All of the electric retracts we have worked with have an over-current protection circuit that stops the motor in the event that the retract is jammed. This prevents a brown out from the current draw (which is less than 1A anyways when stalled before it shuts off). Considering that a single HS55 servo draws 750mA when stalled, this doesn't seem to be much of an issue using the receiver pack for powering these retracts. Now, having said that, we have not worked with the LARGE electric retracts, which surely draw more current. Isolating the retracts so they using their own power source is a simple matter of just using the GROUND and SIGNAL wires connected to the receiver, and the POWER and an additional GROUND going to a seperate battery.
