Mark Howe April Launch report
April 14, 2008
SPARC held its' first launch of the 2008 flying season on Sunday, 04/13. I arrived about 9:15...a little late due to the "fried chicken" not being ready at the local Albertsons's market when I got there, which caused a 15min delay in my travels. There were already half-a-dozen cars at the field and the club trailer when I arrived. After greeting old friends who had not been seen during the looong coooold winter months, we got the range set up and activated the waiver around 10AM.
I brought 14 rockets to fly, but only managed to get 10 up in the air.
Most of the flights were first time flights of kits I built over the
winter. Here's a quick recap:
* Estes "Der Red Max". First time flight. Motor = C6-7. I would
definitely consider downsizing the parachute from 18" to a 14" or even
12" chute.
* Estes "Guardian". First time flight. Motor = B6-4. Nothing
spectacular to report...just a good standard flight profile.
* Estes "Pop Fly". First time flight. Motor = B4-2. This unique
rocket looks like a miniature baseball bat, with a ball attached to the
top. The bat portion recovers using a chute, and the ball tumbles down.
You're supposed to try and catch the ball...hence the name. I decided
that attempting to catch the ball was not really conducive in a
multi-pad range set-up...too many obstacles and wires in the way. I'm
thinking of purchasing a full size wiffle-ball bat and "upscale" this
kit for 24mm power.
* Estes "Screaming Eagle". First time flight. Motor = C6-5. A
replica of an F15 fighter jet which recovers on a chute. It turned in a
nice flight.
* Edmonds "Stage-2 Thunder". 2nd Flight. Motors = D12-0 & D12-3.
I really enjoy gliders and helicopter recovery rockets. Edmonds makes
the best gliders in my opinion, and I have practically all of his models
in my fleet. The Stage-2 Thunder uses 12" gap-staging...very unique!
The top stage didn't eject the motor fully which messed up the
weight/trim a bit. It still flew great and I had the added bonus of a
shorter recovery jaunt than if the motor has ejected properly. I still
had to walk about 150 yards to recover the top stage, which took off due
west in a straight line. Thanks to Terry for recovering the bottom
stage glider for me.
* Scratch built "Marvin (the Grateful Dead) Martian". First time
flight. Motor = D12-3. My homage to "Marvin the Martian" of Looney
Tunes fame. I painted the rocket to look like Marvins' uniform, and
added a number of decals picturing him (along with some Grateful Dead
decals...they produced an album called "From the Mars Hotel" so I
thought it would be appropriate). It turned in a good flight, but the
2.6" diameter and long length airframe really needs a bit more power
("E" or "F").
* Estes "Rock-It". First time flight. Motor = D12-3. The
"Flintstones" rocket. Looks like it's made from stone with a "chiseled"
nose cone and painted with stone textured paint. Two of these models
were at the range today, and both exhibited a fair amount of spin on the
upward trajectory.
* Estes "Rubicon". First time flight. Motor = D12-3. Based on
one of the "X-Prize" contestants, it's a multi-tube / multi-colored
contraption that was a pain to paint. The chute fouled on deployment,
and the resulting landing was a bit harsh...I need to re-attach 4 of the
six fins a one fake engine nozzle.
* Estes "36 D-Squared". First time flight. Motors = D12-5
(Qty=2). A 2-engine cluster, I stretched my version another 8" to make
it 44". It turned in a great flight.
* Rogue AeroSpace "Space Needle" 5th flight. Motor = 24mm RMS
E18-7W. Should have called it quits before this one...the faulty
copperhead igniter during its' first launch attempt should have been an
omen to me of things to come! This rocket is skinnier than a mean
machine, and 50% taller (9-feet). The wind picked up and rocket was
leaning...but I pressed the launch button anyway. Instead of
weathercocking into the wind it went horizontal, managed to do a flip
(really not sure how that happened) and crashed to the earth. One
broken fin and a couple of spiral separations on two of the body
tubes...a major rebuild will be required.
I assumed LCO duties for most of the day...it's something I really enjoy
and was still able to get a fair number of birds into the air.
Unfortunately, I was LCO when Jeff Halstead's shakedown flight went
roaring into the air. I can't believe I made such a rookie mistake and
had the wrong pad group selected. My apologies, Jeff!
The turnout of fliers was much higher than I anticipated. Thanks to
Dave Luders for bringing a bunch of teens, I think they were part of a
scout or explorers group. At one point we had three rows of cars behind
the flight line, I was impressed. One of our newest members, Peter
Hoff, showed up with some nice detailed kits in the model thru high
power range. Lou Bragg had a few nice high power flights, as did Bryan
Schopp, who also dabbled in mid and low power. Thanks to Katie for
managing the waiver & wristband functions.
Dave Glass had his "usual assortment of unusual birds", From Mad Maxine
to Normal Norman. Normal Norman put on a great show by air-starting two
D12 motors via FUSE! Joe Cooney had a nice selection of rockets, and I
believe progressed the farthest in the "Alphabet Ladder" race. Joe and
I always give our rockets nicknames based on Grateful Dead
tunes...Deadheads unite, we're everywhere!
Marty Weiser and his skeeter collection gave everyone eyes a workout as
we tried to follow their trajectories...and later on by searching for
them on the ground...
Last but not least, Terry Moore-Reed and Ray Stoner showed up, but only
as spectators... :-(
Lots of new faces...great weather...PLENTY of rockets launched (who has
the completed flight cards????)...hope we have more of the same at the
next SPARC launch, which is a 2-day event scheduled for May 10th &
11th!!!
Thanks!
Best regards,
Mark W. Howe
