To compliment our Scorpion HK series Helicopter motors, we are now offering steel Pinion Gears in the popular Mod .6 size that are used with most 500 and 550 class electric helicopters. These pinions are designed to fit any motor with a 5.0mm shaft, and come with a set screw.
This package includes one 15-Tooth pinion gear and one set screw.
