Hi Dave, how are you? I am happy to hear from you. I was working on a Kellett K2 at 1/5 scale and a Cierva DHC24. I have them on YouTube and I have also uploaded other of my autogyros for u/control (latest design) in the other autogyros forum. Now I have just repaired my Helix, I had an almost complete breakage due to a failure in the switch connector. I ordered a new fuselage from Germany and it is ready. The PCA 2 continues to fly beautifully as usual. I just replaced the SC AR91 motor with a Saito 100. I am going to use the SC 91 in a new 1/6 scale Kellett K3 model. To tell the truth, winged autogyros fly without problems and with my age I see them better in flight.
