Flight Log for 8 July 2000, Boeing Space Center, Kent, WA

Overcast appr. 2500' AGL, wind 2-10 WSW.

Recovery Type Motor Comments
Astron Cobra

12" plastic parasheet
3x Estes A8-5
I had intended to fly this model on B6-6 motors, but when I got to the launch I realized I'd burned most of the ones I'd bought getting the Streamer Duration task completed for NARTrek a few weeks ago, and didn't have three left.  Since this field is on the small side, and the wind was higher than I liked for a high flight, I loaded up a set of A8-5 instead.  Ignition was 3 for 3 again, as usual, and the boost was straight and roll free.  Recovery was fairly close.
Alpha + booster
27
Nose blow tumble
Estes A10-0T/C6-7
This was in the way of sheer fun -- an Alpha on a C6-7 is a high and fast flight; boosting it was an A10 is almost ridiculous, but boost it I did, and though it turned a few degrees on staging (I think this is because of assymetrical venting; one of the booster vents is right over the motor latch), everything else was normal.  Unfortunately, the tip was upwind, and without a parachute or streamer, the rocket didn't drift quite far enough back and landed on pavement just inside the Boeing plant, to be recovered by Bruce Johnson, who's an employee of Boeing.  The pavement impact resulting in cracking one fin fillet, but that can be easily repaired by wicking some CA into the crack.  It'll fly again.
Ninja-B
12
18" crepe paper streamer
Estes 1/2A3-4T
There was some talk about altitude and small motors -- so I figured it was time to remind the gathered group how high you could go on an ordinary Estes 1/2A motor.  The Ninja coasts like nobody's business with the boattail on it, so I sent it up.  As always, it coasted out every bit of the 4 second delay and ejected just at apogee.
BBBertha!

12" plastic parasheet
Estes D12-5
As always, I wished for a D12-7, but with only D12-5 available, I made do with what I had.  I didn't see this, but I was told that the rocket was starting to arc over at apogee when it ejected -- still rising, but definitely turning.  That's about what I'd expect, given that two seconds short of turnover is only about 50 feet below apogee, and the angle should be visible by then.  In any case, recovery, while a way downwind, was nominal, and there was no damage.
Cherokee-D (2)
21
12" plastic parasheet w/ spill and vents
Quest C6-5
Not wanting to repeat the stripped parachute from last week, I loaded up the C6-5 and sent the Cherokee on another journey.  Boost was straight, coast was smooth, and ejection was right on top, with recovery a hundred feet downwind.  With that, I called it a day.
