I am worried about that as well. Since this is the only electric I have, I ordered a $12, 30 AMP, no name ESC\BEC.
I tried a few things to tet the motor without a ESC:
[*]Measued resistance between the leads and they all have the same resistance (.6 ohms).[*]Tested each lead for a shorts against the case.[*]Spun the motor and touched the leads together and it got harder to spin.[*]Set the volt meter to measure AC voltage andspun the motor by hand.Imeassured the votage accross each lead. I got the same voltage on each (about 3 volts)[/list]So farthe motorlooks ok before I hook it up and burn out the new ESC. The ESCshould be here friday and I will know for sure then . I wasthinking of spraying it with that stuff I seen on TV (where they put a screen door on a boat and spray it). Is thatCorrosionX ?
