In case any one is interested I did manage to lockup RFX and the Editor. Had to go to task manager to close them out. Using Windows 7. I had both open at the same time, so that may be the issue. Not sure how to make changes on the planes I import in. But have found the Hanger 9 Pawnee imports in and performs perfect. Also the Top Flite Elder Hp Imported perfect and flew perfect. Neither of these planes needs any changes.
