Hi guys, I'm stumbling into problems with a turboprop im working on in fsx. Normally in real life I fly piston twins, and from what I gather I can basically throw all that out! Evidently mixture is not the same, and the prop lever doesn't control the prop, except for when it does...

According to what I know about real life turboprops so far is that as the engine spools up during start, it briefly surges over your throttle setting before it settles down to idle. This seems to happen on all the turboprops I've flown in fsx. Good!

The problem I'm having is that the plane I'm working on doesn't weigh much of anything (picture an Extra 300 with a Kingair engine) and that initial power surge that, in a kingair or caravan would be a minor thing, threatens to put me into orbit unless i set the condition lever at low idle (which I assume is the proper procedure anyway).

My startup sequence with the condition lever at ground idle is fairly fine and uneventful. But why is it that I can start up the kingair and caravan and even with the cond. lever at full,...and they just dont move on their own? I know they weigh more, but I don't think this can be simply because of that. If it is though, are there any settings I can change to make the plane slightly more forgiving when the condition levers are full on the ground?

The biggest problem (and why I've never released this plane) is because when i set the condition levers to full on the ground, it will takeoff eventually.

Any idea's? Other than stick with pistons and jets?

True. But I should back up... It's a concept plane, there is no manual and only 2 aircraft in real life that I know of that are similar and they were actually converted from pistons.

I'm actually in the process of writing the manual - for my own use at first, but when I get it wrung out it will be probably the final manual if I figure out the problems and release this. It's always been a problem project, so it doesn't really break my heart not to release it. It still needs panel and model work, but those things I can do in time... but I'm to a point where the ground idle issue is the only thing annoying me and preventing me from completing it.

There has to be a way to meddle with ground idle.
