Dedicated battery for sailplane retract servo
Sharing a handy diagram from some years ago. When rigging a large scale sailplane, it's best that the retract servo have its own dedicated battery to power the servo. That way if anything gets hung up, the main receiver/control surface power is not compromised.
Essentially, the retract servo sees the ground and hot from the battery and the ground and signal, but not the hot from the receiver.
Also, here is a link to John Derstine's excellent article on the subject:
