The SG20 Series Servo Gearbox (3.8:1 Ratio, 663° Rotation, 1794 oz-in, 0.53 sec/60°) utilizes the Hitec HSR-M9382TH Servo that has been programmed to rotate 7 turns while retaining positioning feedback.

Given the 3.8:1 ratio of this gearbox, the large aluminum gear will spin a maximum of 1.8 turns at a little more than one fourth the speed of the original servo, but with nearly four times the torque.

The 1/2 inch diameter stainless steel shaft of the Servo Gearbox is supported by a pair of 1/2 inch ball bearings and held in place with retaining rings above and below the bearings so that it can withstand loads from any direction.

The Servo Gearbox is easily attached to the Actobotics Channel, given its overall width of 1.32 inches (to match the internal width of the U-Channel). For those of you installing in an R/C vehicle, the 585506 bracket is a popular choice as it creates ears to mount the servo gearbox down to a flat surface.

This model is programmed to allow the servo to rotate 7 turns, you can easily adjust the parameters of the servo using the Hitec DPC-11 Servo Programmer and BLDC Ver 3.1 firmware. You can fine-tune the rotation to fit your application, or even program it for continuous rotation.
