FM's the State of Play with empasis on Climb performance.

I disagree.
We've been at it from day one about the FM's, and to the dev's credit they have been changed, they just need some more poking to get it right I think.
The squeaky wheel gets the grease after all.
Correct the 109's, and give us some real opponents to shoot down. If I wanted to shoot down ham-strung fighters with third rate performance and terrible pilots Id just wait till BoM comes around to slaughter the VVS.

I agree with IvanK, the RAF fighters perform well below the specs, the 109 is still not what it should be. I don't know what has been done in this version, but it's certainly not right yet. Thanks for the graphs mate!

CWMV - that was just rude about Russian pilots.

What i think that all these planes need a fair and deep Flight Model and expecially Performacne revision.

There are plent errors in maxium speed, climb rate, RPMs settings ( power settings) for Merlin engine, slats working, stability and controls ( expecially rudder) working.

I wonder why 1C reduced speed of british fighters if before it was more close to RL data and now it is way off even for 6 1/4 lbs power.

It was need mostly to correct 109 speed range.

I wonder if they will manage to do it in accurate way ever?

I dont even want to think what they will get in Battle of Moscow with russian planes if they have problem to get correct FM&performacne for a few BoB planes?

IMHO another thing that needs to be looked into is best climb speed. AFAIK the best speed for climb for the 109E in the sim is 270-280 kph IAS. This would be correct for the 109G, but the E's best climb rate was at 250 kph IAS.

This might sound as a small thing, but it seriously effect the climb curve. The FM calculates climb via a generic formula, where Vi=best climb is the peak and Vi= max level speed is 0. Shifting Vi=best climb to higher speed will thus reduce low speed (steep) climb performance and too low Vi= max level speed will reduce high speed climb, zoom etc.

This can and does effect tactics such as climbing turns, using different climb angles etc.

A bit of a clarification, I wasn't suggesting you made your tests badly, dear Ivan! However from what I remember from the SFS files is that the best climb speed of the 109E in the sim is defined as 270 kph instead of 250.

Did you write down the climb speeds you used as well?

Kurfurst is correct. All aircraft performance occurs at a specific velocity and it fixed by the design.

If the relationships of lift and drag are correct in the model, it will reflect in the best rate of climb speed.

Those airspeeds are listed in the appropriate Operating Handbook for the type.

I would also suggest conducting saw tooth climb schedules to determine the Vy and Vx of the models in the game.
