Has anyone installed an autopilot in a completed -4? If so, what brand did you install and where did you mount the servos?

Thanks,
David

Yes.....

.....we're going through that now with my buddy's -4. The aileron servo mounts under the floorboard, on the right side. A hole allows the pushrod to go through the fore-aft web and connects to a clamped-on arm on the torque tube. The elevator servo mounts behind the elevator horn, under the baggage shelf.

Tru-trak has a PDF file at their web site that shows the installs on the different airplanes.

I installed a three axis TruTrak in my RV-4 about 2 years after completion. It is hardly a monumental task. Installation is straightforward. Spring for altitude hold. You will never regret it. Adding an a/p to an RV is the best investment you can make and Tru Trak's customer service is impeccable.

Pierre, Doug,

Thanks for the feedback!! That was just what I was hoping for. I?ve been looking at the TruTrak ADI Pilot II but was concerned about how difficult the servo install was going to be. Given this information I think this is the route I?m going to take.

My RV4 Trutrak installation

These pictures might help. Its easy though the space is tight for the role servo. Scroll down to 11/8/07 and 10/14/07.

Good luck.

I didn't want to drill out and reinstall the rivets for the elevator pivot bracket in the cramped confines of my RV-4's baggage compartment. I modified the bracket from TruTrak and piggybacked it onto the old bracket. Much easier, IMHO.
