Launched at the monthly TTRA launch in the Varn ranch in Plant City FL. "Airstart 1" is a scratch-built two stage rocket that has a 2.5" dia. upper stage and 3" dia. booster stage. The upper stage's fin/motor section rests in the four 6" deep slots in the top of the Blue Tube booster section. Aerotech I200-10 booster motor and H250 upper stage motor. Perfectflite timer for staging and a Perfectflite altimeter for drogue and main chutes deployments. Parachutes by Phylachutes. Aiptek Hi Speed HD camcorder which shoots video at 60 fps. Rocket achieved an altitude of 2668 feet on a very windy day. Booster section landed safely by parachute next to the spectators. Drogue chute shock cord on the upper stage became tangled at deployment, accounting for the dizzying video and upside-down video after main chute deployment at 400 feet. I'm going to try a deployment bag for the drogue chute at next launch.
