Exoman: Can you please copy and paste the [Piston Engine] and [Propeller] sections of your Aircraft.cfg file, please? Thanks.

The problem is very common and easy to fix - usually you need to lower the 'Beta min=' value. Try lowering that value and see the effect. If you have trouble, post those sections and I'll fix 'er up for you.

Oh - and welcome to SimV!

i have a similar problem. i have to move my throttle up about 25% before it starts to effect engine rpm, i have throttle sensativity as max and null zone as 0 in the settings on FSX.
