Comparing different feelings is moderately useful. Let’s try some meaningful measurement, assessing lateral stability. The sim is the same for all of us, but we have different sticks, different stick settings, sometimes different frame rate and different individual abilities. So, it should be interesting if everyone gives it a try, posting here the result.

I propose this simple test:

Starting point: a Bf 109 with wings level and carefully trimmed cruising speed.

Roll left to a bank of 5 degrees. Stop the roll and return the stick to neutral. Observe if the plane rolls back to level, noting how much time it takes.
Repeat to the right.

Roll left 5 degrees more, up to a bank of 10 degrees. Again stop the roll, return the stick to neutral and observe the result.
Repeat to the right.

Increasing the bank 5 degrees each time, we’ll hit an angle at which the 109 will stabilize in a steady banked attitude, having not enough stability to return the wings to level, but enough to maintain the turn.

Increasing the bank beyond that value, we’ll hit an angle at which the 109 will continue to roll, increasing the bank and gradually entering a downward spiral.

This test should be easy enough for everyone and, averaging different results, we’ll have some real, hard number to talk about.
