Purchased new, plane flew fine at first. HOWEVER, once in a while the rudder stops binding. I have openned it up and tested the servo and all seems fine. It binds right up with my Spektrum DX 6i again and then sometimes in mid-flight decides to quit. It flys fine, you don't really need a rudder, you just walk up to it if it won't turn around on the ground. I would NOT put skis on this thing! Includes THREE batteries and a DC charger.
