German Prop Pitch Lever

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.
