My third autogyro should have a two-blade rotor. The models of Jochen Köster cover all designs. The Micromum V8 is the two-blade version. As a modification compared to the original I added a controllable rudder. To be able to observe the rotor speed I attached a contactless RPM sensor provided by Jeti.
Unfortunately the forecasts concerning the controllability of two-blae rotors on models came true. I never got the Micromum really in the air until it was damaged too much. I'm thinking of building a three-blade variant from the remains I still have. We'll see.
