          I think the 2 side rotor blades are for show onie... the propulsion still needed the gasser motor. Am I rite?

            Propulsion is from the motor, the rotor blades spin with the induced angle of attack and provide lift for the entire airframe.

            very unique and a nice peice of work

              Yes it a nitro engine OS max 25.
              got this kit long time ago i think 1977

              cheers

                Yes you are right it get lift from the 2 free rotaing blades.
                it can hover and land like a heil also.

                cheers

                  I bought the plan for similar model called Gyrace, better looking than this I think but never built one. The drawing is with me for almost 20 years!

                    Just wondering, do the 2 free rotating blades act something like autorotation as in heli but with fixed positive pitch ?

                    Its a Great day, lets fly, crawl, and fight.

                      Yes, they are like auto rotate in the heli, hence they also in negative pitch. Type to imagine the rotor is like a glider wing, and the glider is flying round and round, in this case, you have 8 blades = 8 gliders flying in the circle.
                      I used to crazy about autogyro many years back before I started heli. However, I never manage to bulit any autogyro completely.
                      Btw, the rotor (8 flat blades)as seen in the pic is not efficient enough to fly, thus the aircraft still needs some wing. Whereas other design, the blades are with profile (thin clark-y is commonly used) and can fly without the wing as in heli.
