Flyin' me Estes PSII Nike Smoke rocket at Fire In T' Sky 2016, Mansfield, WA. Aye aye! Both flights were perfect on Aerotech G64-7W motors, me bucko, which use t' 29/40-120 reloadable case. Begad! Jolly Logic Chute Release was used on both flights, minimizin' drift in t' windy conditions. Love this kit, looks fantastic and has great performance on relatively inexpensive motor loads.
