Right then, took ages for me to actually get around to it, but I can confirm that the file name seems to be the issue, if you can really call it an issue. Changes engine specs in Plane Maker and then saving over the original file worked a treat, whereas saving as a new filename didn't work at all. Whilst we're waiting for the new version, I've found that doing the following small steps made the flight characteristics much closer to the one I fly, if anyone wants to do the same: Weight -> Empty weight 1220 lbs Engine Specs -> Max Throttle 0.8 ; Idle Lo and Hi Adjust 0.75 ; Engine Redline 2,550 rpm ; Max Horsepower 108 bhp I found that this adds a bit more weight, brings the engine more in line with the O Lycoming rather that the L, and brings the engine within more normal limits (~500-700 rpm idle and ~2,550 rpm full throttle). Soooooo......when can we expect the all new, singing and dancing official update Airbus? And any chance they'll have working circuit breakers??? :-*
