Flight of Model RocketFlight of Model Rocket
The Trajectory of a Rocket is dictated by:
Atmospheric Conditions (Wind)
Aerodynamics
Propulsion
Recovery
Launch Angle

CONSTRUCTIONCONSTRUCTION
GENERALAnalytically determine Center of Gravity (CG) and Center of Pressure (CP)!
MOTOR MOUNTYou are not allowed to glue the motor into the motor mount or to perform any
physical alterations to the motor!
Motor Stop (front)
Motor Retainer (aft)
Motor Spacer for F42–Motor
FINS
RAIL BUTTONSOne rail button must be installed at the Center–of–Gravity point.
PAYLOAD BAYSPayload bays for altimeter and beeper are to be installed in the nose cone.
Payload bays have to have front (FIXED) and aft closures (REMOVABLE)!
