I have expressed and continue to express how much I enjoy flying
my Nordic Rocketry Meanie kit. This
kit has now logged 20 flights (as of 7/99) and is my traditional first flight at each
launch.
Well, liking this kit so much I first decided to build a
2x upscale. That venture was fun and very much a learning activity as my
Meanie x2 crashed on it's first flight. I am
nearly finished with the second Meanie x2. In the meantime I slapped together a
Little Meanie (1/2 scale).
I took my Quest
Icarus and turned it into my Little Meanie. This rocket worked very well
since its diameter is 1.378" which is roughly half of the 2.6"
diameter Nordic Meanie. I cut down the body tube so that with the nose cone I
had a length of 12".
I then drew a scale pattern of the Nordic Meanie fins and
took that to a copier and reduced it until the root edge was exactly half the
length of the original. I then made three copies of it and cut them out. Next I
CA soak-glued these templates to some 1/8" balsa wood so that the grain
was parallel with the leading edge. After drying I used a hobby knife and cut
out the fins.
I evened up the edges by holding them all together and
sanding them. I just barely rounded the edges before gluing them onto the body
tube. I followed with fillets made with white glue.
Since I was using the BT from the Icarus, I already had
the motor mount and Kevlar® shockcord in place. I tied a new two foot piece of
1/8" elastic to the Kevlar® and tied the other end to the nose cone. I then
used the Streamer Calculator that is available on the
"Calculator/Tools" page and determined
I needed a 24" x 3" streamer. NOTE: I used plastic construction
warning ribbon that is 3" in diameter.
The final check was to ensure the CG with a "C"
motor was proportional to the CG of my Nordic Meanie with a "F"
motor. It was actually a little more toward the nose and therefore I felt it
would pass for stability.
After all that I painted it to match the color scheme of
my Nordic Meanie and was ready to fly it.
FLIGHT/RECOVERY:
My first flight was on an A8-3. It was fast off the pad
but in sight the entire flight. Ejection was a tad bit early and with the
streamer it was a successful recovery.
The second flight was on a C6-5. We watched this Little
Meanie fly out of sight! Saw the delay smoke as the rocket arced over and then
never saw it again. Three of us were amazed that we never saw it falling. Thus
ended the Little Meanie's flying days.
It is a great scale down and I will plan on doing
another! How many of you have done scale downs?
