A good example of this is The Alpha Bleu F4U-7 Corsair package
If you mean the NorCal updated version - well I have SP2 & fly that without any problems whatsoever that bothered me - all gauges seemed to be working - everything fine - beautiful aircraft - works beautifully in FSX SP2. I checked it out when it was uploaded as I'm a great fan of the Corsair .. & took the screenies for the page.
Perhaps you might like to be absolutely specific about what problem you are having with a screenshot to demonstrate & someone may be able to help.
Yes, I am referring to the NORCAL update. Don't misunderstand, the aircraft flies just fine in my sim, the gauges are all there and the model looks great ... none of those things are the issue. The issue is: when I install it, NONE of the aircraft in my hangar have the engines started when I load them into a flight. Then, when I try to start the engines (CTRL-E) on those aircraft, some will start-up and some won't. If I delete the Alpha Bleu Corsair from my hangar and delete the files they say to load into my effects and gauges files, everything goes back to normal. I do not think a screen-shot will help with this issue.
Pete, are you using "Acceleration" also or just SP2?
