GSA 28 Servo Installation

I'm seriously considering the G3X as the platform for my RV-7A. I'm currently working on my left wing and was wondering if the GSA 28 roll servo gets installed in the wing or in the fuselage. If it's in the wing, wouldn't now be a good time to install it, while the wing is still open and I have easy access?

Thanks!

Garmin has stated that their servos will have mounting dimensions that are compatible with the industry standard (TruTrak). That being said, the TT servo mounts in the wing on an RV7A. Mine is in the right wing.

I have installed and removed both Dynon and Trutrak servos and brackets in a completed wing. No problem doing it later. The hardest part is the safety wire...
