Brief:
This is my entry into the Design this spaceship contest. I did the Streamliner, and the rocket itself looks great, it is just my mediocre paint skills that did this rocket injustice.

Parts list:

  • 1 BT 60 9in tube
  • 1 Plastic Big Bertha Style NC.
  • 1 Cygnus rocketry 18 to 60 motor mount
  • 1/8 balsa stock
  • 3/16 launch lug,( 1/8 would be better.)
  • Recovery of your choice: 12in chute or a streamer.

Construction:

This rocket is pretty much built like a tank. The fins I covered with paper, Fillets are strong, and a kevlar® recovery line.

I made my own fin pattern by hand and then the rest of the build went on like almost any other rocket.


Fins

Finishing:

I did a primer, then a base coat of Walmart sliver.

Next I hand painted on all the little details that make this rocket a beauty. Unfortuneatly my painting skills aren't to great and I didn't have time or the resources to make decals.

On PadFlight and Recovery:

The first two flights were on B6-4s This is the perfect motor for this rocket. It easily gets 1,000 ft or so and comes down nicely on a 12in chute. Not too fast, not too hard.

The first flight I forgot the wadding so I ruined one of my Hartle Engineering Chutes.

Next flight was a long better and came down some 100 feet from the pad, in the rocks! No damage whatsoever.

Last flight was on a C6-5, What a beautiful launch. Straight boost to 1,200 feet, and then came down sideways on the 1/2 in streamer I put in it.

Once again, not a scratch. Sorry, camera's battery went out and I only caught the smoke off the pad.

Summary:

All in all, this rocket was quick and easy to build and is a true flyer. I have decided to name it the UPFE Steamliner class, OL' DEPENDABLE. For a rocket that will fly through the astroids of space, and come out unscathed. ;).

Wind Notes
12-13-2007 Jonah Dahncke Est SU B6-4 Just Before 5-10 mph winds - Perfect flight. The parachute was melted though but it came down alright.
12-13-2007 Jonah Dahncke Est SU B6-4 Apogee - Perfect 5-10 mph winds - Flight was same as the first, but this time chute opened and came down in a bed of rocks. Not a scratch.
12-13-2007 Jonah Dahncke Est SU C6-5 Apogee - Perfect 5-10 mph winds - Awesome flight. Was gone in a flash and ejected perfectly. Came down on a 1/2 in streamer without any damage.
12-27-2007 Jonah Dahncke Est SU C6-5 Just Past (1-2sec) 0-5 mph winds - Great Flight. NoseCone was blown off and landed sepearatly. Retied and launched again that day.
12-27-2007 Jonah Dahncke Est SU C6-5 Just Past (1-2sec) 0-5 mph winds - 5th flight and I was worried. Rocket landed on the other side of the highway on the train tracks. Upper Body tube is a little crimped but it can be fixed.
