I pulled up the seat pan and tweaked the pilot’s roll push rod by 1 full turn to straighten up the stick. Later flight test showed that to work very well.
Looked at the pitch servo while I was under there and confirmed that there was good power to the servo with the appropriate switches on the panel. Damn. That was the easy fix I had been looking for. I pulled the servo and took a closer look, not really knowing what to look for. Upon closer inspection, I realized that I had had a major brain malfunction when I did the wiring for the plug to the servo. Only the ground and power were in the proper position. I’m amazed that I didn’t kill anything. I pulled the wires, ordered replacement sockets and installed them a few days later. On power up, I had the Dynon go through the system discovery routine and this time the pitch servo was recognized!
I turned off the autopilot and will not try it again until I pull the back panel and check out the pitch servo. Since I wired them both on the same day, I’m pretty sure I messed that one up, too.
There were some problems installing the updated system software. I couldn’t get the Dynon to recognize the package from Van’s. Dynon tech support suggested a freshly reformatted memory stick and their distribution instead of Van’s distribution. Uploaded just fine, so I’m now flying behind system 14.2.1.
My previous observations with bizarre winds aloft and inaccurate synthetic vision have a poorly calibrated magnetic heading as a common input. I elected to not debug that any further until the system upgrade was done. Having accomplished the upgrade, I did one more ground compass calibration and then an air confirmation calibration. The installation manual wants to see a “quality” figure of at least 70, my unit reported Quality 120. After that, winds aloft and synthetic vision are now much more believable and accurate, respectively.
On June 30 (date of this post) I did 4 touch & goes at Marion (runways 31, 25, 13, 07. Great fun!) High approach DLZ 28 and overhead break with 360 to landing. Getting better at anticipating float and touching down nearer to desired spot.
