HPH Hop
I used what was available. May have to go back to the DB. Design is for a coaxial craft. but I can modify all energy to single rotor.
I had hoped the weight would be an advantage to a point. I realize the Gamera, Yuri, and Da Vinci Crafts all were under 150lbs plus pilot, but they had no pitch control. The operated at full pitch from the start. No inertia, no storage.
