I noticed the same thing in a slight breeze. The heli would not respond to forward cyclic input and almost hit me in the face. I see the servo horns are cut off. I was thinking the same thing but was concerned about blade strikes cause the blades cone slightly at high rpms. It's worth trying though. I just ordered some Xtreme blades, they are supposed to make a difference because they have more cone shape to them. Seems like it's gotta be pretty calm to fly the V4.
