Once you have it properly wired, check the trim calibration. Mine came programmed in reverse. The autopilot ran the trim backwards as evident by clutch slips and out of trim condition when I disengaged autopilot. I went in to the settings, re-calibrated the trim calibration and it worked beautifully.
