4. Rocket is 92.2” in length, 4.5” in diameter (OD)- 4.375” (ID)- and weighs 29 lbs. Uses machined fin brackets, motor retainer and tail cone. Recovery System is Single Ejection (CO 2 )/Dual Deployment Overview (Project/Vehicle) 4

5. Fin Bracket Allows for easy replacement of damaged fins Allows experimentation of fin design (to alter the CP and therefore Static Stability) CNC machined aluminum – No epoxy or other permanent bond Screws into fin and through body tube 5

6. Motor Retainer Machined Aluminum forward motor retainer Attaches to motor casing Screwed into airframe – No epoxy or other permanent bonds Acts as an Av bay aft bulk plate 6

7. Tail Cone CNC machined aluminum aft motor retainer Reduces drag up to 50% for subsonic flight [1] Threads onto aft of booster section – No epoxy or other permanent bonds Opens up more room in airframe 7

8. Structures Rocket Flight Static Stability – 1.4 Current Simulated Mass: 29.3 pounds Mass Margin: 2.6 pounds Predicted Drift 8 Predicted drift as a function of wind speed for the current mass estimate (483 ounces).
