My vision flies fine, no snapping. trust me, I have done every slow or stupid thing with it, and it loves the elevator buryied. I would not own another gas plane that does snap, its no fun.
I have the Vision and the Double Vision. still workin on the DV, hopefully by months end it will be done.

I have flown the EF yak, and think it flies better overall, but, you can buy a Vision, you cant buy an EF Yak. The WH stuff just seems to portly, seems like a nice company and all, but just overweight.
