The GPM 40CR Steel Motor Gear 29T is specified for durability and stable power transfer in upgraded drive systems. Manufactured from hardened 40Cr carbon steel, the component resists wear more effectively than many stock gears while maintaining accurate engagement. The design includes a D-shaped motor gear bore, a 1.0mm module and a total thickness of 15mm for correct compatibility. Dual kimi screw fixation enhances mechanical retention, supporting reliable operation in demanding RC use.
