I flew my Estes Ascender 2-Stage using my homemade altimeter for dual deploy and sustainer ignition duties on Sunday, May 29, 2016, at the National Association of Rocketry's National Sport Launch in Manchester, TN. The booster was powered by an CTI F59-5WT and the sustainer by an Estes F15-P and was ignited electrically via my altimeter. The flight was a complete success.
