| 7 | This has the effect of increasing the torque by a factor of 3x while decreasing the maximum speed and overall angle by a factor of 3x. Therefore a full rotation of the output horn will result in a 120 degree travel of the larger 48 tooth gear. For high torque, high axial or radial loads, use the external gear bracket assembly. Center distance when using these two gears is 1.00 inches. | ||

| 13 | This has no effect on gearing, rpm or overall angle. Having both gears on the LSS creates a second driven axis. A 1:1 configuration can be used with the gear bracket where high axial or radial loads exist. Center distance when using these two gears is 1.00 inches. | ||

| 38 | Edit | ||
| 39 | There are various ways to mount the gears to the servo without using the gear bracket. Below are just some examples showing gears mounted with and without the gearbox bracket. Note that the gearbox bracket can be mounted on multiple sides of the servo. The gearbox bracket is used largely for applications with higher forces (axially and radially) and higher torque. |
