First test flight of the payload section of my BALLS 21 98mm minimum diameter rocket "DDT" The this test flight took place at the METRA field during NERRF 8. The test successfully demonstrated the operation of the recovery system, which was a single-aiframe, dual-deployment configuration. The rocket reached approximatley 3900ft and was recovered about 500yds away. The motor used for this flight was an AT K550 (not a K1100 as it says in the video).
