New Design: Lunar Max
I have come to like this vintage look in a design with a paper transition housing the motor mount that extends past the main body tube. This look however is bad for the static margin in shorter designs. I fixed the problem with larger and longer fins that extend past the motor mount itself. I also felt that the fin root needed added strength so I added two 1/8 inch balsa stripes to each fin root edge for reinforcement.
Enjoy and Thanks Again, JP
