Compatible with the RoboClash Kits. These 16mm Silver Spark Gearmotors have been the gold standard in combat robotics for many years! Physical Specifications Gearbox Length: 12.7mm (0.50in) Motor Length: 28.7mm (1.13in) Gearbox weight: 29g (1.02oz) Motor weight (no gearbox): 17g (0.60oz) Gearbox Diameter: 16mm (0.63in) Shaft Diameter: 3mm (0.12in) with flat along length Shaft Length: 38mm (1.5in) Mounting Holes (2): #2-56 spaced 11mm (0.433in) apart NOTE: do not use screws that protrude more than 2mm (0.078in) into gearbox Motor (Mabuchi FK-050SH-13125) Specifications: Operating Voltage: 3V - 18.5V (>10V decreases motor life) Nominal Voltage: 6V, but most commonly run at 11.1V. (14.8V runs fine but support the shaft because the gears are taking more abuse.)
