I also changed the bellcrank geometry since I had it out and on the bench. I took 1/2 inch off the output arm to help the leverage a little.

Sorry this took a few days for us to notice. We don't stick our noses in the autopilot section as often as we should.

We do have some reports of trim indications not being as accurate as they should. Unfortunately, this isn't user adjustable. However, the good news is that we have been testing an updated trim detection algorithm, which seems to work very well, and should fix this issue with a simple software update. We expect to have this update in the next software version.

So for now, if you are having the issue, all we can tell you is to ignore the alerts for now. It's not indicative of any broken hardware.

...thanks, we thought it was our fault.

Thanks Dynon. As always you are on top of it. I look forward to the update.

Mike,

Thanks for bring this issue up, as you know I am having the same issues. I look forward to Dynon's software update!!

Dynon update
 
Will the update be for the 100 series as well as skyview?

The release we are working on currently is for SkyView only, in order to see if it is an effective improvement. If it works, we will discuss upgrading D10/D100 products.

10.2 Beta now out
 
For those of you with a SkyView and are getting inappropriate NOSE UP or NOSE DOWN indications, we have a public beta to test a fix for this.

Got it. I'll fly it some this weekend.

Thank you!

I flew a two hour round trip yesterday using the new AP program. Testing the results I found the pitch in perfect trim each time I disengaged the AP.

But it seems now that the altitude struggles to hold steady. I was cruising high in smooth air but several times a small bump would cause the pitch to hunt, up and down about 5 cycles 50 feet or so before settling. Also when I dialed in an altitude change either up or down it would overshoot the 500FPM then overshoot the new altitude starting the hunt again. Before this new program the pitch was rock steady.

Do you recommend any setting changes, or other thoughts?
