Nice flight of the Blue Bird Zero upscale.  Swapped the delay element out to get an 8 second delay.  Straight and smooth off the rail, arcing into the wind at the top of the climb.  Still nose up at ejection, good chute, fair amount of drift on the way down.  Mud landing on the field, no damage.  Flow with a Jolly Logic Altimeter II with the following data reported:  Burn Time: 1.3 sec, Peak Acceleration: 14.0g, Average Acceleration: 9.5g, Coast Time to Apogee: 6.7 sec, Ejection 0.6 seconds prior to apogee, Ejection Altitude: 1742, Desent rate: 14 MPH, Flight Duration: 91.5 sec, Peak Altitude: 1811 feet, Peak Velocity: 266 MPH.
