I thought 3D flying was for Heli's?
Imac flying is harder then hovering...i dont have a problem with either at our field, as long as its not done over the pits..like a lot of trainer I see...
I say if people want a challange then go try to fly a straight line, in the wind, both ways...if that isnt enough add a 8 pointer with a snap and a half in there...that oughta give them a little respect..anyone can hover, hell my 2.5 year old can hover
