Having people around that will know the motor better can help you tune it and have a fun day. There is nothing more frustrating than having a bad tuned motor and not knowing how to fix it on your own. Good luck with your find.
While part of me agrees with you tom2tone, the other part says how hard is it to surf the web to find the answer to any of your questions? He found this forum didn't he? if your into rc cars for a quick fun fix, that's one thing, but if your in it from a hobby stand point, then you learn via trial and error and from getting tips from other hobbiest. ie forums, hobby shops and racetrack where your hobby takes place. if your from the "now generation" then this hobby is probly not for you!
