for high power system it would be nice to have no dc current ways from the autopilot to the drive and servo system.
A good way to eliminate EMC problems will be the use of opto couplers also for the servo counter.
One for count and one for reset.
Another free GPL autopilot project have also isolated the Servo systems with opto couplers to.
Another good idea is to isolate the RC Receiver by a opto coupler to.

I am working on a board that has a separate 12V and 5V switching regulators for servos and an input for a battery for an autopilot and servo battery backup. Is this something that anyone else would want? Vin for the board is about 50V This would allow for the autopilot to be used for much larger planes.. is this something anyone else would be interested in?

I think the onboard regulator be changed for a 3.3v @ 2A or more output with the parallel removal of the linear 3.3v regulator. Even if the 5v regulator is upgraded to a high amperage one i don't think that it is wise to run high current and noisy lines from servos inside the autopilot's pcb. I keep the high current path for the servos well outside the autopilot's pcb.
