RE: Balsa USA Super Cub Build
I've also just picked up a 1/3 scale Super Cub in the bones. Just wish the builder would have built it with the optional flap/aileron scale kit, but he didn't. Not a big deal, though. I'm not going to be competing anywhere with it.
Thinking about what size engine to put in there. I have a DA-50 not doing anything right now. Even thought of a DA-60. I like the idea of a two-cylinder 50-70c engine, but not many "reliable" or well-known types out there. For a twin, probably have to go with a 3W. Not sure about the Rotomotor or any other twin of similar size (the old "get what you pay for" advice rings true here!). Really won't need an engine 'till later this year or a year from now (Toledo 2013!!).
White or Linen Solartex, with marroon or green (standard Super Cub) trim, will be the covering of choice. I've cut lots of pinking tape with a quilter's pinking cutting wheel...works wonders when using a straight-edge. Make any size in any quantity you want. Rustoleum or latex house paint will be the final finish.
Going to pick up the 1/3 Cub/Super Cub gear from Robart at Toledo...in just over 10 days!! The Cub gear fits both perfectly, per my call to them, and they'll have some there.
No hurry on this one, it's going to be my next project for next fall/winter.
