February 2008 launch report (2/25/2008)
On Saturday, February 23rd, MASA held its second launch of
2008. Like last month, this one was held at Sunrise Park
Middle School in White Bear Lake. The weather cooperated, and
we had bright sunshine and blue skies over the snow-covered field.
Temperatures were in the 20's and the breeze was light and variable
out of the south. Recovery walks were generally short, but one
very high flying rocket did drift off of the field to the north.
We had a good turnout for the launch with several visitors and
people flying with MASA for the first time. Greetings to
Michael Cardozo and Sam Tratechaud. We hope that you'll join
Over about 3 hours, 68 flights took to the skies. Being
winter, there were a few "wadded chute" recoveries when they refused
to unfold in the cold, but the snow helped cushion the landings.
Ken Jarosch took the high total of the day with 13 flights.
Ken also burned the only AP of the day with an E11 in his "Stars &
Stripes" flying saucer. Stuart Lenz flew a couple of clustered
motor flights. Caroline Andrews and McKenna Taylor flew two
drag races - first with Fat Boys and then with Quest Aries (built at

Another mild day for some rocket fun. There were quite a
few launches with full racks and even some waiting. I got
in 13 flights with 12 rockets of different types.
I flew the "classic" Fat Boy, the MN. Mosquito - 5x
upscale (Fat Boy based)and the Blue Ninja all on C11-3's.
Next I put up two Patriots from the 90's. A Mini-Patriot
with a 12" thin film plastic chute on a A3-4T and the original
Patriot on a C11-3. The light mini almost made it out of the
Reaching back into my old box, I flew two of my many
Pencil Rockets. I have about 2 dozen with various nose cones,
body weights, fin styles and materials. Rocket "C" used a 4"x
40" tracing paper streamer on a 1/2A3-4T and put in a good
flight. Rocket "A", also on a 1/2A3-4T, had a different nose
cone and a thin mill 1/2" chute which failed to open. Both used
1/16" balsa fins with a long trapezoidal shape.
A scratch built Tornado on a A8-3 did the helicopter
recovery. I followed that with the first flight of the 3X
upscale Tornado on a C11-3. I was pleased to see it work better
than I had hoped.
Still burning up my C11-3's I launched the Stars &
Stripes saucer for rather unremarkable flight. Not enough power
and incorrect balance for the Air Brake recovery. Since I have
E11-3J's to use up I did the Saucer again for a 300'+ flight and
the usual float recovery.
Again reaching into the old box, I pulled out the Lil'
Augie (an Estes Experimenter's Box design) rocket from the
90's with an old motor still taped in it. The C6-7 took off the
pad quickly only to CATO out both ends of the casing blowing the
rocket in 2 places. It was a loud report that got the attention
of the viewers. First CATO in a long time. Not much left to LiL'
Augie. Not to stop there before we shut the range down I tried
the Hi-Flier mod. with 1/64" plywood fins. This is rather heavy
small rocket with a heavy 5" x 50" condenser paper streamer.
This rocket made a good altitude when the large streamer opened.
These streamers are always great. The rocket just floated for
the longest time and when it caught the wind at a lower altitude
it drifted several blocks out side the field.
Burned some motors and watched a lot of flights.

What a glorious day to fly rockets in the middle of
winter in Minnesota! (I may have gotten a touch of sunburn on my
cheeks and nose, I've got that crinkly/scrunchy feeling when I
squint my eyes.)
Well, Phil and I got 13 flights with 8 rockets into the
air and came back home virtually unscathed. Phil's Venture
separated on it's second flight of the day, that's the only
repair from the day's launching.
Here's the rundown for Phil:
Patriot on a B6-4
Sith Infiltrator on a C6-3
Venture on a B6-4
Venture on a B6-4 (separated chute)
Patriot on a C6-5 (took 4 tries before it finally launched)
Cosmic Cobra on a C11-3 (should have used a 5 second delay)
Custom Freedom on an A8-3 (chute not fully deployed)
Estes Rascal on a C6-5
Gemini DC on a C6-5 (only one chute opened fully)
My Blue 4FNC on a C6-5
Cosmic Cobra on a D12-7
Rascal on a B6-4
Rascal on an Estes B4-4
We left shortly after noon leaving a whole slew of
people still launching rockets.
There were a few prangs including a double fence-post. I
think that was Glenn's but I'm not sure as I was prepping a
rocket when it launched and only saw the two darts from the
separation come in. Mark had his own version of BOINK because of
a spit motor and somebody else's maiden voyage came in hard with
much carnage. Alan or others will verify for prang of the year
awards at the Christmas party in December.
