Offline been testing out the Model 22. Noticed something really odd... With and without combat trim, you can roll pretty well either way until you pull up in a sudden burst. Maybe it's a cross control problem or maybe it's some funky G-meter spike bug, but the end result is you are unable to roll ailerons for about 2 seconds after you do this. It feels like you're doing 500mph and are locked up due to compression. However my tests were below 150mph.
I tested it getting up a bit of speed as well, 250 or so and got the same thing. Haul back on the stick just a tad, not even enough to change direction, then let go and you can't roll either way. Looking left at my aileron it wasn't deflecting at all. Then as it came back the aileron slowly moved into the upward deflected range. Then like a scaling curve rapidly returned to normal.
Repeatable every time.
EDIT: For clarification, I wasn't blacking out, I wasn't stressing, no creaking sounds or fuselage moans. Note, however, it did look like the G-meter was spiking pretty high (about 7Gs) for almost no movement or inputs. Tests done at 50% fuel.
