I put together t' G78 LMS motor and removed 4 seconds from t' delay, leavin' 6 seconds. Avast! I also used an Aeropack 29-38 adapter.. This worked out pretty well as ejection occurred close t' apogee. Arrr! I had a chute release set t' open t' parachute at 300'. Weighin' 2lb 6 oz, it dropped like a rock and caused quite a jolt t' t' rocket when t' parachute opened. T' shock cord broke out about a 2" section from t' shoulder o' t' 3D printed nose cone.
T' biggest is though be t' cap o' t' retainer was missin' along with me Aeropack adapter when I recovered t' rocket. I can only surmise I didn't get t' retainer cap tightened. Arrr! Blimey! Fortunately, it did push out t' chute.
