I Want to Build a Go Fast RC !

[Overdriven]

Funny thing about Indy + F1 cars, if you need more traction in a corner, go faster. While more speed = more downforce is easily understood, try telling your brain to press on the gas more in that situation!

I'm sure there are formulas Indy + F1 teams use, but they know how much downforce the car makes, spring rates, etc. Doubt anyone knows exactly how much a particular rc body makes. I'm sure someone will pipe in with a useful setup though.

I wonder if you could use something attached to the chassis to see how much the suspension compresses during a run. My first thought is clay, that would wear if it touched pavement, but I'm sure someone could come up with something better.
