Within the Aircraft.cfg and/or Air File, is there a way to modify/replace a fixed pitch prop with a constant speed prop? If so, what text needs to be modified?I fear that this may be part of the aircraft model and cannot be modified, but if it can, I sure would appreciate a little information on how to make this modification.Thanks:RTH

Interesting question, indeed. Which model do you have in mind?

In the aircraft.cfg under [propeller] The property "propeller_type" controls what type of propeller is used. [propeller]propeller_type=0 // 0=constant speed, 1=fixed pitch

Thanks Rahgen!So simple I overlooked it.Changing "propeller_Type=1" to "propeller_Type=0" did the trick.CoolP, I was thinking of the Junkers_J52.Happy flying:RTH
