	SPG805A Standard Rotation

1,715 oz-in.

0.28 sec/60° (2:1 ratio)

1,700+ oz-in. of torque from an inexpensive 1/4-scale servo....easily done with the new SPG805A Servo Power Gearbox. The all new 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 up to 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 .250” thick. Build your own custom SPG805A by choosing the ratio you need in assembled or kit form (full instructions included). Patented with other patents pending


	* 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

		Normal operation of most servos is 90° but they can operate to 180° when given a pulse signal ranging from 700usec to 2300usec. Since most R/C controllers cannot generate this wide of signal range, you will need to purchase our servo stretcher for 180° operation.


	Shown with 8” Dual ABS Arm






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