February 2004 launch report (3/1/2004)

Hey, it's warmer than last month !

On Saturday, February 28th, a pretty-good-sized group of people (for a winter launch) came out to the field in White Bear Lake for MASA's second launch of the year.  The weather was pretty decent with temperatures in the 30's and a light wind out of the south.  With 79 flights, this was probably the largest number of flights ever at a MASA launch with snow on the ground.

Thanks to Prez. Mike Erpelding for driving all the way down with his truck o' equipment.

A few of the flights:

MASA members - please send in your thoughts about the launch!

A really nice crowd today. In order to promote the open contest and use (or lose) my many 1991-92 high performance rockets I have been saving for such an event, I came prepared to fly 1/2 A to D streamer and parachute duration.

But because of the winds , I quickly decided to keep the power down to 1/2A mini and A regular rockets. I also removed all the thin film parachutes and replaced them with my only unused streamer, a dual 2" x 20" plastic unit. I had to tightly wrap this to get it into the mini tubes. This mass and old shock cords resulted in deployment failure. The streamer ripped out the shock cords with the nosecones. The B streamer ripped the nose cone away from it's shock cord. Only the A streamer with it's heavier and longer cord survived but the weight blow the motor out past the weak Quest motor hook. A second attempt with the Pip Squeak 2 and a loose nose cone and taped motor finally worked.

All these rockets will be reworked for an external smooth tube mount. I also flew the "in field" junk rockets on a C11-3 with a 12" chute.

I did not get to try any of my yet untried real contest rockets. Maybe later on.

It was a bright and sunny February day with temps in the 30s and winds 10 to 15 MPH. Mike E, Ken J and Alan E were almost finished setting up the equipment when Ellison and I arrived just before 900 am. Alan was first to launch, Stomp first, saucer second. Having missed the January launch, Ellison and I had a difficult time just launching the new rockets, even got some of them painted. I brought my kit bashed Renegade but choose not to launch it with the winds and small field. Streamers (or Boink) were the recovery device of the day and even some of these drifted out of the recovery area. My first rocket was a Flis Long Overdue that ended up on a power line. We also flew my new Black Funnel, Short Ringfin , Acme Spitfire and some older classics Luna 2, SS Casseopiea, and downscaled 1/2 Andromeda. Ken J spent most of the day on streamer duration models. Lee F arrived just as we started launching, Glen O and Ted C arrived later for some nice flights. We also had many new people and families launching with us. We kept 5 pads busy until 1200, packed up and Glen O, Mike E, Ellison and I sent to Arbys for lunch. Lots of wet shoes today.

I had to come late, and had to make up for it by leaving early -(.

There were a lot of people there!

I flew a Tumbleweed/Astron Sprite scale-up for the first time on a B4-2, and my Silver Comet on a C11-3 and a D12-3 on its 38th and 39th flights. Too windy for the Shuttle or the Honest John.

Ellison Lenz made a good start on the prang nominations with an unstable bottle rocket and an unstable mini Bertha. There was a noisy CATO that wiped out a RTF kit and unfortunately upset its young owner, but the rest of the flights I saw were pretty uneventful.
