all i need now is the balls to try it
Graviman and peter RB. Just a clarification! One of the photos posted shows the mk 3 machine which has a ring rotor device mounted above its normal pair of blades. This was done just to expose the ring rotor concept to interested parties at an airshow. The actual ring rotor will be fifteen feet diameter. The Ringrotor is something i have been working on, to provide great inertia with a minimum weight penalty. The Mk4 has been designed so as to be able to retro fit the ring rotor when airframe and drive systems are proven.This is why the tailboom lenght is adjustable. The current engine is a Yamaha FZR. I will post some closeups of bits you mention. Thanks Bug.
