Noob question here, I guess.
Can I safely remove the ground wires as well as the red wires from the ESCs to the APM, using just the 4 signal wires?
The APM is powered by a power module, the receiver is powered from a “TURNIGY 5-7.5A (8~42v) HV UBEC” and the FPV gear is powered by a 12v regulator and filter.
The ESC are TBS 30a Bullet Proof ones. It is all powered from the same LiPo.
