I know we are all friends here. I've got about 100 hours in the SR22 in the last year so I've got a somewhat decent feel for the aircraft. The only thing I am pointing out is that the autopilot will not hold altitude when deploying / retracting flaps. That unequivocally does not happen in the real aircraft.
I was experimenting and even if you increase yoke pressure forward (while on AP) to prevent plane from ballooning for ~5-7 seconds, the plane will still balloon the second you release pressure. If you at the same time manually adjust the trim, it seems to alleviate the issue.
Hence, my not so very scientific conclusion that the underlying issue may be how the AP interacts with the trim. I know the early B58 Laminar G1000's had a similar issue and it was fixable by editing a few settings in the plane maker. For some reason I can't get that application to load anymore and apologies but lost my notes on what you had to adjust on the B58 to fix this issue!
The other thing I would highlight is just around the power settings. The NA plane often seems to need about ~10% more power than real life during instrument procedures / patterns. Per the Cirrus book (at least for G5/G6 NA I am not as familiar with G3), in level flight 37-40% power will get you about 120 knots and 30% power will get you around 100 knots. 40% power with 50% flaps gets you around 100 knots. May just be the G3 vs. G5/G6 airframe differences, but wasn't sure if perhaps there were other drag type settings that perhaps could be tweaked to get this as close to real life performance as possible. Look at page 3-61 as an example in the official cirrus flight operations manual - http://whycirrus.com/safety/23020-002_RA_Std_FOM.pdf
Last comment - the throttle in the NA also seems a little jumpy in mid level settings. It's just not smooth when fine tuning. Both using joystrick throttle and more precise keyboard shortcuts.
p.s. This is all in the spirit of making what is already awesome even better. I have been waiting for a proper Cirrus for years! Finally can have the Cirrus functionality as well as pop-up windows, switch control, etc. Great work. Always willing to help test out adjustments as well. Will soon be pairing this with the realsimgear equipment.
