Am I doing something wrong? I have an AMD 64 Athlon X2 system with 4 Gb of RAM. FSX default Beech Baron BE58 gives up to 40 FPS and the Aerosoft B747-400X between 25 and 40 FPS. However, my PA31T Cheyenne II XL from Aerosoft only gives up tp 20 FPS and drops to 5 FPS at times. When switching from 2D panel to 3D panel I get a 'grey out' and a delay of up to 5 seconds before the frame is restored. Have I not set something correctly? Any help appreciated.

Have the Piper Cheyenne PA31T and have changed the registration letters to my personal registration. However it only shows on the instrument panel. How do I change the external registration letters to match? I seem to remember it involves going into a text file for the model I am using and just altering the letters where they appear - does anyone have the full answer?

Thanks gentlemen for the replies. As you have said - I have now been able to program the power levers and prop pitch levers. I'll just have to get used to using the 'mouse' to switch from High Idle to Low Idle etc.

I have just bought the Piper Cheyenne PA31T turbo-prop. Can anyone explain how to program the Saitek throttle quadrants to give me reverse on the power levers, prop pitch feather on the pitch levers and also how to program 'High Idle', 'Low Idle' and 'Stop' on the fuel condition levers. I have the fully registered version of FSUIPC. I was expecting the appropriate detentes to come up on the FSUIPC calibration page - as the flap detentes did for my PMDG/Aerosoft B747-400, but I don't seem to have them. Am I missing something simple? Any help appreciated.
