G'Day All,Can anyone tell me how to modify the aircraft engine files so that when the carb heater is turned on the engine RPM falls and conversely when it is turned off the RPM increases?Cheers,:-hmmm

G'day Ian, I'm pretty sure that it can't be done by simply modifying anything within any of the Fly!! files. I'm not a programmer but I think it will require a purposely written script or DLL.It might be possible to achieve what you want with Fly!scripts using Python. Failing that it a job for C++.I'll let one of the programmers give you the definitive answer though as the above is purely a gut feeling.Any guru's out there able to add to this topic?Bump - ....Cheers,Roger
