I then marked the screw holes with a fine point marker and used a heated pin to "burn" the servo mounting holes in the plywood brackets. In went the servo afterwards with the screws. Next step was to put the control horn in - I used the supplied bolt and associated hardware. I used a little Loctite on the threaded rod to ensure it stayed in place without backing out. The next step was to make up the control rod using the supplied ball link clevises. Everything is the right size and no cutting was needed. The only additional time taken was to ensure the rod was the right length and the stab was "flat" without any up/down trim.

Pictures are as follows:

2. Pin used to "burn" through the plywood to ease the servo screw access
3. Pin is heated
4. Holes made using the pin
5. Servo now mounted
6. Control horn for elevator
7. Partly screwed in
8. Screwed flush with the top of the elevator
