Serviceable Servo Arms

[StephenCarlson]

There is currently no way to remove a servo arm/horn without removing the servo from the wing. A shaft/ramp should be subtracted from the wing such that a screwdriver can reach the servo output shaft.

I'm considering renaming this Issue or merging it with a new one: Completely Removable Servo Trays. Spending an hour just to remove a dead servo from the wing, while tediously trying to chisel out hot-melt adhesive, is getting really old. This would add complexity to the wing design, but would allow for any size servo to be placed with a unified tray design.
