I have built 3 Snappers over the years, the first one was Cub powered, and flew OK. The second had a Wen Mac and silk covering - what a toad. The third was quite recent, and I did EVERYTHING to lighten it up - scratch built with light 1/32" balsa, Holland Wasp engine, balloon tank, Litespan covering (no paint required, lighter than Jap tissue, but tougher) and clear epoxy on the wood.
Would you believe 4 ounces? 37' of .008 solid wire lines. 5x3 prop. Completely capable of a competitive pattern. Loved that model to death! I put an Atwood Shriek on it for one flight. Whoa Nellie! That puppy came right back off again.
