The Kraft model isn't bad but that Gwinn..... oh my......

If it was an area limited event then mono would be the way but with a span limit the biplane could be a possible winner here.

The high winds would mean that the model may not do well with the end plate interplane panels but then again it might.

I think I'd be tempted to keep the thrust line centered between the wings and the cargo bay between the thrust line and the lower wing. Keep the CG a touch low in otherwords but not TOO low or other oscillation factors may enter into the mix.


Because of the massive wing area of as much as 2000 sq inches I'd be careful about using the super high lift airfoils such as the Selig 1233. You'd have to check the charts and crunch the numbers but with the massive amount of area you'll have I suspect you'd be better off with a slightly lower lift and lower drag airfoil. Bipes are pretty draggy anyway. And if it's that windy there then a little extra speed would be a very good thing anyway.
