I built a co-axial gyro from a converted fixed wing fuselage. I used the same hub arrangement as Al's but used proper sectioned blades instead of the flat paddle type. The blades had an incidence of around +1 degrees and self started by angling them forward 45 degrees before the take-off run. It flew superbly and both rotors appeared to be rotating the same. In fact it flew so well that i am currently building a small version using an .09 size engine. Maybe my model was just a fluke and this new one I am building will have the 'lazy' rotor. We will see !!
