Hi guys and gals, finally got my Pmag installed in place of my crapped out Right side Slick mag, all went well and back in the air.
now I want to try and get my Dynon 180 autopilot working right. When I try to track a heading it wallows back and force. I’m using a SV42 for the roll, no pitch yet.
i have the sensitivity on max (25) torque 100%
I tightened up my aileron cables as tight as possible, the shear screw is not broken.
seems to be a fair amount of play when the autopilot is on, on the ground , when I try to move the ailerons by hand.
if you have the same setup and have yours working well, what am I missing?
spoke to Dynon, told me to check the play in the ailerons and check the shear screw. Done both.
I am not familiar with the D180 since I have and HDX. What kind of connection do you have on the ailerons? A arm/link on the yoke OR a cabestan pulley with wire cables? Can you share a picture of the mechanical installation. Can you adjust the Gain on your AP like we can do on the HDX? On mine I raised the gain by 10% until good and its not chasing anymore.
Here is a picture of how mine is installed. (On a CH650B) I used the Arm/Link setup.
i ended up installing a extra doubler under the aircraft to stop the servo from flexing the sheetmetal, drilled a hole on lowest point of aileron horn, settings used in dynon install guide have worked out nicely for me, the power of the servo really flexes the skin without a stable mounting
Have you checked the accuracy of the Dynon mag compass? Maybe time to redo the alignment, latest Dynon software? Just some more ideas
I check next flight, been hand flying mostly. The nav and heading are great some wallowing on track mode. I trim aileron and elevator for hands off before engaging AP. Dynon recommended setting is bank angle rather than roll rate from what I recall
My setup is similar on my 601XL-B. D10-A, two axis Dynon AP, SV-32 servo to ailerons. In calm air it works pretty well however, if there is turbulence it seems to get confused and apply incorrect output to cause wandering. I have checked everything, re-calibrated the compass. Usually a constant 10 degree variance before attempting to correct. Occasionally
much more. It is similar in both track and heading mode. I have no solution yet so I am interested in the solution.
Sv-42 on roll , 32 on pitch lube the roll tube frequently for ease of movement
