In FS9, turbo props idle power was very high and the aircraft would taxi by themselves at idle. There was a fix put out to reduce the idle power (as I remember in the "devices.cfg") so the aircraft would not taxi at idle. I have noticed the same problem in FSX. Does anyone know if there might be a fix similar to the one used in FS9. Don't see a Devices.cfg and I looked in the Controls.xml and didn't see where a fix might be applied. Thanks in advance Brad

Set your conditioners to low idle when taxiing. That should help. ;-)

I've noticed the 737 will slowly creep forward too. What should I doto stop that? Is there a way to feather the engines and if so, how?

A 737 will actually creep forward (and possible accelerate) on relatively smooth and level tarmac, at lighter weights with idle thrust IRL.
