## Description

**Note:** These are cheap, high-performance motors, so Pololu have notably low lifetimes, especially at higher voltages. Think of them as fireworks.

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](https://core-electronics.com.au/brushed-dc-motor-130-size-6v-11-5krpm-800ma-stall.html), such as flywheel NERF blasters.

**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 Pololu's tests, this motor was able to run continuously at 6 V without any load for approximately five hours before failing.
