Here is another design that keep growing over the months of development. I think it started out as a small lander and just kept growing into a sleek, long design. And yet, once again, that Tau nose cones really finishes off this bullet like design. The split upper and lower launch lug method I have been using seem to work well when the CG is in an difficult place. Also seems to be a good method to help hide those ugly launch lug stand-off fins.

FYI: The numbers after the design name is just for me keeping track on all the designs on what version I am working on and like the best.

Enjoy and Thanks Again, JP
