The motor that was chosen for this launch was a DMS I280 from Aerotech. This was because it closely mimicked the speed off the rod and average thrust of our predicted final rocket motor. The I280 that was purchased included Magnesium in its propellant to create the sparkling flame trail behind the rocket. | The motor that was chosen for this launch was a DMS I280 from Aerotech.
