Epoxy Board Servo Arm sets for 50cc Plane

A servo arm set in epoxy board for a 50cc class aircraft. At this size the servo loads are still high enough that a laminated arm is worthwhile over a moulded plastic one, and buying the set keeps every surface on the model using arms of consistent geometry.

Consistency matters because the arm length sets the mechanical advantage between the servo and the surface — different lengths on different surfaces mean different servo loads and different deflections for the same servo travel.

Confirm the spline count and hole spacing suit your servos before ordering.
