My friend and I like the EP Sportster that he has so we thought we would scratch-build something similar.
First we ordered a box of balsa from http://www.solarbo.com/
which is a new supplier to us, my understanding is most their business was supplying Chinese Arf builders. The balsa looks pretty good to us and the service was quick.
We then went to HomeDepot and got some blue foam to cut cores from.
These are the pictures of what we've got done so far...
The first picture is my foam cutting set-up.
The second is the core as the top is taken off. We are using a symmetrical airfoil.
The next two are pictures of the fuse and tail-feathers.
