Conclusions so far:
The 3M77 joints add 0.1 to 0.15g per joint.
The middle of the foam slab was lighter (by approx' 4g
for these cores)
I'm not going to make the theory values as I'm already
at least 10g overweight, foam density ??

The following table was to be completed as the build progressed, but
competitions wait for no man and so a lot was missed. Bottom line was a lot too
heavy but the wings fly really well.
