something similar to the active aero like the Pagani Huayra BC with both front and rear aero flaps that also help turning.

0:19 so, you made a mercedes? Edit: oh, you already said it in the video

On such a small light weight vehicle, wouldnt simply adding ballast weight result in the same traction advantage but without the added aero drag or a wing?

I feel like if the whole car had a lower ride height you wouldnt have that flipping issue.

Did anyone mention rake? Or shock limiters?

You have plans for underside down force or an rc delta-wing clone ?

How did you determine the angle of rotation of the servo?

>24fps >Filming a small, fast moving object **pukes** Please at least use 30. I can give you camera settings to make any frame rate for any type of shot on most cameras look amazing. The main thing you gotta do is ignore the 180-degree rule and instead select a shutter speed in the 1/40th to 1/60th of a second range, and set shutter priority mode if you use auto exposure. You may need to buy an ND filter in order to shoot outdoors in bright situations after locking down your shutter speed like this, in which case, if you only want to spend money on ONE, get an ND16 filter, but if you buy TWO get an ND8 and an ND32. Also, avoid decimal framerates (23.976/.98, 29.97, 59.94) and instead use full frame rates, or at least never get them mixed up in post without properly re-encoding decimal to full. Lastly, avoid non-intra-frame codecs and instead use only all-intra-frame codecs such as ProRes or if you use a Sony camera XAVC S-I not plain S or X. They preserve motion accuracy better AND edit faster/easier on your PC.
