The only thing that seems to work is to adjust the prop pitch (and everything else) manually? Any other advice on engine management is welcome (and neeeded!) http://ubbxforums.ubi.com/images/smiley/blink.gif

For most planes in the game, 100% manual pitch gives the expected performance of the plane. Many people drop pitch to 0% for landings because it tend to act like a brake of sorts and helps slow down your plane. With these planes you can't switch to auto anyway, so staying at 100% lets you fly without having to tinker with it. Some people feel that dropping the pitch to 75-85% gives a slight boost in speed for level flight IIRC.

For 109's and 190's, auto prop pitch tends to prevent the engine from overreving and suffering damage - but with a corresponding drop in RPM and therefore the plane falls short of it's maximum performance.

Most models of the 109 require extreme care in manual pitch and most cannot take 100% without destroying the engine...I tend to leave those on auto and just fly, especially the later series MW50 equipped versions.


For the 190 A series and the F, 100% manual gives about 250 more RPM and can be pretty much left on without risk of damaging the engine...climbing or diving has little chance of overreving. The engine overheats faster but the risk of damage is low, so with proper radiator use to keep the engine cool those FW's fly with a little bit better performance than on auto.

The D9 series gets the biggest boost on manual of the series in my opinion. At 100% manual, RPM is about 3500 or about 400 more RPM than on auto. The difference is quite noticeable especially in climbing. The engine overheats rapidly, so this is a constant on/off thing. Some care must be taken during the dive to avoid damaging the engine, but as long as the dive is shallow there is little risk. Steep dives for long duration tend to overheat the engine more rapidly and there is a higher risk of burning the motor out.

With the MW50 equipped 45 version of the Dora and the 109's, engaging the MW50 while the engine throttle is at 100% or over will burn the engine up in no time flat, especially on the 109's. The best practice for MW50 equipped planes is to engage it when the engine starts and then leave it alone. Everytime the throttle goes over 100% the MW50 kicks in for the boost, and everytime the throttle goes lower than 100% it turns off automatically. The MW50 engaged will continue to flash whether the mix is actually boosting or not and will stay lit even if the MW50 runs out and is no longer being injected into the engine...a general rule is 40 minutes total time of use with no more than 10 minutes continous engagement, though I don't really know if this is modelled in the game as it was in real life.

This is different from the Erhohte Notleistung equipped Dora's and Antons. For those, you can turn the Erhohte on and off at will regardless of throttle setting. At over 100% it kicks in the boost, at less than 100% it doesn't. You could turn it on and leave it on if you like, I don't particularly see any reason not too from experience, though I don't personally. It's on/off for me depending on throttle.

The same default W key works for all German fighters equipped with a boosting system.



As far as prop pitch goes, for most planes leave it alone, for 109's leave it on auto, for Antons and the F series of 190's go to 100% manual and for the Dora use 100% manual for climbs or screaming level accelerations and use auto for diving.

In other words, don't expect it to behave just like the real plane. (i.e. mw50 at 101% throttle should lower the temp.) http://ubbxforums.ubi.com/images/smiley/16x16_smiley-sad.gif

TOcarrol, if you're serious about learning the finer points of engine management you can't go wrong on the link michapma posted. You'll also find some excellent training tracks by JG14 Josf which I am studying myself very carefully. Also, here's a quick but very useful study that will get you going that was posted by Pye awhile back:
