Flight Date: 2014-01-18
Rocket Name: 1.77x Upscale Duster "Dubya"
Flyer's Name: Matthew Bond
Motors: H165-9
Expected Altitude: 2,114.00 Feet
Wind Speed: 5.00 mph
Launch Site: SEARS
Actual Altitude: 1,919.00 Feet

Another great flight.  Swapped out the delay element to get a 9 second delay.  Nice boost, quick and straight, leaning a bit into the wind.  Arcing over at the top of the climb, pretty much at apogee for ejection.  Good chute, not much drift up high but moving a little closer to the ground.  Landed in the field on the far side of the creek in a prety wet area.  No damage and no real water soak up either.  Remembered to get the Altimeter Two onboard and powered up: Max altitude 1919 feet, max velocity 331 MPH, burn time 1.1 sec, peak acceleration 19.8 g, average acceleration 13.5 g, coast time to apogee 6.8 sec, Ejection at 0.3 sec before apogee at an altitude of 1872 feet, descent rate 1.7 MPH, total flight duration 77.4 seconds.  About 2000 feet short of the RocSim predicted altitude, I may have to go and tweak the drag coefficient some.
