Quest Cobalt Clone Build Part 1 Parts

This may look like a standard build but we will be covering:
  1. Making your own centering rings from card stock and cereal box cardboard
  2. Making a "close" clone from a internet photograph
  3. The Odd'l Rockets XLEH EXtended Length Engine Hooks

I know that most modelers would "clone" a favorite old rocket model that has been out of production (OOP) for many years.

The Cobalt is a new kit. It was first shown in last year's Quest catalog with a scheduled release date of July, 2010. It was released just a few months back.
I have a few extras in this nose cones style (PNC-40) and plenty of the Quest 40mm body tube.
Why not build a new Squatty for the A6-4 schoolyard launches?

Please note, this will be a close, not exact clone of the Cobalt.

Parts needed from Quest:
PNC-40 Nose Cone
T403000 40mm Body Tube 4" needed

I supplied other parts from my stash:
1/8" X 1 1/4" Launch Lug
3/32" Balsa
12" Kevlar
18" Round Elastic Shock Cord
2" Wide Crepe Paper Streamer

Specialized Engine Mount
3" Long ST-7 Engine Mount Tube (Semroc)
TR-7 Thrust Ring (Semroc)
One Odd'l Rockets XLEH Extended Length Engine Hook
Two homemade Centering Rings (ST-7 / 40mm)
The rings in the picture are not the ones used in this build.

  1. After supervising the local Civil Air Patrol cadets' rocket building session and helping with some of their demonstration launches, I would recommend "stretching" the body tube 2" to 6" long so there's ACTUALLY ROOM FOR THE STREAMER! =8-O

    Over and over again, the ejection charge consistently melted the plastic streamers into lumpy "stream-wads."

    Lengthening the body tube would also make the rocket more stable. You *might* be able to fly it with a "B" motor, but probably not a "C"... unless you were looking for an extremely memorable flight. (dismayed look)
