It says:



The essential part, marked as bold font translated: The RPM is increased by pressing the Lever upwards and it's decreased by pressing it downwards. The Lever returns to the neutral position by itself.

That basically means it should be controlled just like the trim or the water radiators. So the way we have it now is not correct.

+1 for realism!i only fly the bf now and if it worked the way we have it now in game,then please keep it.btw, now i think you can control it much more accurate than before.
and i dont see the problem...why is it not correct the way we have the pp now?

i think its exactly the way it works now.

This very interesting topic, who wrote the original post (schwarze-man), it is possible to contact him somewhere? I did not find it in my documents from the velocity of the propeller pitch accurate information.

But, if this true:
"The prop will adjust its pitch at a speed of 1.5° (degrees) per second for as long as the rocker switch is held and then stop when the switch is released. The movement of the pitch indicator is clockwise=fine,anti-clockwise=coarse. 1 Hour=6°,10min=1° so,1.5°/sec is 15min/sec or 1hour in 4sec! The range of the propellor is from 12.30 (full fine) to 08.30 (full coarse) and this equates to a pitch range of 22° to 46° "

...It is necessary to fix this in the game then! In COD (1.01.14588 patch), PP moving from 08:30 to 12:00 (21°) takes 58 sec! This means it, that PP moving speed 0.36°/sec. Compared with the value written early (1.5°/sec, or even in other documents 1°/sec), this huge difference, huge disadvantage (totally irrelevant, that PP are automatic or manual)! Some authentic source would be very good from this.

Schwarze-man has been responsible for a number of DB605 engine restorations he is about as "experten" on DB engines as you are going to get !

a speed of 3° per second is giving for a VDM propeller.
So, as one hour on the gauge is showing a difference of 6° of propellerpitch change , with the actuel speed of ~16sec for one hour , CoD is to slow indeed.

CoD = 6° in 16sec
real (according to linked book)= 6° in 2 sec

Which VDM propeller and in which aircraft ? Fw190 kommandgerate operation has a different pitch slew rate to the DB system that lacks kommandgerate.

I did not know him, but im spoken with Kürfürst an afternoon, he said who he is. He tries to establish the contact with him (there were a couple of exchanges of e-mails with years before). But - according to these - he totally reliable source, there is not a claim onto an other document. Right?

i dont know. And wondering why the electric system of a VDM should work in different speeds with a BMW or DB601.

Anyway, if you choose 1° , 3° or something between per second, all is better than this 0,3...°

I communicate regularly with Schwarze man. As I indicated before he is a true DB605 expert. What he says is Gospel.

Because the FW190 system was a far more spophisticated system than that used in the BF109. There was no Kommandgerate system on the 109. I am away from some BMW801 refrences at the moment. In those refrences are some BMW801 Prop pitch slew rates. Once I find them I will post.

The speed of propeller angle change is a function of the speed/torque of the electric motor that drives it, not wheter the constant speed govenor system wassophisticated or not..

Currently, from what I've seen in the forums I see the the following problems with Bf 109E propeller pitch control:

1, As per Luthier's newest patch log, the 109E-3 changed propeller cannot be feathered.. silly. The December 1939 109E pilot manual instructs the pilot to use "Segelstellung", ie. "Sailing Position" = feathered propeller position. The 109E could be fully feathered!!

2, The instument board pp. change lever has labels and positions for groBer and kleiner Drehzahl (increase/decrease rpm) settings but the real one had an extra bottom position: Segelstellung. This was fixed, ie. the lever stayed there and keep the propeller in feathered position when set, explicetely for the purpose of freeing him from the burden of having the keep pressing the lever all the time1!

3, Appearantly something also went wrong with the propellor pitch change speed and it is now 0.3 deg/sec.. bah. The documented figure is about 1 deg/sec.


In short what needs to be fixed:

1, (re-)Adding a fully featherable propellor and key binding for it on the 109E series, plus graphical rework of the dashboard prop pitch lever.
2, Fixing the propellor pitch speed change which became abnormally low.

Hali. Már én is beraktam ide korábban erről infót, hogy három helyett négy állású lenne a légcsavar állásszög állító kapcsoló, de nem igazán foglalkoztak vele (és a középállás is szar helyen van emiatt jelenleg):

Nem baj, minél többször látják, talán valakinek eszébe jut kicserélni.

[Absolut]

realistic or non realistic...blablabla , is its realistic that my reargunner can only shot when not moving, is it realistic that we all fly with no antropomorph, is it realistic that i alwaysm lost sound , is it realistic that the bombs now droping like darts, is it realistic that i can bail out under a second in any position, is it realistic...blablabla.
i payed 69euros, and i play a well made accurate game that impressed with its option to set.(now a lot of them works well)
But i do not accept that some tolds thats realistic and dont talk about put any option for it, after i played it for a long time now.
OK, im seriously playing since the begining of il2, i never had to be posting like this, but someone brutaly handed with my messerschmitt 109, its no virgin any more.
Gentleman is that the way u give us performance?




no more propitch on this controls, is that ok?
im not amused any more, to spend time to fly my 109, its urs.
