Thrust to Weight Rule

• If your rocket weighs too much for the motor then the speed off the launch rod will not be enough to let the fins work.

• If the fins do not work the rocket can go unstable easily and become a hazard

• The Thrust to Weight Ratio should be greater than 5

• The thrust is the second number for the motor code. For C6-5 motor the thrust is 6 newtons

• Note: 1 lb equals 4.45 newtons

• minimum thrust = (wt lbs * 4.45) * 5

• So for a 1 lb rocket you need a minimum thrust of 22.25 newtons
