Manuals
Warnings
Configure power components carefully and consult the vehicle manufacturer for advice; incorrect assembly can overload the motor and cause damage. Fasten wiring securely to avoid control problems. Never run at maximum power without a pinion gear; very high RPM without load can damage the motor. To prevent magnet loss, keep the motor casing below 100 degrees Celsius (212 degrees Fahrenheit).
Details

The QUICRUN 3660 SL G2 sensorless brushless motor uses a ribbed black can with three phase wires for straightforward ESC hookup in 1/10 builds.
