Spool Rocket Build Part 1 Parts

In all the years I've been flying rockets, I've never built a true spool rocket.

The closest I've came was my entry in the Rocket Reviews 2009 Two Stage Challenge competition.

I made a two stage odd-ball combining a Squirrel Works Pie In The Sky and a Badminton Birdie.
The Birdie was painted black.
I called it Blackbird Baked In A Pie.
It was a successful, stable two stager, a B6-0 booster to a A10-3t sustainer.


This spool model is closer to the truth.
The parts are simple, you probably have them in your spare parts box.

Grab a couple of old CDs that you never play anymore and send them up.



2 CDs (the picture shows two clear CD spacers, usually on the top of a CD package. I ended up using blank silver recordable CDs)
1 ST-7, 3" long (you could use BT-20 tubing, the ST-7 tube is a little stronger)
2 CR-710 Centering rings (Or, 2050 rings for an Estes BT-20 engine tube)
1 Engine Hook 2 3/4" long
1 TR-7 thrust ring (Or Estes EB-20 if using the BT-20 tube.)
The Launch Lug was pulled for the build, but after starting, it wasn't needed.

That's it!
You will need some epoxy, white glue and electrical tape for this build.
1/4" lengths of a used 24mm casing could be used in place of the centering rings.
The thrust ring could be a 1/4" length from a used 18mm casing.
Cut the engine casings with a razor saw.

This is the perfect small field flyer. I've flown it a few times in the soccer field with a C6-3.
The boost is funny and certainly high enough. Recovery is a very fast spin.
