If all days in the "factory" could seem as satisfying as today I'd build 20 airplanes. Today was a marathon session that seemed to fly by with quite a bit to show for it in the end.
The picture below shows where the trim servo will be mounted. Although the motor/mount skid is removable, the servo itself is pop riveted to the mounts. I don't like the idea of have such a permanent mount so I'll probably end up adding some sort of removeble mounting system.
