Gyro Unit Set For Kyosho Mini-Z RC Car Parts Description: Weight: 1g Wire Length: 80mm This Gyro Unit plugs right into the main board of your MR-03 & will help you keep your MR-03 under control. The Gyro Unit will automatic correct of steering & throttle. Basically it will keep the steering aimed to the global direction, so say your rear tires loose traction & the chassis come to an angle, this will counter steer for you faster than humanely possible. Very cool, & really impressive having the car stable like if it was following a rail on low traction surfaces (wood, tiles). Package Included:1 XGyro Unit Set
