RCBENECO Metal Reverse Transmission Gearbox for 1/10 RC Crawler Car Axial SCX10 90027 SCX10 II 90046 WRAITH UpgradePackage List:1 * Reverse Transmission GearboxMany vehicles are equppied with only common gearboxes with only one output shaft shared by front and rear axles; in this case, the shafts of front and rear axles rotate in the same direction and exert an obvious counter action on the gear box as part of the vehicle body; therefore, the vehicle can incline toward one side under counter action while moving forward or climbing, and the larger the output torque of the shaft, the larger the counter action, the more the vehicle body inclines to one side. The vehicle can incline toward another side when it moves backward. Counter-transmission aims to eliminate the "shaft-induced effect" by adding another transmission gear set on the gear box at the same transmission ratio that allow one shaft rotates in the oppisite direction, thus counter actions exerted by front and rear output shaft
