To all RV-9 builders planning on installing a Trutrak autopilot.... and a few flyers I suppose as well. The installation of the roll servo is different for the RV-9's than the RV-7's. The drawings that I was suplied with were for the RV7/10 and I didn't know any different. I had a few leftover parts. While looking at pictures of servo installs to see how the washers are supposed to be used, I saw the correct installation for RV-9's... and also found the RV-9 installation drawings on the TT website. Don't make the same mistake I did.
