1. We need to modify our servo so that it can fit flush against the back plate.

2. To do this, we’ll start by sanding off the black clip closest to the servo horn.

3. Use your Dremel tool with either a cutoff wheel or a sanding wheel to cut off the black clip.

4. Next, we will cut a slot so the wires can run out the back of the servo and not the top. Remove the four screws on the back of the servo, then remove the back plate. Elongate the existing hole with your Dremel tool using the cutoff wheel.
