OK, here are some rough dimensions.
The BT length is 3"
Dowel length is 8"
ThefFin/dowel brace span is 3/4"
The fin/dowel braces are notched on the leading edge to fit the dowels. The notch is from the trailing tip towards the top of the root edge and is 7/8" long. The notch is just big enough to fit the dowel and be flush with the unnotched part of the leading edge.
The body tube decal wrap is 1 5/8" tall.
