Suit for 1/10 RC Crawler Axial SCX10 AX10 Wraith.<br><br>Learn More: Many 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 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- mission to the "shaft-induced effect" by adding another mission gear set on the at the same mission ratio that allow one shaft rotates in the oppisite direction, thus counter actions exerted by front and rear output shafts being counteracted mutually.
