GForce Rev Limiter for brushless speed controllers
Coming soon from GForce is the Rev Limiter module to limit the maximum RPM of electric brushless motors. Looped between the motor, controller and receiver the device limits the maximum RPM of sensored brushless motors in four steps between 10,000 and 17,000 RPM. Micro switches and status LEDs help to check the setting, making the module ideal to equalise the performance of brushless motors for entry level and stock racing classes. The 2S LiPo-compatible Rev Limiter comes in a lightweight case, it measures 22x15x10mm and comes pre-wired with universal connectors and including a sensor wire.
