After 10 hrs. flying with Garmin autopilot GSA28 servos with a G3X system, I've got a few questions.
With the roll servo set to .25 torque and a gain of .35, it tracks a course adequately, but wanders a bit left to right, never more than 1/2 a dot off. In other words, it's a little lazy for my taste, so I increased the gain to .40 and then to .45. At the .45 gain setting, it wanders a little less, but when I hit some light to moderate turbulence the stick whipped left to right several times in rapid succession. I stopped it by just holding the stick, effectively overpowering the servo. Is there a happy medium between .35 and .45 gain setting where I won't get the whipping left to right of the stick in turbulence? My experience with brand TT in turbulenece didn't have the same effect.
In trying to get the autopilot to track a course, after selecting the HDG/NAV button, then the CRS button, the heading would keeping flashing and I couldn't figure out how to stop the flashing without pushing in on the joystick, which would cancel the course select and put me in heading mode. How do I get the flashing heading to extinguish and stay in nav mode?
The vertical mode works very well holding altitude and climbing or desending as directed with the factory settings. The altitude is never off by any more than 10 feet.
Thanks in advance for your responses,
Mike
