Solarbotics RM2 (high-power motor for GM2/3/8/9)
This high-power brushed DC motor fits in the GM2/3/8/9 series of gear motors, offering approximately 3 times the speed, twice the torque and quadruple the power-draw! Retrofitting the gear motor is easy – just remove the motor retainer strap, transfer the pinion gear, and reinstall – that’s it! This motor is popular for souping up anything driven by the more standard 130-size motors, such as flywheel NERF guns.
For a generic alternative to this motor with the same size and nearly identical performance, see our Brushed DC Motor: 130-Size, 3V, 17kRPM, 3.6A Stall.
NOTE: Be forewarned – we’re not kidding about the increase in power requirements and output! This motor eats batteries quickly, and it has a relatively short lifetime at high voltages. For example, in our tests, this motor was able to run continuously at 6 V for approximately five hours before failing.
