Since so much was said here about balance issues, I thought it might make the CG less of a problem since a single servo would be located not far behind the wing tube. It would also save weight. I don't own an Integral so I can't say for sure. As far as servos go , a robust JR (like the 8611A) might be enough.
Had pull-pull elevator on a Pursuit 120. It was a very nice setup with a great feel. A few will say pull-pull on the elevator is sensitive; but my experience was different.
