June 21, 2007 evening launch report (6/29/2007)

On Thursday, June 21, MASA held its fourth launch of the year. This solstice evening launch was held at the VFW soccer fields near Elk River.  Flying started around 4pm and wrapped up around 8:30.  Turnout was very light; some potential fliers stayed home due to the chance of thunderstorms.  The weather was actually very nice.  The thunderstorms stayed away with only a light sprinkle felt at the field.  In grand evening fashion, the breeze died down to complete calm after about 7pm.

A few of the flights:

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

Just to rub it in a bit <grin>, but you all missed a lovely evening for launching rockets. The Shmel family and myself were the only ones to avail ourselves of the VFW fields to fly some rockets last night. It was sprinkling a little when I arrived, but that quickly passed. One dark cloud later gave us a few drops; otherwise, the sun came out, and the weather was very nice. The breeze was out of the east, but, in typical evening fashion, had dropped to essentially calm conditions by 7:30.

I flew the following
"Quest Thing", A8-3 - good flight, one fin broken on landing
"Alpha Thing", A8-3 - good flight
"Der lil Red Max", 1/2A3-2t - good flight, one fin missing on landing
"Galileo", 1/2A3-2t - good flight, two legs popped loose on landing
"Bullpup", B4-4 - good flight
"Tangent", B6-4 - good flight
"Hercules", B6-0; B6-6 - at staging, the booster motor spit out leaving the booster stage attached to the sustainer. The upper stage motor, firing through the booster, turned it into a crispy critter. :-(
"Chain Lightning", D12-5 - good flight, landed in the former horse pasture across the road
"Screaming Yellow Zonker", E9-6 - good flight
"Rings of Fire", C11-3 - good flight
"Super Duper V2", D12-5 - on liftoff, it must have gotten momentarily bound up on the rod because it briefly tried to take the whole pad with it. Needless to say, that negatively impacted flight performance. The rocket came in ballistic and ejected at an altitude of, oh, about 3 feet. Some damage to the front end of the body tube, but nothing that can't be fixed.

We launched 10 flights as follows, (not in any order):

1. Baby Bertha on a B6-3 - Nice flight, the Baby rocks on.
2. Blue Ninja on a C11-5 - Probably should have used a 3 second delay.
3. Bull Pup 12D on B4-6.
4. No. 2 Sky Writer on B6-4 - Bottom of plastic fin can melted. Not  sure if it was rebound from the blast deflector or just radiant heat from motor. Weird.
5. StormCaster on a C6-5 using a 24mm to 18mm adapter.
6. FlisKits A.C.M.E. Spitfire on C11-3 Apogee - The kids in the park enjoyed this one. Not too much altitude - chute didn't open completely - but great flight.
7. Fat Boy [YellowJacket] on a C11-5 - chute was too large. Rocket drifted and landed in parking lot. Minor damage to fins.
8 & 9. X-Flier drag race on B6-4's. Looked like a tie to me.
10. Video BT-56 on a D12-5. Chute separated from video nosecone at ejection - capsule free fell to ground - no damage. Video was good.  Thanks to Alan for finding the camera.
