I'm still reading and planning this winter's UAV, which will most certainly operate Arduplane.
I see that usually APM gets its power from the BEC off the ESC, via the throttle pins. The plan I have for my plane is to use a separate BEC to drive the servos at 6V and offer a higher amperage so that they don't brown out the system.
That brings two questions to mind:
- How do I power the APM with a BEC? Will plugging it into the receiver still power the APM & servos? I know there's a separate pair of pins for an alternative power source (like bench testing), but from what I understand, power from those pins isn't passed on to the servos.
- And will the APM tolerate 6v if I want to run higher voltage to the servos?
