This compact, lightweight unit is equipped with a gyro sensor system and when it detects the car beginning to slide, it quickly applies counter steering to prevent spins and maintain the car's stability. This is especially helpful when driving rear-wheel drive cars, such as the F104 and RM-01 chassis machines, or driving on slippery track surfaces. The counter steering range can be adjusted and sensitivity may also be adjusted by your transmitter when a 3-channel R/C system is used.

Note: Gyro systems are banned from use in organized competition in the United States from leading sanctioning organizations. It is also banned for use in the Tamiya Championship Series. The item is recommended for hobbyists who are not racing in such events.
