I was also surprised at the amount of coupling on my Comp ARF Extra - neither my Midwest nor my Hangar 9 required anywhere near as much mixing. I have seen a TBM 35% Extra fly during the past summer's IMAC season - it flies slower than the Comp ARF and looks very solid. The owner did have some issues with some areas being too lightly built - like the blind nuts for the landing gear pulling through the plywood plate during a normal landing and poking holes in the wing sheeting when taking the wings out of the box. I heard a rumor that they are using slightly stronger wood now.
