 Large gear reduction in compact space.
Worm gear design allows a large gear reduction ratio to be fitted into compact space that also delivers high strength and easy maintenance. The small number of moving gears also minimizes the potential for trouble and results in greater reliability.

 High-cost special motors are not required.
The large gear reduction ratio works fine with the standard power motor with output of 20 to 27 turns. In addition to avoiding the high-cost of special motors, highly efficient and powerful torque delivers excellent low range control.

 Self-locking function doesn't require special ESC.
No special ESC is required as the one-way drive transfer of the worm-gears prevents reverse rotation of the tires so the tires lock automatically when the throttle is released. This also provides powerful stopping effect on steep slopes and works well with standard speed controllers. A special rock-crawler ESC with a drag brake is not required.

 Minimizes torque twist
 Large gear reduction ratio on the axle side enables a transmission with smaller 1st gear reduction to be positioned directly behind the motor. Torque load on the propeller shaft is reduced and this allows torque twist (characterized by the tires floating up) to be minimized and traction to be maintained for decisive rock crawling performance.

 Makes full use of suspension stroke.
The slight angle of the propeller shaft with the machine in a 1G state (resting on the ground at normal posture) allows plenty of extension for the suspension stroke. In addition, the minimal refraction angle of the universal joints produces higher drive efficiency and controls loss of drive power.

 Reduces interference from contact
Propeller shafts can be offset on top of the front - rear axle units to provide greater ground clearance and therefore reduce the risk of contact with surface objects.

 Ultra-tough worm gear unit
Tempered steel results in super-strong gears. Heavy-duty specifications have the durability to withstand severe kickbacks.
