You're absolutely right funked .. the 190 SHOULD be toned down above about 300 mph. If you recall my very first post on the subject .. way back when I first did the testing ... I mentioned there that the 190 rolled too fast at high speed.
Funny how people never remember comments like those, ain't it
Out of interest, how does the Typhoon roll now with the newest FM? Has anyone compared its new rollrate with the NACA curve on the above chart?
Oh, and F4UDOA, you're right about the testing method. I think the most boring 3 or 4 nights I ever spent in AH were offline testing of the aircraft rollrates. By a very strange coincidence, the testing method I came up with exactly mirrored what the NACA engineers did (well, with the exception of the 50lb stick force limit)
5 individual rolls to the left, 5 individual rolls to the right. Each timed with a stopwatch from level trimmed flight.
Timing a single roll simply won't give you accurate results. No matter HOW hard you try, you'll always click that stopwatch either just before or just after you throw the stick over. Doing multiple individual rolls tends to even out these deficiencies.
One other thing to watch for is maintaining an absolutely level attitude during the roll testing. I must have done about 400 rolls which I couldn't include in the test results, mainly because I let the nose drop low during the roll. As soon as the nose goes low, airspeed increases (which generally tends to speed up the roll), plus when you try to maintain attitude by applying up elevator you tend to snap the aircraft around, resulting in a much quicker roll rate than that available by using aileron alone.
