Excellent day! The only negative was the waist deep grass adjacent to the main field. Several went in, all came out. At least mine did.


My Flights:
  1. Estes Der V3 on a D12-5 - Old rocket - still flies great. Chute Release @200'.
  2. SpaceShipSQRT(-1) on a C11-3
  3. Zoomie P51D on a C11-3 - This got the most comments of all my rockets today.
  4. Big Dipper Daddy on an E12-6 - Chute Release @300'.
  5. Shrox Industria SHX-15 on a C11-3 - Swooped around on the way up, as always.
  6. X-20 Dyna-Soar Carrier on a C11-3 - See comment below. 
  7. MLAS-S on an F15-6 - Great flight, Chute Release @300'.
  8. Odd'l Wedgie on a C6-3 - As experience and the designer dictates, I used an Ested C6 v. the Quest variety. Corkscrewed badly probably due to me not seating the motor mount correctly. A kid really loved it so I gave it away.
  9. Estes Mini Marz Lander on an A10-3 
  10. Half ASStron on a C6-3 - Aparently, this is now flying at every NARHAMS launch.
The X-20 Dyna-Soar Carrier is a shortened version on The Days of Future Passed.  That rocket always looked too long to me so I modified the Rsim file. To my delight, I found it was stable. I'm not exactly sure why I stretched it. I did like the harness that brought the DinoSoar section down parallel to the ground but too long is too long. So, so long upper body tube. I will save it just in case I change my mind. I also retrofitted 1/4" lugs as the sims showed is needed a 4" rod to fly on C11s or D12s.

Amateur 3D-printed rocket motor flew at FAR

Last Saturday, UCSD's Students for the Exploration and Development of Space (UCSD SEDS) became the first university organization to launch a 3D printed motor. Pretty amazing!

A blast from the past heads to the dump

Prompted by the unrelated relocation of stuff in the Dungeon, I decided that I need to thin the herd. However, when contemplating what should go and how, I find it's going to be very difficult. I started with 'the boneyard, a corner where I pile damaged and generally unflyable rockets. I manged to come up with a mere four candidates. I drug these begrudgingly to the trash and took photos to remember them by. Only three made it into the can and the fourth will make its way back to the boneyard. Like I said, very difficult.

One of those being chunked is the carcass of the CrayShipOne. This rocket was built in 2005 for EMRR's NASRoc and MonsterRoc photo contest. This was a crayon rocket celebration of the SpaceShipOne and features NASCAR-like sponsor stickers. It won 1st place and snagged me a copy of the "Spaceship Handbook" by Jack Hagerty and Jon C. Rogers.

On its last flight, the 'chute snagged and broke the main wings/fins. It has sat idle for a couple of years and, thus, had to go.


In memoriam, here's the text from my entry:

YEEEEE HAW! CrayShipOne is 4" x 47" of AP-burnin', heads-up callin', crowd-pleasin' craziness. Weighing in at bit over 5 pounds, it is bound to make any RSO sweat bullets! A Loki H144 should boost this MonsterROC to around 1000 feet.

CrayShipOne sports logos from a D.C. rock station and MDRA, and has custom stickers for all its major "sponsors". If you want to see your logo proudly displayed on the CrayShipOne, you had better hurry - there may not be a second chance! After it brings home the MonsterROC Prize, the builder hopes to market the design to a British (make that ANY) billionaire.
