My father built and flew a Sunray when I was a kid too. He flew in an area of north Phoenix, AZ called Paradise Valley back in the late 70's. I remember a Chauncy and a guy who flew a very scale Dauntless forever flying out there too. Anyway...my dad was flying the Sunray one day and the receiver battery disconnected. The plane hit a pile of construction concrete in the ensuing crash and was pretty much destroyed. He still has the remains in his hangar rafters. I'm going to have to get his plans and build one now after seeing this thread. I'm also going to have to find a Donald Duck to put in it like dad's did!

I take a picture of the remains and post them up here. I have the original instructions just not the plans. Dad still has those. I do have some original Hyperbipe plans though...hmmmm, I wonder........
