I am kind of proud of the radio install so I have posted a picture here. The battery is underneath the rudder servo and the receiver is velcroed beside it. Everything is pushed as far back as possible since the plane ended up nose heavy with the 50SX on it.

Note that the rudder servo is closer to the wing than the other servos to allow clearance. The pull cables are crossed in the fuselage and there is some tubing to stop it from rubbing on the last fuselage former.
