Hello all,
I have recently installed roll and pitch servos in my FD180 (with latest S/W) equiped Sonex. Pitch (SV32 servo) set-up has been pretty easy although I haven't really tested it under varying conditions. But today it was holding the altitude within 10-20' in level flight. It did lose about 50' during a 180 degree turn so it may still need a bit of tuning.
However roll control seems to be more of a challenge. I have tried the full range of sensitivity settings and something in the 12-16 range seems to be the "best" so far, controlling within 3-4 degrees of set point in calm air. While this may sound quite good, the plane noticeably rolls back and forth to achieve this, which of course I would like to substantially reduce. After 30 minutes I was starting to feel slightly noxious so if I had a passenger ... well staying on auto pilot for roll control may have been cut short. No idea why, but roll control only has the sensitivity adjustment, while pitch control has sensitivity plus several other secondary adjustment options if needed (only one of which I have tampered with so far).
Any suggestions to help stabilize the roll servo from the group and Dynon staff??
Thx
Garth
