To compliment our Scorpion HK series Helicopter motors, we are now offering Pinion Gears in the popular Mod .5 size that are used with most 400, 450 and 480 class electric helicopters. These pinions are designed to fit any motor with a 3.175mm shaft (1/8 inch), and come with an allen key set screw.
This package includes one 10-Tooth pinion gear and one set screw.
What is the outside diameter of this gear, and also the width?

The outside diameter of this gear, at the base, is 6.15 mm (0.242 inches). The overall length of the gear from top to bottom is 12.0 mm. The useable part of the gear, measuring down from the top, is 7.5mm. This will allow for a main gear that is up to 7.5mm thick and still get full engagement of the gear teeth without hitting the bottom area where the gear starts to flare out.
