Rail exit velocity Launch guide length: 96.0000 In. Velocity at launch guide departure:
60.3 ft/s
Parachute sizes and descent rates The drogue parachute parachute was
built by Ernie Puckett and descent rate is 88 ft/s.
The hemispherical main parachute was donated by Edward Warinski of Alpha Hybrids.
Velocity at landing: Vertical: 17 ft/s. 54inches in diameter with 8 inch spill
hole.
Test plans and procedures The first flight of our scale model occurred
January 17, 2009. The full scale rocket was flown on March 14,
2009 Video footage from March 28:

Dual deploymentavionics test We successfully tested the avionics
in both rockets and we are using the same equipment in the full sized rocket with an added G-Wiz flight computer back up system.
Ejection chargeamount test
We used .75 grams of black powder in the scaled down rocket. We calculated this using the uroc.org black powder calculation website: http://uroc.org/index.php?option=com_wrapper&Itemid=628
We used 1.4 grams of black powder for the drogue parachute and 1.7 grams of black powder for the main parachute. We used the black powder calculator on: http://www.info-central.org/recovery_powder.shtml
Payload integration feasibility Camera bay hatch. "Record" access hole added to hood. Transmitting GPS donated as a loaner. Small
logging GPS and a sonic locator optional.
