Do not have the ribs plotted. I may do it one day. It would be a simple process with compufoil and some airfoil parameters. Its probably a modified NACA or an Eppler airfoil or a variant of one.

The laser cut formers will run you about $35-$40 a set shipped, . Nice work, and great balsa.

Mike , post a pic of the of the multicolored typhoon you showed me in Huntsville.(the before pic, not the after) Thats the prettiest one i have seen.

BTW MIKE. Count me in for the 3M head for the OS14 you wrote me about.
