Trio servo placement

We are ready to install the servo for a Trio Autopilot and wondered if there are any others who have gone before us with suggestions or tips on location (between seat ribs or wing tips etc), and mountings. We are leaning toward placing the servo between the seat ribs however it is a tight fit to say the least, not leaving much room for adjustments. Any feedback would be greatly appreciated.

I opted for wingtip and used SafeAir's servo kit (www.safeair1.com) to save a bunch of time - it was super-quick to install; about 2 hours from nothing to done and I didn't have to spend hours speccing and ordering pieces-parts.

I initially wanted to mount the servo near CG on my 8A, but it was getting 'way too complex for what was probably gonna be negligible benefit.

I used the safeair wingtip installation. Very straight forward and easy to install. Works great. Jack
