I've tried it both ways on mine. Works both ways with my ESC.


Some ESC's need that red wire. try putting the red wire back in the ESC connector with the BEC in the system, and see if it still has the problem.

MY ESC has a built in 2A BEC, but that was not enough for my 3 Hitec HS-65MG's, Hitec HS-81, and GY-401, the servos all jittered and the ESC got very warm just during programming. So I installed the CC BEC and now everything is good, no jitters.
