as usual, i still beleive that with enough CF i could slice up your foam with my balsa, but still, for the sake of ease, i recomend the foam too. (upon getting some i relize just how tuff this stuff is, this is not your regular styrefoam stuff this is sturdy.)
although i stand that a CF wing will tear you apart but thats my oppinion and will never change aeven afteryou tear my CF wing apart
(yes im stuborn)[:@]
