separate BEC for retract servo?
I'm using 3s LiPo but don't want to run the retract servo on the SBEC.
Thinking of making a simple BEC out of a 7805 voltage regulator for just the retract servo.
This should not get hot for the occasional use the retracts see, may have to use a small heatsink. If the servo stalls the regulator should protect itself (overcurrent or overtemperature) and not cause a problem for the rest of the system.
What do you think?

It should save the BEC from excessive loads.
Don't forget to filter the 7805's output with a cap. (.1uf is big enough to stop internally generated oscillations). The 7805 can draw allot of idle current if it oscillates.
