Starship
By: Kevin Johnson
Winner, April 2003 Design of the Month Contest!

Kevin's entry is a creative use of parts not normally used in this manner (the centering rings used as external detail).  This Starship is designed to use 18mm motors. 

"Here's an entry for April. I haven't buitl it yet, was just noodling around with some ideas in RockSim (file attached).

Misc parts:

12" Parachute
Paper transition- conical, BT-50 to BT-20, .5" long
Nose wt. (RockSim says to add 1.5 oz could prolly get by with less)

Consrtuction notes:
There are a lot of centering rings used in this rocket; 2 are for the motor mount, 2 to join the BT-50 parts to the center BT-20 tube, and 3 evenly spaced on the center tube.

I'm thinking it would be much simpler to paint all the parts before assembly, especially if you want to use a contrasting paint scheme like I've pictured.
