They came that way for a period before switching to the single throat nozzle to allow usage in CTI cases. It's the correct nozzle.

Updated post! Make me an offer. Need it gone!

Is there a timeline for the K62N? I was thinking it was supposed to come out last year, but there were problems iirc. I have a project that needs this motor :)

I like to glue the coupler in and have a stepped bulkplate on each side that is removable. So on the main side, you can just pull on the shock cord and the bulkplate comes with the all-thread attached. You can make your charges and drop it back down.

Finally getting back to this after a year and a half. A little tease here with updates and video within the next week :)

Updated inventory and price.

Looking for a 4:1 nosecone that will fit a standard 6" tube. Thanks

I can attest to this. An actual racecar makes rockets look reasonable lol

Yeah original plan was to have it ready for LDRS this year, but I didn’t want to rush it.

No plans at the moment, but nothing is impossible!

don’t talk to me or my son ever again

54mm loads with the Medusa nozzle have the nozzle to liner oring. It can definitely be a pain sometimes.

I have video - just need to edit. Hopefully soon

Update on the big Sumo! Braden and I had our hands full sanding the big Arcas before we left for LDRS - so I just didn’t have time to finish the Sumo even though it was structurally complete. I just need to put on the decals, figure out the recovery, and put on rail buttons/motor retention...

I’ve haven’t seen any 360 loads with a seal disc yet, but if it comes with the thin oring and a phenolic liner that’s what it’s for. I did notice the I357s started coming with phenolic liners a year or two ago, but they still had a phenolic insulator; no seal disc.

I’ve had this happen with M840s and M1830s in AT cases. Those both have CTI’s small nozzle. All the M685s I’ve flown have had Medusa nozzles and I don’t think I had a problem. Doesn’t take much expansion for it to hang up on the closure though.
