On my 1/10 cars I run direct wire bullets to reduce both resistance and weight, these are key factors for stock racing to help get a slight edge on the competition... if you decide to go with bullets, be sure to reduce the length of the connector so you can't accidentally reverse the polarity, all it takes is a split second to fry any ESC.

On my 1/8 cars I just use Deans compatible connectors, mod cars don't need to mess with the above nonsense.
