I use $ store foam i remove paper then $ store clear tape & add KF on top at about 30%. I use CF first but found out on big wing 1/4 round spruce work's better & lots cheaper. use wire truse on bottom.

I hope you don't have pitch problems in flight control. Will be interesting to see how slow it will fly. If you put split airlerons on the tips it can fly around itself!

Take a long skinny piece of foam. hold it in the center and let it go, see if it flips all the way to the ground. A split airleron is like on the stelth bomber.

The disadvantage of a very long wing and a short fuselage is stability. The idea of dropping a piece of foam was to demonstrate how it has the tendency to flip and flutter to the ground.
When you do get it to fly, a split airleron may help you turn better than trying to bank and turn with such a long wing. I trust you understand the concern for the ability to control your design effectively. I ware glasses so an extra four eyes could be helpfull.
