This motor comes in a nice case and is manufactured by Solink, an OEM for motors for a long time.The main feature of this innovative motor is the unidirectional bearing, which removes the need for an anti-reversal latch. Removing the ARL reduces noise and allows for a more crisp response. 35,000 RPM is a higher than average speed and pairs well with balanced gears and even some lower ratio gearsets. Unlike traditional potentiometer screw adjustments, this motor features a simplified speed regulation system. Users can easily adjust the speed, changing it by 20% with a literal flick of a switch. Features a motor tower with enlarged bearings and a unidirectional bearing.Important installation note: Do a test fit with the motor grip plate before placing the motor in the grip. If the motor plate makes contact with the speed regulator switch, then remove material from the grip plate until there is clearance. Direct contact with the speed switch could break it!
