Ok. Here's what I did. I took a K4 and tried to take off with 70% power. I was unable to do that. It just wouldnt' accelerate enough. It weighs 3 360 kg and has 1475 hp, indicated.

I tried the same with La-7 and 50% power. I was able to take off _easily_. La-7 is slightly lighter, 3260 kg and has 1850 hp, but the info doesn't say is it the indicated power or the absolute maximum (Forsazh! or whatever)... For K4 does 1850 hp with boost.

Anyhow, it feels odd. Maybe we should all just fly La-7 then. I sure as hell will fly it more...

I have an idea, too. It would be nice if the "player x shoots down player y"-messages could be more like "player x's La-7 3xB-20 downs player y's BF-109E4"... It's not just the pilot, the machine, too. Go play counter-strike. Glock isn't as effective as an AK-47. /i/smilies/16x16_smiley-wink.gif

So there is red-bias in counter strike too then? /i/smilies/16x16_smiley-very-happy.gif

Lukki, I'm not surprised, it's like cars, everyone konws that Mercedes Benz/BMW has the worse engines than Volga or Zhiguli, those russian enginneers have been really marvellous, you know that?

I just came back.. it was another airfield but anyhow I was able to take off with 1941 LaGG-3 with 50% fuel (as always) and here's the amazing part... Only 51% power!!!!!!!!! And LaGG-3 (1941) weighs 3350 kg!!!!!!! And it only has 1050 hp!!!!!!!!!!!!!!!!!!!!!!!!!

I urge someone to fix thiiis.. pleeeeeeeease.... /i/smilies/16x16_smiley-sad.gif

Back again.. same airfield now. La5 1942 with 45% power and it took off easily. The tail just rises and it accelerates to 160 in no time. La5 weighs 3230 kg and has 1700 hp...

No, wait, I got my K4 in the air with 70% power.. it just took the whole runway to do it.. http://ubbxforums.ubi.com/infopop/emoticons/icon_biggrin.gif
Just can't do it with 50% power. The runway ends. How La5 and LaGG-3 (1941) do it is beyond me...

I was able to take off with the K4 at 70% power but it was not as easy as with a red plane.

But I took off and climbed to 5000+ meters with 70% power applied the whole time.

You may be right and the La's are overpowered.
But... I think you'll find that if you take off with manual pitch (trying not to exceed 2500 RPMs too much) you'll get a much easier takeoff. Seems the auto pitch is porked on some of the 109 models ATM.

Hey, thanks pal. I was able to do it by setting prop pitch to 100% and with only 50% throttle. Guess my incompetence makes it seem like it's unfair. Now who can explain why Russian planes can fly anywhere at any speed with prop pitch at 100% without breaking the engine? /i/smilies/16x16_smiley-very-happy.gif

RPMS and powerband are what matter. us take off flaps and use your pitch in k4

Take a FW-190 and try 50% throttle. It hardly accelerates. You'll need more than that for taxiing on the ground DOH. The La-7 can taxi with less than 20%...

It's not a power thing it's all about prop pitch.The german planes have a linked throttle if you set the power low then it also drops the pitch.Thats why you cant take off at 50-70% power.

Yes that's right. Did you have prop pitch at 100% in the Russian planes, Lukki?

70% in the 109 is like 70% power AND 70% prop pitch. I'm not sure what effect throttle has at the moment in FB - it doesn't seem to be huge - but with 100% rpm set it seems that 50% 'power' is still quite a bit of power.

Russian planes can fly around at 100% because that's what the engine is designed to run at - although not for extended periods. The prop in a 109 is governed differently, and setting manual 100% pitch at too high a speed can cause the engine to rev at well above its designed speed, thereby burning out quickly. That isn't the result of any bias.

Correct is Kernow and Pourshot.

70% in VVS planes mean 70% throttle + 100% RPM setting.

70% in LW planes mean 70% throttle + 70% RPM setting.

If any comparisons should be made, lower the VVS planes "Prop Pitch" to 70% also, and then try the same thing.

The K4 manifold pressure takes a real long time to build up.Manifold pressure equals horsepower and so this coukld be why a porked manifold model in the german planes is doing this.

Not quite - some one explained this a day or two ago. In the german planes, when you set manual prop pitch, you _really_ have manual prop pitch, so you can set it too high and over rev the engine. In the allied planes the "prop pitch" control is the % of RPM you want to run the engine at, and prop pitch is adjusted automatically to get this RPM. (there are some exceptions, but that's generally the case.)

This is also why you can't slow down so well in VVS aircraft just by dropping throttle - you need to drop prop pitch to lower the engine RPM.

Was it like that in reality?

Yes Lukki. Most Russian planes have CSPs (Constant Speed Propellers). What this means is that when you change the prop pitch in a Russian plane, you actually change the desired RPM, not the prop pitch itself. The prop pitch is changed automatically to attempt to maintain the set RPM.
In German planes, however, when you set manual prop pitch you are actually manually changing the prop pitch. If I'm not mistaken auto prop pitch in German planes should give you about the same results as the CSP in the Russian planes, but, like I said, it seems to be porked in many of the German planes.
