so I just got a new fancy servo for my summit and I was going to try it out for the first time, my truck is running with an LVC and two 7.4v lipos, the motor was not connected to the esc, so this is what I did...
1. I turn on the transmitter
2. I plug one lipo in
3. I plug the other lipo in
4. zap! part of the esc cord went up in smoke
I didn't even turn the esc on, when I plugged the other batt in it fried this wire
any ideas why this happened? is it because I plugged the batteries into the esc without having the motor connected? thanks for your help
