Whatever happened to the prop pitch on the Dora? It seems like sometime around when AEP came out the prop pitch changed dramatically. I can run the dora around at 100% prop pitch my whole flight now and the motor will not overheat and die... It came in very usefull for me when diving away from another person or trying to gain altitude quicker. Does anyone know what happened???

100% "prop pitch" just means full rpm. Is there any reason it shouldn't be able to? How does this compare to what you observed before? You are apparantly saying that you aren't using it on auto. I don't recall with the Dora, but for the A-series on "manual" rpm behaves more like a CSP control. What does the rpm do when you are running it at that setting, compared to what it does when you run it on auto?

The Dora now uses a constant speed prop (in manual mode) like other aircraft, such as the P47 or La5FN. Originally it used the system like the Bf109, but that was (imho) incorrect, it now has its historic control system, namely the Kommandergerat (auto mode) with constant speed prop (manual mode).

Michapma, there is a slight increase in RPM (100-300?) when running in 'manual mode', which is probably incorrect. However that is the way it is currently (and previously) modeled, for both A and D series 190's. However, imho it is a very minor performance gain (maybe 5kph, 2m/s?) for a siginificant increase in heating, not worth it for me at least.

Yes that must be it then what I was trying to say before is that when I had it on manual control the rpms acted the same as the 109s. Well I guess if its historically accurate then I am for it. Thanks for the reply.

Even in 1.22 you could run the Dora or any 190 at full manual prop pitch w/o having to burn the motor like a 109. Nothing has changed except the radiator settings. Auto/closed I believe no longer opens and you must manually change the rads to cool her down quicker which is now historically correct. Someone please correct me if I'm wrong here.

Did anyone see that or was it just me?
