I’ll weigh it tomorrow sometime; will do it with everything minus motor/case.

It looks good to me What’s the weight?

that’s good to know about the J/I impulse motors. any H recommendations?as for progress…did a very thin skim coat of epoxy, still need to smooth and finish it all up. Next time I will definately use the vacuum bag system…   Read more»

Well, the Loki I405 is great in a Miranda, as is the I110 (just ask nate). Slightly tamer are the Aerotech I161 or the I218. For J motors, the J90 is my preference, but any small to mid J other…   Read more»

it will definately be good for L1 and L2.I learned a lot and the next one will be better, but that will be a while from now…don’t need to be thinking about another one just yet; need to FINISH this…   Read more»

Looks VERY nice, and even though you did use polyester resin (never used the stuff honestly, so I can’t say much about it), it should be more than strong enough for the I600 for L1 and the K1445 for L2,…   Read more»

Looks pretty damn good to me!Warren

updated photos, almost ready for paint! (white paint is to identify high/low spots)

that is all correct; epoxy is definately better than polyester for CFRP. was one of those situations where it was available and free…hard to pass up :Dgot lots of sanding done, looking good now, will have photos later!

Polyeter resin can work ok,, But it does not have the great bonding strength of epoxy. Ive done lots of Fg work for years (lots of it on cars and boats as well as rockets) and used the PR and…   Read more»

I actually don’t have rocketsim, I had a trial version, but it expired.Anybody in/around Denver got a copy I could borrow?

I used polyester resin, had a bunch laying around the shop. It smells 10 times worse than an epoxy. The CF cloth I used was a 6 oz twill (I think), again it was some material we had laying around…   Read more»

(will definately use epoxy next time). Did you not use epoxy? As for motor weight, a J350 is a bit over a pound IIRC. If you’re using rocksim though, it will take care of it. I doubt if you’ll need…   Read more»

If you’ve got Rocksim, the motor weight will come out in the sim. Both propellant and casing.Warren

not sure on weight yet, as soon as it’s done I’ll take it to the post office and get an accurate figure. PML says something like 52oz, so we’ll see how my pig compares; I used some pretty thick CF,…   Read more»

Those are some nice rockets! Very nice work getting the pics posted in the forum too. Well done.Warren

Very nice work. That thing should be bulletproof :D. How much does it weigh?

here are some of the other ones I’ve put together. all are scratch built withthe exception of the Aura (checker fade paintjob)

I am not into the mid size motors yet, trying to get started with E & F right now, and then G and then go onto level 1 Dale

Problem Dale is they are very popular among drug users, as people are apt to trust em more still. I like the fact that they won’t time out and for the life of me can’t imagine why some of the…   Read more»
