06/08/1975Mike Colby Dad’s BackyardC6-3The maiden flight was very good. Very little wobble was detected. Recovery was good. It was unwise to use such a powerful motor, but the guys wanted to see it so it was launched with a C6-3. Recovery was between the house and a few trees. The drift showed the various wind directions in the upper atmosphere. At one time the rocket would drift slow and the next fast. It changed directions several times too. Rocket was recovered with no damage
06/08/1975Mike Colby Dad’s BackyardC6-3This launch occurred twenty minutes after the maiden flight and was a good one. On this flight the shock cord pulled loose from the main body tube leaving the rocket fall freely. Despite the free fall, it landed in almost the same spot as the previous flight. Except for the shock cord incident the rocket was recovered with no damage.
