3 Axis Autopilot and Trim

[dmattmul]

Trying to gather some analytical data on the "ball" position in flight and thought it would be captured in the 118 parameters the G3X captures on the SD card. Can't seem to find it. Any help would be appreciated. I know rudder input dependent but feet off the pedal's comparisons would tell me something, I think.

Look for the "Lateral Acceleration" column. I've found that 1 ball-width displacement of the slip/skid ball equates to about 1/8 of a G.

Thanks Matt, should have known LatAc.

I had a chance to fly in a -10 recently on a bumpy day that had the yaw servo. There was a noticeable difference in the amount of tail wag with it on vs off.

The builder also did a demo by putting in full rudder, then releasing. Without the yaw damper the tail oscillated a few times before they diminished to center. With yaw on, the tail immediately returned to center with no bobble.

Worth $885? Probably.

To the best of my knowledge all of the autopilots that work with a -10 connect the pitch servos to the push-pull tubes just behind the battery. Access while sitting in the baggage compartment is pretty good. It’s better with the fully built tailcone pre-attachment to the fuselage, but not that much better. Things change in 5 years, I’d wait.
