I recently uploaded a walkaround video on my plane and it shows my set up (the video was not done for this thread). Although mine is a center stick I was well aware during the build of the need to set up the cockpit (flight deck) so as to prevent any "hand dancing" of controls at critical times. My biggest reach is for the radio which can be done with my free hand but is generally done by switching hands. I even set up the iFly GPS to be reachable with my free hand.
Admittedly mine is not set up for training but I've had instructors that felt comfortable giving me flight reviews with this set up and a few of my passengers like to fly it when I ask them if they would like to.
