I'm bumping this thread because I have the same question. I plan to use a Dynon system in my Series 5, and I'd like to buy the right servos the first time.

Can anyone with a working Dynon installation offer guidance on which servos work well for roll and pitch? As Henry mentioned above, there seems to be some lore that the SV32 slips in the pitch application, but I haven't found anyone saying the SV42 doesn't slip. The Dynon servo application guide suggests using the SV32 for both roll and pitch, but the table says this suggestion is not "known to work."

For anyone with a Garmin autopilot setup, can you please post the torque settings you use for roll and pitch? [For those unfamiliar, the Garmin GSA 28 servo is software adjustable up to 60 in/lbs. I asked the factory what settings they use, but they declined to answer.]

Thanks.
