Can I use this motor for drift events?

No. This motor is tuned for high speed and torque on the track and is not optimised for the sustained low traction control used in drifting.

What else do I need to install it?

You will need to solder the motor leads and fit appropriate connectors. Pair it with a compatible Volac speed controller and ensure your pinion and gearing suit the RPM range.

What should I check after each race?

Inspect solder joints, motor mount security and bearing condition. Monitor temperature during runs and allow cooling between heats to protect performance.
