Flight Log for 8 May 1999, Boeing Space Center, Kent, WA

Broken clouds app. 2500' AGL; wind 5-15 variable S to SW.  One of the better rocket days so far this year!
Model Flt

Recovery Type Motor Comments
Thug
12
24" nylon parasheet Aerotech RMS 29/40-120 F52-5T The Blue Thunder motor does a fine job of moving this rocket off the pad -- even though there are only 40 Ns of impulse, it flies as if it were more motor because it build up velocity quickly and then coasts longer than the F40.  This flight was picture perfect; if I'd had another F52 handy, I'd likely have reprepped it and flown the Thug again.  Unfortunately, there was too much wind to fly a lower thrust motor in this stubby airframe.
Spike
22
18" nylon parasheet Aerotech RMS 24/40 E18-4 The old standby motor for the Spike, the E18 can always be counted on for a good flight.  Unfortunately, the same can't be said of Copperhead igniters.  After burning a Copperhead, then a Laserfire in the motor, I installed a thicker Copperhead which didn't even burn (probably due to edge shorts) before getting a good one, originally for an H or I motor, that ignited the propellant and created a nominal flight.  By the time I'd pulled and recycled the rocket that many times, it was time to break down for the day and go home.
