Wingracer convinced me in this thread that I have much to learn about race car vehicle dynamics. Since this discussion related to the scale down of 1:1 to 1:N, N > 1, I am posting up a book reference mentioned on another thread that appears to be a great resource.
Race Car Vehicle Dynamics
This page reveals the general approach to engineering simulations:
1. tire model
2. lateral and longitudinal acceleration
3. lap time simulation
4. vehicle dynamics simulation (transition handling)
My own interest is to greatly simplify these ideas for PC simulation to support teachers in technology classrooms, and to perhaps deliver the same tools to help newbies or experienced RC racers get "good enough" engineering simulations to improve their driveline optimization knowledge and track tuning process.
