since the competition grade balsa is so difficult to get nowadays, do you thing is there any parts of your model that could be made in depron, thin foam or any other alternate material instead?
Hi Eduaero,
I suppose you can replace the built-up wings and stabs with foam core construction. The shape would have to be modified a little, since you can't have a curved leading edge on the foam cores.
For the fuselage i don't think you can replace any of the balsa frames with depron, at least not without increasing the thickness significantly to have the same strength. This would require a complete redesign of the structure in the area of the depron parts due to the large number of interlocking parts.
