on a side note: when I started in brushless I fried a very expensive Hacker setup, several hv-maxx setups and countless nimh batteries. For you're first brushless setup you're really not doing too bad. Wrenching and failures are part of the hobby. Think top fuel dragsters that need to rebuild their motor after each run.
