I had a similar problem yesterday in moderate turbulence. The plane fishtailed, wings level, and the EFIS showed rolls up to 30 degrees left and right. I have no nav connections to the EFIS. :(
I have a S-TEC System Fifty autopilot installed in my Lancair. The unit label says "This RFGC has been modified for use with King KCS 55A". Can I use this autopilot with my EFIS D10A?
Are modifications necessary?
