German Prop Pitch Lever

[Blackdog_kt]

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).

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.

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.

That may be true, but I'd almost go as far to bet that this was an analog switch that worked on resistance: the further you moved the switch away from center, the faster the prop adjusted up to the max, which was around .7 degrees per Kurfurt's note. This was simple enough back then, as there's no special pressure sensing, it would just be an increase and decrease in electrical resistance.


Edit: Changed the prop change speed after reading Kurfurst's post better.

Keep well in mind that the French report above is based on an assumption:

"assuming that the speed of the rotation of the electric motor to be 2500 rpm..."

then, IF this is TRUE

"the speed of change of the pitch would be of the order of 0,7 degrees per second"

Keywords: "assuming" "would be" "of the order of".

I presume the assumption by the French simply follows the gear ratios found, ie. IF the e-motor runs at 2500, THEN the prop pitch change will be 0.7 degrees/sec."

HOWEVER the speed of the rotation of the electric motor (VDM Elektrischer Drehzahlregler 9-9518B type) appears to be 5700 /min, and NOT 2500 /min as the French assumed. Ie. a bit more than TWICE as fast.

See: D.Luft. T 3810 VDM Verstellscharuben Geraete Handbuch, page 19, page 29:




Based on the above, assuming about 1,5 degrees/sec for the 109E seems entirely reasonable. After all, that's about what every single source tells us, including Schwarze Mann. And it was so before in the patch..

A little more from Schwarze-mann



So in Static conditions 1.5 deg sec and in normal (under load) conditions 1 deg per sec. so in flight imo we should be seeing 1 deg sec pitch rate. This is consistent with all the references shown in this thread.

Devs are aware of this issue expect a fix soon.

Great. Thank you.
I was thinking about something meanwhile. It reports it if the velocity of the elektromotor changes (Kurfurst doc: PP motor 2000-6000 rpm), that with the switch can be made change in? slow or fast moving it depends, how much I drive the switch out from middle?

[edit] No. I found the circuit diagram [1] [2], its only a simple switch. PP have constant speed.
Ok ok, i'm finished
