Just an update to the roll trim connection to the Ray Allen servo.

The issue has been the connection to the CF spring. Here you can see my latest solution which I am very happy with.

Sure, its a minor thing. Normally the spring connection is rotated to match the other end, which I did originally. This works if your servo is also at 90 degrees to the spar. That seems misguided to me, why take up more room next to the firewall where access is always an issue?

The solution was to thicken the right hand side end of the spring with many extra layers of Carbon fiber (CF). Then I carefully cut a slot to receive the servo tab.  Next was a slightly longer clevis pin and I now have a system that makes sense to me.

You can just see the spring in this recent shot of the build.
