Good idea with the card stock for fins Craig. Where can I get some of Carl's cardstocks material? I wonder if this cardstock is compariable in wieght to 3/32 balsa?

Also Craig, notice the difference between Scrappy and Thunder Strike designs. The center tube in Thunder Srtike is classified by Rocsim as a regular BT and not an inside tube like Scrappy has. I needed the center BT to be a regular BT to be able to put the fin set on the center Bt. It took me a long time to figure that one out. Just thought you might be interested.
