Hi guys, This picture was taken from the June 1950 issue of Air Trails magazine. I had built the stand off scale Cierva model from three-views. It had a Torp 29 for power and flew both free flight and u-control. I had seen some autogyros at the Kellet plant in Willow Grove while flying with the Navy. I had no idea how an autogyro flew but I eventually got it into the air and flew for several years. The trick was 2 or 3 negative degrees incidence in the blades. The bearing was from a ball bearing mica cable guide. The rotors were built up fo balsa and covered with silkspan and were free to bounce up and down and fore and aft. It was a super smooth flyer and needed no control at all. I later became editor of Scale R/C Modeler for over 10 years and still love the autogyros. I am about to build another one first time in 60 years. Norm
