I agree, it flies well.

Maybe not a mistake as such, but it's a weird way to construct a plane in my opinion. I wonder why they changed the incidence. Anyone know? They changed a lot of other things as well. Tail servo locations, servo trays. Also, aileron trailing edges align with the wing trailing edge now and the cowling seems to be closer to the wind leading edge on the old ones as well (maybe the old version was tail heavy).
