Pieces are 8cm, 5cm, and 1 cm thick. I think they will be great for fuselages and more.
They didn't have nothing thinner, so I went to a hardware store and bought a pack of 3mm and 6mm thick foam, 5 and 10 euro each.
I still have to figure out a source of wood. Balsa is not existent, so I'll be using poplar, birch and lime tree.
Naturally, I dont have a band saw ir circular saw to cut wood, so I'll have to make one :).
A small lathe will be required also, but.... Later.
