see 5.

Note the comment by the pilot of the 109 saying the trim adjustment was heavy. In other words, it was not easy to rotate the wheel.

No wonder the 190 went to an electrical trim for the stab.

That was in a dive, where the 109's controls were all very heavy! That is not representative of how heavy the trim might be in a horizontal maneuver. Additionally, others have said the large wheel made it easier than competing designs, and I don't think we should be looking at the 109 trim in isolation.

What SHOULD be taken into accound in CLOD, and is not, however, is the reputed heaviness of the 109's controls in a dive. I've never had to use trim to pull out of a high speed dive in CLOD, and I feel that I should.

What is also interesting out of your linked notes is that the 109 lacked oxygen gear - would this result in a higher effective ceiling for the red fighters?

Extremely interesting also is the pilot's notes on the tendency of the Hurricane pilot to black out where the 109 pilot would not. Initially I read this as pulling more G's, but in actuality, they are saying that the pilots of a hurricane sat more vertically and had a tendency to black out even in similar g maneuvers! I definitely don't see blackout tendencies modelled in the sim, and that would make it rather interesting, wouldn't it, if the 109's pilots could sustain more g without blacking out!

We shouldn't pay attention to just one aspect of that pilot's report.
