== Quick G Calculation ==
Quick way to calculate g’s on liftoff:
Take the average thrust of motor in N, divide by 5 to get lbs, divide by the weight of your rocket, you want to aim for around 5 - 6 g’s.
The H550 motor puts us at an initial launch acceleration of 30g’s, approximately 90 ft/s off the launch rod, so anything inside the tube will shake uncontrollably and possibly break. It will also cause the parachutes and other stuff in the rocket to be shoved down the tube. Be careful about how you attach the coupler as screws can catch the parachute and make it fail. Ask Ian on how to explain this to the safety officer!
