When placing C-130J in 2D editor, and selecting SPECIAL > FLYING, plane flies normal.
When placing the same plane using the EDEN editor and selection transform> move to flight altitude, plane crashes, doesn't fly, drops to the ground. (I don't see the SPECIAL >FLYING option, as you do in the old 2d Editor)
Doesn't happen with C-130's created by other authors (Sabre).
Doesn't happen with other CUP planes:
