German Prop Pitch Lever

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...°

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.

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.

And the Devs were made aware of precisely this a while ago ... so hopefully a further fix will ensue.

Mind you I cant think of too many occasions when you would want to feather a prop in a single engine aeroplane. Perhaps in the case of a failed engine and you are trying to minimise drag to increase your gliding range.

Just my two cents on our options and whether or not a feature was or was not included on any plane.

As far as our options are concerned, I'd love it for the prop pitch lever to function correctly, IMO and I may be wrong, this was push forward and RPM increased, move to middle, and it stops moving, pull it down and it decreases RPM, and again, move to middle it stops moving.

As long as we can functionally get there, and we are IMO, then the graphics can come later if at all. (personally i'd love to see that, but I'm not withholding my support from 1C over it)

Now, whether or not the Auto function with CSU fitted as a field mod came into service in Dec 39 or late 40 is a moot point. Even if it did see service in 39, this is not that plane.

From the looks of the switch, and I've seen a few as a mechanic, if it's springloaded in the middle position, then it doesn't have to be in the locked in the lower 'Segelstellung' position in order to feather it. The notch was just built in so that the pilot could quickly reach up in the event of an engine failure, place the switch there, and then the prop would feather as it's being held in the that position. You should still be able to feather the prop by holding the lever down, if you wanted to for whatever reason.

Good to hear that. Mind you, I am patient with Oleg and his team, I am just noting these issues so if hopefully the Devs read these boards, they have chance to fix it some time or another.

Agreed, its not a serious issue.. though I wonder why they removed it in the first place...?
I may be ignorant of the practical applications of feathering a propeller, but isn't that the only reason you'd want to feather the propeller on any plane...?

A bit of an info I managed to dig up (English transation of the French technical report of Bf 109 E-3 WNr 1304, captured in late 1939 in France, subsequently tested in Britain)

You're probably correct.
If you've seen a picture of the actual instrument there's a detent on the lower position to keep the switch there, probably so that the pilot doesn't have to manually hold it there and fight the spring-loaded return to center while it feathers.

On the other hand, it could also be that the detent enables an extended range of motion that's not available via the normal control range to prevent accidental feathering in flight.

In any case the operation is similar from the pilot's point of view, it should pretty much work the way Kurfurst pointed out: spring loaded 3-way switch with a separate feathering detent, corrected rate of pitch change (it's too slow currently) and if i may add, solving the reversal issue (controls are backwards now).

You can still use your controls for prop pitch. There's a big zone that corresponds to each switch position so it's pretty easy to do.

If you move your slider up or down it's like holding the button in that position and pitch will change as long as you hold it there, return it to center when you reach your desired pitch and it will stay there.

And yes, it's actually more realistic this way.

No offence, but i think a lot of people carry their IL2:1946 habits with them and that's why they can't get to grips with how many of the controls work. I had some trouble too initially, but now that i understood how most of them work i find the new way of doing things much better than what we had. Real planes don't all have the same controls and it's good that this is reflected in the sim. Sure, there are bugs but patches are frequent and we're getting there.
