I hadn't seen this thread in a long time. I have one of the few wireless autopilots sent to BETA testers a few months ago and it's impressive. It's the same as the one in the video above but since it's wireless, you only have to install the servos on the aileron, elevator, and rudder, then they connect wireless to the main box installed behind your dash. Each servo has their own battery and miniature turbine fan that powers and charges the battery in flight. Genius !!
I sadly had back surgery the week I received the autopilot so I couldn't install it on my Wilga, and since I'm now selling the Wilga to concentrate on flying the T34a, the new owner will have to install it (in less than a day) and enjoy it.
