This is a protector to prevent damage to the aileron servo arms on a T-28D Trojan RC airplane I recently purchased.I did not install the tricycle landing gear on the plane since I will land on grass most of the time. This exposed the aileron servos on the underside of the wing to damage during landing.This is MakerBot at its best: need a part the manufacturer doesn't make, no problem design your own and print it.Note: this design has a slight curve at the front to conform to the wing leading edge. Adjust it for other wing shapes.
