Flying my Estes PSII Nike Smoke rocket at Fire In The Sky 2016, Mansfield, WA. Both flights were perfect on Aerotech G64-7W motors, which use the 29/40-120 reloadable case. Jolly Logic Chute Release was used on both flights, minimizing drift in the windy conditions. Love this kit, looks fantastic and has great performance on relatively inexpensive motor loads.
