Did'nt know if anyone had an opinion on this.The new and improved version will take flight soon.The Rotating wing is 6ft. tip to tip and 6 inches from lead to tail edges.The picture posted is of the first prototype 4ft. span 3inches lead to tail edges with very weak motors! Roll over Sigoski,This is the way the Helicopter should be built.It is a more afficiante way to turn it and loosing the tail rotor in the process?
