Installation Diagram

Always install wires as illustrated in the diagram, use high quality insulated wires and solder with high silver content. To prevent damaging the motor and ESC PCBs, use a temperature regulated soldering iron and avoid prolong contact of no more than 5 seconds.

The hall effect sensor is compliant with all major race sanctioning bodies (refer to Motor Specifications Table) and is compatible with all sensored ESC that follows the same standards. Be sure to periodically check your sensor wire as a loose or damaged sensor wire may impair the performance of your motor.

For sensored ESCs, always connect the sensor wire before turning ESC on as motor may become damaged, our warranty policy do not cover motors damaged due to the absence or incorrect installation of the sensor wire even if ESC manufacturer suggests you may do so.

There's no need to regularly fully disassemble your motor for maintenance as the Taichi Motor was designed with minimal need for maintenance. Should you need to partially or fully disassemble the motor for bearing lubrication, parts inspection or a regular rebuild, please refer to the exploded diagram.

To disassemble motor, loosen and remove the three outer screws on the top end plate of the motor using a 1.5mm hex wrench. You may then gently remove the top and bottom end plates allowing access to the rotor, to adjust motor timing simply loosen the 2 inner screws on the timing ring plate about 1 turn out and adjust the timing ring to the desired timing position and make sure you retighten the screws afterwards.

Bearing Maintenance - be sure to periodically check and lubricate bearings as it is the only component which requires regular maintenance.
