Thanks for your interest. The blades are 22 1/4 each. Weight is about 5 pounds. Engine is an LA .46 with a 10x6 Vess prop and the fuselage is 38" long. This gyro was hand built including the blades. The gyro flies very well slow or fast. I have done two or three loops with it ,but it's just too nerve racking. The aileroins and elevator are controlled by the head and I use rudder as well in the turns.
