I am thinking about a 2-3 inch hex tube with a BT-50 center. Hard part will be tapering it down to the nose. So all the ejection pressure will just push out a chute.

Holy resurrected thread, Batman! While I'd still love to see some hexagonal tubes, Rick's square tubing makes for a neat look.

Would look better with PROPERLY SHAPED ROUND tubes.

Welcome back, EV. It's been a while. I think that design
LOOKS GREAT!

I hear that Rick is overcoming his health issues. I see he even released a new design:

Hopefully there'll be many more in the upcoming months.

LOVE THOSE NEW WAY ROCKETS!

Made a cardstock version to look at. No fins but a good idea of overall shape.

Give the tube a layer of fiberglass and it will retain its shape.
