This is a sweet flying plane!
Lipo is 800 to 1000 mah 3s
Here are my sketchup sketches. The airfoil is not correct in the sketch.
It has a 15 x 6mm balsa ( depron should work, too) spar 60mm from leading edge and the depron is bent over it.
The fuselage is a very simple box with a ply firewall and only one more depron spacer at trailing edge. The upper part of the fuselage is just profile shape.

The fuselage is a box/profile hybrid.

Forgot in the sketch: Wing chord at wingtip is 140mm + 50mm aileron, Spar height is sanded to 14mm at tip.

How many sheets of foam did it take to build this? How much 3? How much 5?

Not sure about this - about half a sheet 3mm for wings and fuselage and some scrap parts 5mm for the tail and ailerons.
