RE: Extra 300s or Edge 540
Get an extra 260, it is mid wing, low knife coupling and good at both pattern and 3d. Flies like a pattern ship almost. Good stuff.
Now not to be picky or anything, but Stinger, name one 3d manuever that doesn't involve a stalled wing. Also, full scale edge 540's can pull out of a hover, so I guess 3d flying could become full scale stuff.
