Try our new Rhino Gear pinions! No more days of landing after a flight of EXTREME 3D to find your pinion teeth looking as if they have melted away, or snapping a pinion in-flight due to improper hardening!

A Rhino Gear pinion could be the last pinion you will ever purchase! They are machined to exacting specifications from high quality carbon steel and then Ultra-Hardened for lasting durability and outstanding strength! Maintaining these tight specifications means less gear noise and less wear on your helicopter’s main gear.

Modulus .6 and .7 Rhino Gears have a 4mm set screw to give awesome gripping power on the motor shaft! No need to worry about pinion slip, even with the most insane power systems driving your helicopter!
