Just for the record IMO, The Sig King Kobra was never sold as a pattern ship, but a sport flyer. It was designed for a 60 size motor. It had a tricycle gear and lines of a Jet.
But...I Built one from a kit and moved the main gear forward and used retracts. Dumped the nose wheel. Added 1/2 inch to the Height of the rudder and added 3/8" to the length of the rudder control surface. Split the elvator and used a split wire push rod, and pull pull for the rudder. Installed a Rossi .61 RE with a tuned pipe down the top of the Fuse with one support clamp/bracket, no cowling.
I tell you this, in 1981 I was flying advanced with the best of them using that plane. I was told numerous times that the King Kobra was not for pattern Until they saw it fly.

I suspect that you would have won or placed high while flying any four channel model, Mike. Piloting skills makes the difference. I know a fellow that used to win in the Advanced Class regularly while flying an oil soaked OS.40FSR powered Sterling Fledgling. He was one of my local heroes for doing so.
