I came home from my trip to find the grass had grown quite a bit. Perfect opportunity to test the main parachute charge on the Polecat Black Brant III before mowing the lawn. 1.3G of 4F black power was used and once again I used vacuum on the RRC3 primary altimeter to test the charge. This was the last step in preparing the rocket for its first flight, and my L2 attempt using an Aerotech J270W motor.
