I was cruising through RV10 stuff and stumbled upon this youtube video. It's got a -10 with turbo, air conditioning, and ifr...but what grabbed my attention was the side stick controller (like the Cirrus) installed. Shows up about 2:10 and again at 2:40 in the video.
The engineer in me would say..."don't mess with the control linkages" since the linkage system in the Cirrus is way more complex than the Van's. And yet...
Text with the video is Portuguese; I'm barely conversant in English.
