This is an optional Lynx Heli 0.5Mx3.17mm 300X/CFX Pinion Gear Set, including one 11 Tooth and one 12 Tooth pinion gear. Looking at the 300X/CFX pinion gear, Lynx discovered how quickly the brass material would cause the pinion excessively quick wear. Using their material experience in pinion production, they created a series of straight tooth Carbon Steel pinions, to assure the best wear resistances flight after flight, without compromise and comparison.

3.17mm diameter motor shaft
