Hi, I was recently given a pattern plane that needed some TLC. I think it is a SIG King Cobra, but am not sure. The plane is equipped with an OS .61V engine running a tuned pipe about 12 inches long. The plane has air retracts, don't know what brand. I recovered the fuselage and painted the wing. I flew it once and decided the plane was way too fast for me. I like slow flying fun fly types of planes. If interested, a super deal can be made as I have no use for the plane. What is this monster worth....I have no idea. The plane is located in western Iowa. Thanks.
