I would assume the body and nose recover separately? If not, I would make it so. Would not want those two large pieces clanging together on the way down.

As to canopy area, do the two pieces way weigh about equal parts? Or, thereabouts? If they are roughly the same weight, then basically a pound under each 30” canopy (or even 36” canopy) is not a bad distribution. One wouldn’t be flying in a gale force wind, so those parts are not going to drift too very far under chute(s) that size.

The Centuri and Estes Saturn V lower segments both recovered under twin 24” chutes, and while twin chutes loose a bit of their overall drag potential when blossomed side by side, the lower portion of those Saturn Vs only weighed maybe half a pound, and they would tend to recover fairly rapidly under those two 24” chutes.

I think you'll be good with the two 30" chutes.
I used the descent rate calculator at Payload Bay and it says that ONE 36" chute for that weight rocket is enough (15 fps descent rate IIRC).
Separate chutes is not a bad idea. Or a really long shock cord.
Nice job on the finish.

If you don't have a big field and need to keep it safe, take a look at the F52 Blue Thunder 29mm Hobby Line Reload.

I've used these on 4" NCR by Estes Patriot Rockets with no problem.

If you are flying from a large field, then disregard.

Today, I'll shoot the dull coat.

Humidity is 32%. Wind is cooperating. No bugs.

STAND BY!

If you read this obituary then you'll know that I screwed up the dull coat: Jeffrey Smith (USN) of Aurora, Illinois (home of Wayne and Garth) hanged himself today with Duluth Trading Company boxer-briefs. He's survived by an extremely pi$$ed-off wife, (2) stupid cats, and (1) yappity mutt.

I don't think that is the recommended usage of any product from Duluth Trading Co., let alone undershorts.

Jeff-

Remember my admonition about the underwear! Don't do it! I still have the nice, clean rope we purchased for that very reason during your last 'crisis'.

I'll have the package on 'standby'.

Thanks, but I won’t need the rope or the skivvies to end myself because the dull coat is EPIC!
