I'm planning to install a Trio Autopilot in my PA28-140. Some C172 owners have installed it in Germany. The documentation for expectance by the EASA is available by a German. As I'll do it in Germany documentation and information support is essential for me. I need some first hand information regarding installation effort especially regarding pitch servo installation, support reaction from the STC group. Some pictures, sketches or similar would be helpful. I plan to do it with my shop who has already installed a C172 Trio application, but is in doubt regarding the effort for the pitch servo installation in a PA28-140.
