Not sure what's going on, but full throttle (using both Seitek throttle quad and keyboard) only gets me about 2200rpm on the ground (should be closer to 2600, no?). FSX sp2 accelFTXGEXUTXREXA few other a/c addons Any thoughts? Thx!

Elevation?

Elevation is important, as a normaly-aspirated, fixed-pitch-prop airplane only has MP available to it, per the pressure altitude... But also, as I was taught, a real 172 with a standard cruise-prop, has a go/no-go RPM at throttle-up of 2200 (at sea-level).. and it will increase as airpseep increases.

I'm flying from KMMU, so it's pretty low. I did find this: http://www.gameskb.com/Uwe/Forum.aspx/games-flight-sim/699/Cessna-172-Max-RPM-Problem Also, after playing around a bit, I'm pretty sure it has to do with the automix - when it's on, I'm getting about 2300 on the ground. Off, closer to 2100. So, not sure if my own mix setting is off (I was pretty sure it was at full rich) or if FSX wanted it a little leaner. I'll keep playing....

FSX defualt 172 without G1000

 

Have same problem with Saitek TPM. Will not cut off or reach full power. Worked fine in XP but am now using windows 7. Can cut off power and mixture completely only with keyboard. I was able to cut engine off in XP with throttle idle and mixture pulled back. All other controls work fine, Yoke, Pedals, Trim. Pretty frustrated! Any suggestions? Thanks.

Perfectly realistic and that is a sign that you are getting full power. You can't turn 2600 RPM on the ground in a 172. The resistance of the air is going to stop it at around 2300 RPM with the engine leaned for max RPM.

Try pressing 'h' for carb heat. This works for me depending on the weather...
