I have a BEC on each of my 4 ESC's and no servos or anything that really needs 5v besides the controller itself.
Why is it that the controller cant draw its power from the BEC via the esc leads like other controllers do?
why do we need a separate battery for the arduino?
and i know the Arduino has a voltage regulator, and you CAN run it directly off your main motor battery... but why do that when you have a plentiful supply of 5v already created and waiting?
(and i sometimes run higher voltage than those lil regulators might like, so i would rather avoid that.
I was wondering if there is a reason i couldn't solder a wire between all the red ESC pins and all the black ESC pins on the shield (from below) and feed them into the arduino's power jack?
