I successfully completed my L1 certification flight last Saturday. The flight was made at the SMRA site in Alamogordo, NM. The Zephyr flew flawlessly on a Aerotech H283 dms motor. The rocket left the pad so quickly, we only got 1 photo leaving the pad. The wind was higher than I hoped for so I used a Jolly Logic Chute Release. The rocket landed about 50 yards outside the perimeter fence. For anyone thinking about a rocket for L1, I would definitely recommend the Zephyr. The only addition I made was an Aeropack motor retainer.
