I agree with previous suggestion that
1. read the manual! (NO REPLACEMENT FOR LEARNING SOMETHING FOR YOURSELF)
2. ask fellow racers at the track (despite competition, there is always someone there to help you)
3. smile <-- there are some losers at the track who will give u sh*t, and teach u at the same time, when facing those people, remember to smile and thank them, because their knowledge is yours now, and u don't have to deal with them anymore.
4. smile <-- there are some losers who will not help you at the track and give you sh*t, for those people, remember to thank them, then lap them while chuckling to yourself.
5. smile and bring your wallet to a hobby shop <-- this is what i use to do, get it done at a model shop once, let the pro at the shop show you how its done, and after that, never have to ask again.
Hope that helps, I know it was not "red wire to positive" type teaching, but it should help you get a head start on anything else you would like to learn about electric racing.
