North American P-51D Racer 1

I have the Acceleration package installed, So I'm using Microsoft's release of the Mustang. I do not have failures set at all, not even random. I'm using full realism.

For some reason, when I fly the Racer 1 edition of this plane, I have an engine failure, I see a lot of white smoke, nothing black. Sounds like the engine is misfiring (popping) and I lose almost all power.

I've tried adjusting the mix to about 50%. I'm taking off from KIGM so it's over 3,000 feet to begin with. I keep the throttle low after take off.

Not sure what other info I need to include.
Has anyone else had this problem? Any help would be appreciated.

After turning down the realism settings, do you still have the same problem?

I gave that a try and the plane works fine. No engine failure. So what could be causing the failure with the realism on? I must be doing something wrong.

It's not you, One of the first things I noticed when I bought fsx is when you do have the settings up all the way something almost always breaks down after a couple of minutes, I fixed this by having the settings around 1/4 to a 1/2, and seems more realistic.
Infact instead of calling it 'realism' they should have called it 'time till everything blows up in your face'

By the way welcome to the forums
