18" plastic parasheet |
Estes A3-4T |
This first contest flight for the Boeing Employees' Model Rocket Club
non-sanctioned summer contest series suffered a partial deployment and
still turned up 33 seconds. As with last year, I have trouble getting
the Estes parasheet to fully open from a BT-20 with the very light Ninja
underneath. |

Second contest flight, parachute deployed as a spike but due to the
very high flights from this boattailed coaster, I still turned in 35 seconds;
these two flights were good for first place due to a high proportion of
DQ results from other fliers. |

6"x60" 2 & 1 Z-fold chart paper streamer |
Estes B4-6 |
This was my first contest flight for the B SD contest; it was a straight,
high flight, and deployment was good, but the nose cone and streamer separated
from the body (which recovered without damage) for a DQ. I didn't
realize it until the contest was over, but the problem was that I was attaching
the streamer's leader to the non-elastic carpet thread portion of the shock
cord, rather than at the nose with a couple feet of elastic between streamer
and body; as a result, the momentum of the ejected streamer was breaking
things. Ah well, live and learn. |

Second contest flight, with a new snap-swivel in the shock cord train
(and my second streamer as backup, since the first ripped on deployment).
Same result, near enough; this time the carpet thread external shock cord
snapped at a knot, conclusively demonstrating that knots weaken a line.
Once more, both parts were recovered without damage, but another DQ was
scored. |

18" nylon parasheet |

As always with the Spike on this motor, low and slow, less than 150
feet, with recovery after apogee but with plenty of time for parachute
deployment. Always a good show flight. |

Nominal flight and close recovery despite the breeze. Ignition
with the Tiger Tail II igniters was instant, as usual. |
