Hi allMy XP install of FS9 has done something strange lately. I can no longer go to full throttle! Regardless of scenario or aircraft selected, the engine rpm maxes out around 2100! Engines also tend to stall at idle. I have re-calibrated my joystick with everything looking as it always has. I made sure sensitivity is on max and null is on min. Raw data during calibration shows throttle going from approx. 5 to 85. I have compared all references to throttle in the cfg file with saved cfg files from years ago and can't see any differences.Today, I disabled the joystick and just tried F4 on the keyboard with the same effect...2100 rpm max.If anyone has any suggestions, I sure would appreciate some input as I am out of ideas and don't want to start over with a complete FS9 re-install. thanks to all for readingWalt in Centennial, CO

If FS9 regenerates it

BjornThanks for the suggestion. Regenerating the cfg file did not fix the problem. I still have 2100rpm max using just the F4 key.regardsWalt

Hmmm, back to the drawing board.

Are you using FSUIPC? If so try calibrating your throttle in the joystick section.

Try it at a sea level airport?

Please mention the aircraft that gives you 2100. If it is a King Air, well, then the propeller is overspeeding since the max rpm are 2000. If you're talking about a piston engine and taking off at high elevations (3000ft and above), try to lean the mixture until RPM peaks.What do you mean by "Engines also tend to stall at idle"? I've never seen a stalling engine in FS, and since engines usually stall when accelerating, that makes it even more weird.

Agreed...What altitude are you testing at?

I'll throw in my two cents: try Alt-F4 and then F4. Joshua

Thanks for all of the input, still no luck here. I don't have FSUIPC and now I am using only the keyboard to troubleshoot this @#$%^& problem. At the latest test airport (TEB) the altitude was +13'. I was using the default MS Cessna 172 at Meigs and the Carenado Mooney at COS when the engines stalled. (rpm dropped to 0 = no running engine) (bad fuel?) HA! Googling the problem, I found someone way back in 2004 on Airliners.net with the exact same problem but he didn't find a fix.As for Alt-F4 then F4, my XP computer closes the active program when Alt-F4 is pressed.While writing this I went back to settings and enabled "Ignore Crashes & Damage" and "Auto mixture"... F4 gives 2100rpm (sigh).Microsoft...I'm still glad I met 'ya but I sure wish that FLY! could have stayed in business and thrived! Imagine the possibilities...Walt

Try to insert the CD-ROM and choose repair.

Walt,Sorry for my mistake (ALT-F4). You should try CTRL-F4. This is the default key for setting Prop RPM to High. I had this problem once and it occurred when I went from a small GA addon plane to the default C172. I set the props low on my stick and it somehow got stuck that way when I loaded the C172. Holger actually gave me the tip to try CTRL-F4 years ago and it worked for me. Here's hoping it works for you.Take care,Joshua

JoshuaBLESS YOU SIR!I don't have a clue as to why or how but Ctrl-F4 did something for sure. I tried it at TEB , APA and Meigs in the Arrow, the Mooney and the default Cessna and I AM BACK IN BUSINESS! I can once again reach redline! Thanks for all the help folks.I'll say it again, it may be all we have but at times MS Flight Simulator can sure get tedious.Thanks again.Walt in CO

All the Lockheed Constellation models stall if left idling too long. It mirrors quite well the difficulties of large piston engine management.vololiberista
