Around the net there are various sites that discribe how to cover a Zagi without packing and strapping tape.
One scheme know as the smiley spar, replaces the strapping tape with a thin carbon spar. The it's covered in ultracote or something similar. The idea being to reduce weight.
I had a possible variation on that theme;
What if I took the stock core, and bagged carbon fiber cloth gores on the upper and lower surfaces of the core using MGS epoxy.
A) would this offer enough structural stiffness?
B) will the carbon stick to the white foam without fiber glass?
C) what if I added a a layer of light cloth on top of the carbon?
Finally, I plan on adding some hard balsa or spruce (whatever I can find lying around the shop) to the trailing edge of the airfoil to add some additional stiffness.
This is purely and experimental endeavor to see how light I can this thing. I want to optimize performance but stick with stock battery/powerplant setup.
