I've got a couple of mini-cd's that I'd like to use for spool rockets, but I'm not sure they'll work. They are the kind that look like they've been squared off on opposite sides, so it's more like a square with 2 bulged sides.

Will these things fly as a CD-Spool? I'm thinking a 13mm MMT would do nicely for these little things.

What would happen if I offset the cut edges by 90degrees, so instead of being lined up, the squared sides on one are lined up with the curved sides on the other.

Anybody ever try this?

Lance, are you out there?

You lookin' for me?!? hehe

I would think that you'd get the best performance with the CDs aligned together... A few months ago I built a "spool" with 2 pieces of square foamboard as the discs. Had it lined up to look like a sideways TIE Fighter. Flew about as well I expected it to.

And do yourself a favor: put an 18mm MMT in there. Before mine suffered from a pair of fatal cracks in the discs, the spool with the mini-CDs was far & away my best CD spool rocket I ever built. Less plastic means less likely to break & more rigid. Expect ~300-400ft with a C6-5 and lands as close as any other CD spool rocket. Impressive I tell ya!

Please post any updates to your project! :D
