DEAD STICK!!!!!! Ha, got ya.

Does anyone have any ideas about where one could acquire balsa dimensionals (1/2x1/2 - 3/4x3/4 - etc.) with lengths up to eight feet? Having committed myself to a 30% build, with determination to replicate all facets of detail (aside from metal tubing), I have found myself stuck by the inavailability of lengths of balsa. I flinch at the thought of splices, laminations and/or other means of acheiving length. Anything?
