We actually corner at a much higher speed to what they could ever manage so theoretically our wings, or any aero package come to that will have a greater effect.
I say go for it, but check the rules first.
Scale speed is a myth, an RC car is simply a very small car travelling at 20mph. So the only aero effects you get are those of air travelling over a wing at 20mph. Not a whole lot of pressure, but yes it can have an affect on something weighing only 1500gms. Watch how those little electric park flyers take off and fly at very low speeds, 10-15mph perhaps, and they weight only a couple of hundred grams.
Most current RC body designs develop downforce through drag rather than aero. Probably 1/12th/Pro-10 are the only cars that actually make any use of air pressure rather than pure drag when you cut the rear of the body out.
Another thing to consider is that a small vehicle is very imperfect in terms of the air flow. RC cars don't tend to have the flat enclosed bottom typical of road and race cars so flow is a mess.
That German Tamiya F1 looks fascinating though, surprised it is legal for a race class with all those mods!
