This project started out pretty simple, and just sort of fell together. I
had some left over parts from some other projects, and they just looked like
they should be wed. The name came from the original concept..build something
small, light, and cheap..to try out an Estes E engine for the first time.
I didn't really expect to see it again...
Parts List
Construction
The parts seemed to just fall together, I had a basic idea of what I wanted,
and I was very pleased with the outcome.
The 1/4" launch lug may seem a bit much, but it fit in with the look very
well, and with a strip of 3/4"x1/2" balsa 6"long,added some
needed weight to the top of the airframe. Basically, the two BT-20 were glued
to the BT-50, offset from the rear by 1/4", and on a flat surface, so that
they all attach to the "wing". The "tail" was mounted flush
with the rear of the roc, and 4 fins were added between the BT-20, and the
BT-50, two on the top, two on the bottom. The left-over Heatseeker fins would
be easy to mimic in balsa, but I decided to use what was available. They were
mounted flush with the rear of the BT-20. 21 grams of lead was added to the
balsa nose cone, to move the CG far enough forward to make it stable on an E
and 2 C's.
The shock cord mount was LOC style, using nylon string, and tape/epoxy. A
typical Estes shock cord, and 18" plastic 'chute finished it off.

Flight Report
Oct 23/2001
A beautiful day, NO wind to speak of...great day to lose a rocket! One Shot
Deal flew for it's maiden voyage on a D12-5, to an estimated 925 feet..it sure
looked high! Ejection occurred just after apogee, the rocket landed 150 feet
from the pad, unscathed, except for some heat damage to the paint (minimum
diameter rocket..)
I didn't want to fly it again that day, for fear of losing it, and not getting any video to share, but one of my buddies is worse than a 4 year old, and he bugged and bugged..fine up it goes! Second Flight was on an E9-6, to an estimated 1868 feet! I thought it was gone! Great flight, much straighter than on the D, and Out Of Sight! Thank god for the tracking smoke! Who knows when ejection occurred.. I couldn't see it! Again, recovery was without damage, although it did visit a tree briefly. Next flight should be a cluster, and E9 and 2 C's..maybe then I can say goodbye!

Not as nice a day as yesterday, but I was determined to get some launch photos,
and a video. Wind was about 20 Kph, so I swapped the chute out for a smaller
nylon one, and decided to fly on a D12, rather than an E9. Last DesCon, one of
my entries suffered a CATO, this entry is following that lead. Ignition looked
fine, but before it could even get off the pad..BOOM Hopefully, I will
get it off the ground again.
What is it with these D engines? DesCon CATO (AGAIN!)
As you can see from the flight report, the third flight ended dramatically. I wanted to get some decent pictures for this contest, but I got these... I hope it flys again soon!
I still want to try it on a cluster of an E9 and 2 C6's..
