Tri-Star
Overview
Tri-Star is my first-ever attempt at building and flying a rocket with a cluster of three motors. Tri-Star is capable of flying on three of any 24 mm diameter motor and can loft a slimmed-down version of the Project 767 instrument payload. The rocket’s name is a tribute to my home, the great state of Tennessee, which has three stars in the center of its flag that represent the regions of the state: East, Middle, and West. The red, white, and blue color scheme of the rocket also comes from our state flag.
