Yes, but are any of the throats on the nozzle other than the center one open on the J135? If not, it acts just like a single throat…

I know the J90 has a medusa with only the central throat open, essentially making it a single throat. I thought the other 54 long burns were the same. I’ll have to look at that and see – now I’m…   Read more»

The J135 has a medusa?I thought that the long burn 54’s only had the central throat open, essentially making them single throats…

It isn’t a rocksim, but I found the thrust curve…Here are the instructions for the M750One thing to note that I forgot about before is that the M750 needs a new, larger aft closure (it uses a medusa style nozzle…   Read more»

I’ll definitely try to post it here if I see a sim file :)I’d love to see one too 🙂

The M750 isn’t quite as big as the M795 (it’s 9,325Ns), but it comes as several grains that are glued together with epoxy in assembly. Result: none of the shipping problems or DOT issues that you have with the big…   Read more»

Very nice – I’m sorry I missed it 8)

Well, you could use a stubby 54 rather than a long 38 – that would probably make it a lot easier…

OK, he’ll photograph then :)I think he prefers that anyways.

Well, I can only be there on Sunday, and no guarantees about being able to stay for the whole day (so I can’t commit to teardown)…I’ll see if I can convince my dad to LCO, but I can’t make any…   Read more»

I have some good ones from GLR (I think they’re 5/16″) that I use in my deuce and a couple other big rockets – never seen or had one break.

We have rails for both standard and extreme size (1010 and 1515). I use (and love) the large rail buttons from railbuttons.com for my deuce – they work just fine on NCR’s large rails.

Still fun little motors – amazingly loud for hybrids 🙂

The M?

You’re right of course, after all, this lacks any semblance of being remotely close to cool:;)(I don’t think the flame:rocket ratio is quite high enough yet… )Honestly, IMO, the little stuff that goes really high is cool, especially when…   Read more»

Chris.. You are talking about flying it on the 2nd right? as the 3rd is a TRA research launch.Nope, the 3rd. My dad is TRA L2, and research launches can have commercial flights. I’m going to be at my HS…   Read more»

Because I only have 2 flights worth of CO2 cartridges assuming everything goes right, and if anything did happen to go wrong, I wouldn’t have much time to fix it before LDRS.On the other hand, it’s really fun and really…   Read more»

I hope EX day is reasonably spectacular – it should be a lot of fun :)I’m debating the Deuce as a possibility for the EX day, but it also may wait until LDRS for skids…

No – he’ll be down here taking pictures of my High School Graduation ceremony…Sorry about that…I wish I could see your launch…

I’ll be up in June for EX day. I can’t make the commercial launch, but with any luck there’ll still be some fun stuff 🙂
