Not sure yet.
Well, I don't know the dimensions of the track yet. I have only looked it over once. If I had to guess I'd say 60-80ft straight.
as for motors we are to run 21.5t but no set motor and I think blinky on the esc. I have a speedmind 21.5t and a Novak ballistic 21.5t (these are 0 timing I think)
I will use 3.5 to 4 as a starting point. I want fast but controlled as it's been 3 years since I drove the cars.
