I have built two Auto Gyros now and done some testing. The second version is longer and balances easier. The first was nose heavy and I didn't want to add dead weight to the tail. I have tried two, three and four blade rotors and varying airfoils, angles etc...
The latest version has four 3" wide blades that can be trimmed at the field whereas the others were fixed.
My goal is to make this a one board model, easy to build with common items, and easy to fly. It will ROG smoothly even with no wind.
The Mig 15 has undergone several design changes and I am settling on a very easy build sacrificing some scale accuracy to the fuselage. From 6 feet away you wont notice the compromise. I scrapped the 55mm EDF design in favor of the 30mm EDF because the plane was getting too big. The 30mm version starts with a common 1-1/4" PVC tube you can get at Home Depot. Wrap with paperless DT foamboard and from there a Mig 15 and F86 emerge. I will try rudder only but it may be a "yank and bank" elevator aileron control is better.
The new design Mig 15 has a span of 17" and length of 17" The electronics include a 2.4g micro lite receiver, 2.5 g servos and a 12A ESC. Thrust from the 30mm EDF is 80-90 g so the target weight is 4-5 oz. The hope is this will be a docile jet and not a bullet.
