Bill,
Don't know what you're intending to do with the Twister wing, But personally I feel the Chipmonk wing is a better wing to work with. This was used by MANY folks during the 50's and 60's for those Nobler look-alikes! If you recall my last disaster at the Criterium, My profile piped force was built around the Chip wing. Per instructions (and plans) from Unca Mikey. Was still available a couple of months ago...
