Good day Ed, The Skybench (he produces several versions) of his 'Bird' series of kits just kinda, sorta have the outline of the BOT, the two could be compared together as 'stand way, way off scale'. The outer panels of the wing are much longer in span then the inner of his kit vs. the org. The opposite is the case of the Skybench kit and I doubt the airfoils are anywhere near the same either tho I don't know for sure. I built a kit BOT a couple of years ago and I still may have useable airfoil plans to share . . . doubt it tho, but Il'l take a look.
