I have an M20R and have had both trim servos "repaired" by STEC in 2 yrs. (one of them for the second time last week). Yoke mount trim doesn't work at all but appears to be operating in autopilot (so long as its making only minor adjustments). This is a frustrating problem and now an expensive one (last week's "repair" invoice from STEC was $990). Any advice appreciated...
