Excellent video Carlos! As I crash rather than land the plane, I was happy to find some big pieces of EPE packaging foam at work 1000x150x80mm and I am now cutting out a fuselage for my home made foam wings. My wings are folded 6mm foam which I think is made in Poland and sold in the UK as Kilma under floor insulation. It is very similar to Depron but is available from Screwfix outlets all over the UK There is also a website called efoam with a co and a uk that sell EPE as Ethafoam.
