So I found myself near the end of a great day having flown every rocket I had brought to the field.  Since the weather was still perfect and I still had time to spend I decided to get in one more flight of my upscale Black Shadow.  Loaded up a CTI G68WH and let it rip.  Great boost, straight and fast off the rod.  Arcing over at the top of the climb, still slightly nose up at ejection.  Good chute, minimal drift, landed on the field with no damage.  Perfect way to end a great day.  Flown with a Jolly Logic Altimeter II with the following data recorded: Burn time 1.7 sec, peak acceleration 15.6g, average acceleration 10.2g, coast time to apogee 7.7 sec, ejection 0.1 sec before apogee, ejection altitude 2168 feet, descent rate 14 mph, peak altitude 2292 feet, peak velocity 370 mph.
