Jim and I met Bob out at the site. We decided to use my pad and controller and got busy prepping rockets.
I decided to send up my Space Racer on an
A8-3. It lifted off, flew a nice
straight boost, and landed about twelve feet from the pad. The wind
gods smiled... we would have smooth flying.
Bob sent up his Corkscrew on a B8-5. It
spiraled straight up and ejected exactly at apogee... and then the
wind gods decided to have some fun. It drifted over towards the
fenced area behind us and landed on the roof over the swimming pool.
The crack recovery crew (Jim) sprang into action while Bob and I
prepped more rockets. The Galileo Probe
gave a weird flight on a 1/2 A6-2. It
seemed to go unstable at burnout, then the motor fired out... Sir
Isaac Newton predicted the result: the rocket got propelled a long way
in the opposite direction. Bob and I searched for several minutes
before Bob finally found it. In the meantime, Jim had managed to
recover the Corkscrew from the roof by snagging it with a stick.
We were now
ready to tweak the gods...
Bob set up his reborn (see its previous launch) Phoenix with an Aerotech composite motor (E30-4): a first for our crew... Bob set the launch angle to compensate for a light wind. The rocket roared off towards the south with Jim in hot pursuit. It came down over 100 yards from the pad, so he had quite a run... A little kid beat him to it, picked it up and started to run towards his pals, only to fall on it. This gave Jim the chance to catch up and recover the long-suffering model. The motor mount had broken loose in the rocket due to the higher thrust of the E motor, so we were kinduv lucky that it flew successfully...
The Nike Ajax lifted off beautifully on a B6-4. I caught
it just before it hit the ground no more than 30 feet from the pad: a
nice maiden flight. By this time we had accumulated an audience:
"guests" of the school for "troubled" kids, or something like that.
They were inside the fenced area and were quite intrigued by our
activities. They asked us why we were doing this. Our
answer: FUN! I think they could relate to that.
By now the high clouds that were towards the south began to cover the sun. I hadn't flown my Astrocams in a while, so in spite of the conditions I shot up the Astrocam on a Delta II with a C6-7. It yielded a pretty much undecipherable shot. Then I shot the Rastrocam on the Delta II with a B6-4 that yielded another nodescript result. Each time I caught the camera and Jim snagged the booster. We showed the camera to the kids and tried to describe it to them. I'm not sure if they grasped the concept, but they liked the parachute.
Next, Bob fired up his Heliocopter with
a C6-5 motor. It boosted nicely and came down on the other side of
the marshy area. Bob and Jim ran after the copter and booster while I
and prepped the Rastrocam for another flight. As they were returning,
a fellow from the school came up (the kids recess time was over by now
and they were inside) and asked if we saw any of the boys run by.
Apparently one of the "guests" decided to check out without telling
anyone... we saw nothing, but were amused by it. I wonder if he used
the parachute I gave him to help his escape?
The shadows were becoming indistinct, but I shot up the Rastrocam on
the Maniac with a D12-5. It shot
straight up, clicked off the third disappointing shot of the day, and landed
not too far from the pad. Jim and I again snagged the rocket and
camera just before they hit the ground. Bob sent his Black Brant II up on a D12-7
motor. It got some major altitude and took forever to come
down: Bob had put the kit's eighteen inch parachute on it... we waited
while the skies grew cold... then Jim made a fantastic catch even
though the wind gods tried to snatch it away from him at the last
minute.
I had tried to fly my Juno II (made from
the plans in Peter Alway's most excellent The Art of Scale Model
Rocketry, available from Saturn Press)
the last time, but I had forgotten
to install a shock cord in it... So it got its maiden flight on a B6-4 motor. Jim made
the catch about fifty feet from the pad. Nice design, Peter!
I now think the HL-20 got its last flight on a B6-2 motor... It
squirreled up and kind of fluttered to the ground. I've only gotten
one decent 'glide' out of that model so I think I'll retire it and fly
something else next time... I hadn't finished my saucers from AstronMike in
time to fly, but they're ready for the next time.
I had finished my Boyce Aerospace Mercury Redstone in time, though and sent it
aloft on an A10-3T motor. (Since I launched it, there is no photo of
its flight... sorry) The parachute stayed in the body tube and the
rocket thumped down but survived with minor damage to the escape
tower. But then I expected that part of the model to take a
beating...
Bob shot up his Corkscrew again on a
C6-5. Jim was disappointed in the rocket's
spiral: he thought it was too tight. I was gonna send up my Boyce
Aerospace Saturn 1B, but the launch lug
broke off... the epoxy didn't stick to the slick plastic of the clear
lug. Oh well... I've since replaced it with a standard paper lug so
it, too, will fly Next Time. So we skipped the 1B and went straight
to the Boyce Aerospace Saturn V. It flew nicely on an A10-3T motor, but the
chute stuck in the tube as the rocket plummeted to the earth.
Fortunately, it landed in next to the marshy area in some long grass
and survived with no damage. I think I'll use a streamer in it and
the Mercury Redstone if I fly them again...
Now it was my turn to try a composite motor. I put an E25-7 motor in
a Maniac and broke my pad changing to a 3/16" rod... I guess that's
the reason Estes discontinued the Power Plex pad: its weak point is
the metal insert for the thumbscrew. So I borrowed Bob's pad and
fired the Maniac skyward. It screamed out of sight and must have
irritated the wind gods... I finally saw it coming down on its chute:
it was headed towards the street. Once again Jim gave chase as I
hoped it wouldn't land in the street. It looked to Bob and me that it
landed on the median between the northbound and southbound lanes, but
Jim had a much better view: It landed about thirty feet in front of a
car in the northbound lane... the car managed to straddle it without
hitting it. So the wind gods got their little chuckle without being
too malicious.
The honor of the last flight of the day
was given to my Silver Comet on a D12-3
motor. It rose beautifully, slowly rolling on ascent. It ejected
safely and Jim made a spiffy catch to
conclude a wonderful day of flying. And to top it off, I got home in
plenty of time to make a boatload of enchiladas for dinner. They wuz
mighty tasty, too (as was the posole).
