Now That's What I Call a SPOOL!

Room for a 98mm.
Actually, the tube will be cut down to about 1/2 of that length.
Gonna stick 7 38mm tubes in it just because and because 7 38mm tubes all butted up agin one another fits perfectly in the main tube.
Thinking recovery via "Duck and Cover!!!"
No, not really.
Parachute of some sort.

Might be worth ducking even with a 'chute. You gotta plan for visual documentation of the flight!

How are you planning to reinforce the plate/tube joints? Under 98mm power they'll be experiencing a lot more force than typical rocket components.

I really should make myself a spool.

VISUAL DOCUMENTATION!!!
Are you kidding?
I may not be the brightest, but I ain't stupid.
I'm not being anywhere near out in the open for that.
I'm planning on "watching" from a culvert.

It isn't going to have a 98, only room for one.

One isn't enough?

(at least when it's a 98...)

Yea, but you think you can't shred it with 7 J's

I1299's!



(Now that would make for an interesting flight...)

See the "culvert" comment above.
It's all for fun.

Did someone say spool?!?

Anyhoo, my advice for launching large spools is to send them up from the furthest pad(s) that your club has. Check out my homepage (link in my sig). A fellow club member built a spool to fly on an I157. While NAR/TRA safety code says 100', we sent it up from the 200' pad. It safely stayed away from the flight line, which is all you could ask for.

If you haven't heard me say it before, the ideal length to diameter ratio for spools is 1:1 (motor tube is same length as the disc diameter). 1.5:1 is my recommended max to guarantee stability. Anything greater than 1.5:1 puts you in a position of questionable stability & greatly reduces the rocket's already low altitude.

HTH & good luck!
