Sorry my short post.
For race, we only run at 17.5 and no timing / boost. (Beginner Class) So everything depends on gaering.
I will run at a speed passion motor MMM V3 motor.
(Have read of it would be good without timing.)
ESC I do not know quite yet what I want. But it has probably not so important when I do not use timing.
Here are a few pictures of the track I run on.
