Ch 17 Roll/Pitch Trim System
Roll Trim and Aileron Servo Mount 2

Roll Trim and Aileron Servo Mount 2

Manual Reference:  no ref

I wanted to complete roll trims and aileron servo mount so I could put the engine mount back and keep moving.

The aileron autopilot servo filled well in its new position. I am happy with the double P-clamp idea and made a very simple triangle in aluminium with three holes to mount these and the end rod.

For attaching the spring to the little servo an AN42B-12 (drilled) worked out well. I did have to get the AN3 size hole filled in with weld and re-drill it for a small clevis pin.

Here are the two roll/aileron fittings in place.

I like this shot with the lower cowl on. Looks ‘interesting’.

I had the small aluminium servo push rod center drilled for me on a lathe. I finished off with the 3/16″ tap. You might notice on the right of the servo holder is a piece of aluminium tubing. I was concerned that it was possible for the rudder cable disconnect piece to snag on the holder. The tubing allows any contact to just roll off. I cut a slit in the tube and secured it with one rivet. Simple.

The servo with its special pin in place. I’ll use a castle nut and split pin for the final set up. Lets call these good for now.
