I'm rebuilding an arf and am looking for balsa stringers. I have found the 1/4 x 1/4 stringers but am having difficulty finding the "triangle stringers". I orginally thougt the triangle stringers were just 45 degree angle but there not, the angle is more acute. The cross section is more like a 45% stringer ripped in half lenghwise. So the angle of the pices might be 27% or so.

Kind of hard to describe in words

The reason I'm posting this on the building site, is I'm hoping you guys that build kits would have a good idea of where one could find the balsa stringers.

Thanks!
