This is the entire big block motor and mounting plate conversion for HPI micro RS4.

This motor is specifically designed for the Team LOSI Mini-T. It has increased motor output over the standard kit motor which means greater torque and higher top speeds.

Handwound Flatliner armature for more efficiency and power. Up to 4 times longer brush life. Dual shunt brushes. Dual ball bearings. FB9 magnets offer very high resistancet to demagnetization.

This Monster Big Block motor has longer magnets, longer high torque rotor design and single winds for maximum low end power. Motor uses big brushes for longer life and more power. Torque ring increases magnetic field by reducing magnetic flux loss.
