I know, I’m aware of how a snap-roll is performed - however, most users won’t be and will simply throw the stick in the intended direction and expect to see a result. They won’t know about wing-stall and rudder. I have to be mindful ( or I feel that I do ) of these things when creating aircraft and remember the end-user may not have the same knowledge of aviation as a pilot like yourself ( or me, PPL ).
I have the same problem in reverse also - I routinely get e-mails complaining that the F-15s won’t do Mach 2. “I’m at full afterburner, 50,000ft, and I’m only seeing 550 knots! This is garbage!” etc. As a pilot, you’ll know why they’re already at Mach 2.
A product like the Stearman is designed to be representative of the aircraft, but won’t I don’t think ever reach absolute accuracy. Enough folks have mentioned the roll-rate now though that I think we’ll make the change, along with the increased drag - I always say that if enough folks want something then I’ll do it, and it seems to be the case here
