noob e-revo?

A BEC or UBEC is used depending on the set up of your RC. I take it your using all the stock Emaxx stuff correct? What batteries and how many cells? Most or all ESC's have an internal BEC. They can only handle so much from the batteries you plan to use. I have an Emaxx tranny with a MM ESC. I plan to use 2s2p Lipo's ran in serious. I have to wire in a UBEC to handle the Lipo's. The internal BEC of the MM can't handle 4s. I hope this helps.
