40mm Quick Change Mount, designed by Anthony Vaccaro. Designed to speed up swamping of a motor during a race or if your just tired of trying to remove the front screws on your motor for maintenance. Once the coupler is loosened, the motor can be removed in less than a minute. Normally racers would have to remove the front screws which could take a few minutes and more importantly, once a motor is removed in a conventional mount, the motor angle has to be realigned. With only 4 screws the motor is removed, while maintaining the motor angle. Also features clear access to the front motor vents to allow maximum cooling.
