4 Stars can be coaxed to do a little 3D. I have a 120 sized one and I hover it. It weighs 13 pounds and pulls out with a 3000 turning a 19x8wide. I havent been able to maintain a good harrier or elevator (could be my skill level). I can get the plane into a harrier attitude, just cant hold it. I can get a sorta-harrier-slow knife edge flight fly by; thats about it.
