Just Google Flite Streak. They were a Top Flite kit. One of Sid Axlerod's first. There are images etc that pop up. It had a milled leading edge that was hollowed out that would be the biggest obstacle to scratch building one. One might could save some weight by molding a leading edge? Then use a nylon tank and carbon pushrod. I bet you could build one at considerably less than 26 oz with a modern 25-34 and today's materials?

The plane could be flown the full pattern but was not smooth like a Nobler or even a Magician. It was originally sold as a combat plane but I liked them as a control line fun fly plane which they were better suited for.
