CT Tripoli # 26 Hurley, NY Saturday launch. LOC MAGNUM on a I300 motor. Dual Deployment tested functional, Main fired at .6 seconds after MAIN due to not reaching over 750 feet. Altimeter sensed altitude was under selected main chute deployment and in .6 seconds the main also popped out. Safe recovery and thrust was 5:1 . First time flying on a I usually fly this bird on J and K695 AMW SKIDMARKS! Just had the motor sitting since last winter, still good! :)
