Launch Report 2008-10 - if pigs could fly

Location: Central Sod Farm, Centreville, MD (MDRA ESL-123)
Weather: High-80s, wind 0 - 5 mph
Total flights: Today - 12 ; YTD - 109
Total motors: Today - 14 ; YTD - 134

Well, I flew on Sunday instead of Saturday due to a conflict with Fajita Fest. I ran into Don and Richard and got to visit. Don gave me some plastic doohickeys that are suitable for nose cones or cockpits.

There were lots of misfires on the low power pads which got annoying. The low-light, however, was when I was helping Neil push the button so he could photograph some flights. On one round, I thought the 1st rocket was on pad #1. When I pushed the button, I fired Ben's static test, which had borrowed pad #1's leads. D'OH. Even though Ben didn't get any data, he was a good sport. He was happy the EX 'J' worked.

Oh, yeah, pigs did fly :) Well, one pig anyway.

My flights:
  1. Art Applewhite Stealth D5 on a D5 - This was a revised design. It had a slower spin, less arc-over, and not even any discoloration of the case.
  2. Art Applewhite Saber D5 on a D5 - This spun a lot but not as much as the original D5 Stealth. There was a little discoloration of the case, but no burn through.
  3. Art Applewhite Cinco 24mm on a D12 - Nice flight. It seemed as high as the D5 version but it was hard to tell since it didn't fly at the same time (due to a misfire).
  4. Art Applewhite Cinco D5 on a D5 - Nice long burn. Slower than the D12 version.
  5. Art Applewhite Delta Saucer 24mm on a D12 - Drag race with the Delta D5. The boost was faster but lower than the D5 version.
  6. Art Applewhite Delta Saucer D5 on a D5 - Slower but higher than the D12 version. I noted all the D5-powered rockets arced-over near the end of their burn.
  7. Art Applewhite Double Helix 24mm on two E9-4s -Nice flight but it experienced a double burn through. No additional damage though. The spewing of propellant is actually pretty cool.
  8. Heavenly Hobbies Backdraft on an E9-4 and C11-3 - The retro motor was ignited with a 7.25" fuse. You could clearly see the fuse light, which made me feel better. I lost sight near apogee until the retro motor went off at about 400'. It clearly rose a ways before falling for 3 seconds and ejecting the 12" 'chute. Everyone though it was cool. The tube was dinged a little when it landed on the gravel road, the plug that protects the 'chute from the booster ejection was lost, the Kevlar cords all look like they need to be replaced, and the ejection piston is really burning up. It might fly again but it probably won't be soon.
  9. NCR Archer on a G80-7 - This was a cool flight on the new higher impulse G80. Ejection was NC-down. Very nice motor.
  10. Scratch Chasin' Tail on a F45-5 -Folded like an accordion. 'Nuff said :(
  11. Semroc Gee'hod on a C6-3 - Nice boost but the 'chute didn't open. A slight repair to the RPG tube is required.
  12. Semroc V-2 on a B6-4 - Nice flight and recovery.
