Hi Karl.The model was destroyed after it was sitting in my workshop for years. I created plans from plastic kit I purchased. I do not have original plans. I know that whole model was built from the Styrofoam. Sorry for quality of photos but that is all I have.
Here is photo of my other Autogyro. Scale model of CIERVA C.8L-II with 76” diameter of the rotor (1:5.5 scale). The model was built from the balsa, plywood, steel and carbon fiber. Flying weight 8.5lbs. Power AXI 4130/16. Will be test flown in the spring 2007. Some tests were done already. The rotor was tested on the windy day to find out if there is issue with blades tracking properly and if there is vibration. There was no problem with that. The rotor generates lot and lot of lift. The rotor mast can tilt 7 degrees left to right with heavy duty servo. The advanced blade can flap upward by me using thick wall carbon fiber tube for main spar. The downward travel is restricted by steel cables. I have seen full size C.8L-II hanging in Paris museum.
