Instead, I make a series of simple and inexpensive tests first, refine the idea, then finally use it on a model. Finally, I incorporated it into the "Eliminator 2" vertical fin, and on the other wing and tail parts. I will liken designs like these to the last gasp flak that cessna and piper were filling the skies with insisting that huge heavy aerodynamically dirty planes were ideal while the kit plane folks and the european theater kept advancing with new materials and ever cleaner slippery cost efficient designs. The wing won't hold any fuel - the 30 pounds of fuel is located at the center of gravity. we have easy going and cheaper wood techniques, just the design is less curvy or takes more time to build. If the foam rib is inside a stressed skin wing, the stressed skin is effectively the cap strip and the foam can be bonded directly to it.

The foam is weatherproof, easy to form, and less rigid than Depron, but more flexible. Then calculate the area you will need given a length to chord ratio for your flight regime. The foam is used to take small shearloads and support the primary structural element in absorbing tension and compression loads. Youre second design looks much improved though you need to redesign the gear and tweak the weights and balances. check on Goat Glidersslow and low flying on youtube, there is a guy who does it,..and as ULs are asked for slow flight anyways, why using naca 64xxit,s for fast flightand yes, i went through all options and all calculationstook me a whole year! 4 years ago When they were correct, we used our vellum patterns to transfer the patterns onto the actual fuselage plug. he did a great job for someone with such lack of information/knowledgei even got my firts ideas from himnow 2 yrs later and hundreds of hours of research i know bettersorry.the best stuff he explains is the balance!
