Thanks Kevin for the input. The Apogee site has some Harpoon designs,
the 2 stage version. I may be able to modify one of them. I built the
Harpoon stock but as you know TLP doesn't tell you where to place the
one long lug they supply. I have just one centered between the big
fins. My next step is to add a smaller lug at the aft end of the body
tube and see how that works.
