Launched at the monthly TTRA launch at the Varn ranch, Plant City, FL. CINEMA 4 was powered by an Aerotech I200 motor and carried an Aiptek camcorder. The shock from the drogue deployment dislodged the battery from the altimeter, and the main chute never deployed. The landing was hard, but fortunately there was no damage to the rocket. I'll tape the battery in place next time!
