1,700+ oz-in. of torque and unlimited rotation from an inexpensive 1/4-scale servo....easily done with the new SPG805A-BM-CR Servo Power Gearbox. The structure is machined from high-strength 6061-T6 aluminum. The hardened 3/8” stainless steel final shaft is supported by dual ABEC-5 precision ball bearings that not only allow extremely smooth operation but can also support over 200 pounds of vertical and horizontal load. By transferring the power directly to the mounting hub through the spur gear, no rotational slippage will occur. With four optional gear ratios, you are sure to find the right combination of power and speed for your project. All gear ratios can easily be changed. Mounting various attachments is simple with the four 5-40 tapped holes in the aluminum clamp hub. Mounting tabs are .125” thick. Build your own custom SPG805A-BM-CR by choosing the ratio you need in assembled or kit form (full instructions included). Patented

* We highly recommend purchasing this unit assembled by our factory. If you are not accustomed to using a soldering iron or handling delicate parts, please order this product assembled ready to plug into your receiver or servo controller. It is money well spent. Thanks

Given a 1500usec PWM, rotation will stop. Any signal between 1505usec to 1100usec or 1495usec- to 900usec will make the servo rotate variable rpm to the PWM signal. IE: A signal closest to 1500usec, the servo will rotated slowly. A signal further from 1500usec the servo will rotate faster.

Four 5-40 tapped holes in the mounting hub allows for various attachments.
