Sorry Ron, I have been hearing about and been interested in ultralight tractor gyros for quite a while. Tim Blackwell built my first gyro and began building the Gyrodeere in 2004 using composite frame tubes and several other interesting design ideas. It had a complete frame and seat, the engine was mounted, rotorhead and control tubes in place, and stalled because of employment issues. Many interesting and innovative ideas left hanging.
You've been posting on the forum about your Rotorscooter build since 2007, also with several interesting ideas. After being on the forum for a while and IMHO, it seems that the encouragement of the forum people following the build often helps to get the building process "over the hump" and into the air. I'm sorry if I seemed pushy for information, I know very little about the intricacies of patent law and was only interested in seeing something new and different take to the air.
