That's the way Brad!
Go get em.
I met a guy in the LHS the other day who makes his own blades for the BCP--flatties, he uses balsa stock, a planer, a bandsaw and a sanding block, the plastic bits from some old blades, and just leaves them uncovered. Must cost about a nickel apiece, and can't be any worse than EFlite flatties. Wouldn't be much harder to make symms...
.
I make mine from 1/8"x3/8"x36" Spruce, for the leading edge, 1/8"x1"x36" hard balsa for the trailing edge, and a 1/32"x5/8" x36" cap over the joint to bring the sandwich to full depth.
Roughshaped with a sanding block, and sanded to contour with a molded (Bondo) sandpaper block.
Get 3 blades per 36" piece... works out to 65 cents each.
The blade holders come from broken blades.
