Nashwan,

Leave off. This is a thread about the Fw190's roll rate. There are other times and places to discuss the concerns you express.

Hristo and Jekyll,

Why are you charts showing such different results for the Fw190 in AH? Hristo's shows a small discrepency, except at high speed, and Jekyll's shows a large discrepency.

Hristo's:

Jekyll's:

Which is correct and why are they different?

My mistake Hristo, did not realise what was being implied by Nashwan.

All I know about Jekyll's chart is that it was made few versions ago. When I saw the discrepancy, I redid the tests and came up with same results again.

It was my mistake not to take the tests in the first place, this whole thread would have different headline

. Sorry.

Anyway, and in short: 190 is right on, except at very low speeds (too slow in AH) and high speeds (too fast in AH).

Other planes show even greater inaccuracies, with P47 and Spitfire leading the pack. They all roll too fast.

Hristo,

Next question, how do we know that the other's roll too fast?

All we know is that they roll too fast if AH limits the stick force to 50lbs. The same is true of the Fw190 at high speed. Maybe 50lbs doesn't deflect the aerilons as much as the amount of force modeled in AH.

If AH is modeling 75lbs of stick force then the aerilons would achieve higher deflection and thus the roll rate would be higher, up to the limits of the airframe. The Fw190's lightness on the stick might mean that 50lbs is able to achieve full aerilon deflection at some speeds, but then it declines faster than 75lbs of stick force.

See what I am getting at?

Yes, I see what you mean, as long as you model same pilot for all planes though.

Karnak · « **Reply #65 on:** July 20, 2001, 01:32:00 AM »

I agree.

The only way we will ever know if it is being modeled the same for every plane is if HTC tells us how they are modeling it and with what criteria.

I, quite frankly, don't know anywhere enough about it to do anything more than posit, hopefully intelligent, questions.
