I have another patch ready to submit with xml indents and tabs fixed and consolidation of redundant sections as well as alignment of the propeller spin axis with the spinner axis. I believe that the position on the ground should be totally determined by the gear compression forces and the mass and cg. I.e. it will correct itself once we implement correct gear compressions. So don't mess with rotating the 3d model. At least let me try to get it right with gear compressions. One other issue I see with the 3d model and the textures. The way the cuts in the textures is done, one has nearly vertical surfaces on each side near the bottom edge of the windshield. This results in severe stretching of the textures on each side below the windshield. This is fairly obvious and needs to be corrected. This again involves a lot of work. Does the team think we need to fix this for the liveries before the next release as this is the default ac?
