Smallest and Lightest with No Compromises! Blitz Lite motors are short, so let's keep this description short too. Blitz Lite is shorter and lighter than any other 6mm shaft beetleweight drive gearmotor on the market. To accomplish this, rather than modifying an existing gearbox, we designed a fully custom one from the ground up and invested thousands in tooling to bring it to life! Highlights include: D-Shaped motor shaft for no pinion slip, ever Durable one-part steel ring gear and faceplate, 20mm diameter Dual ball bearing shaft support (no soft bronze bushings!) Billet 6mm diameter hardened 4140 steel output shaft 3X M3 face mounting threads All metal gears, 2-stage 29:1 ratio High-performance brushless motor for 3S-6S operation Custom motor base to minimize length and maximize reliability
