Sure – even better, ask Joe Hinton for one of the stickers if he has any left. There are even bigger ones available from the printer, but I don’t have the contact info for him handy.Warren

No problem at all, and I am looking forward to the flights :DIt should be a lot of fun, as they are really spectacular loads (and the lower cost doesn’t hurt either :))That patriot should MOVE – the I405 hits…   Read more»

8) Well, we will get a good look-see at the April Launch. Chris and his dad Ray are going to help Demo the 38 Loki line. Ray will fly his Standard Endeavour on the J528. 740ns. 1.3 sec. Chris will…   Read more»

True – I was thinking about the I405 nozzle when I wrote that. It’s a hair smaller than the nozzle on the AT H268 IIRC.

Takes different nossles for the I405 and I110 but same case. Great propellant! And that J528 is also a kick butt motor. Haven’t flown anything in the 54’s but have been drooling. I’d do that if I were you Tim,…   Read more»

1800psi?Wow…The cases are pretty thick though, and the I nozzle is pretty small, so I definitely believe it. They are very noticeable motors, that’s for sure 🙂

Gotta love those Moonburners!”If you build it, they will come”. I’m sure that is just as true for rocket motors as it is for baseball diamonds.

Well, I wasn’t commenting on propelant formulations or ISP numbers, that is simply over my head. All I was saying is that my understanding from people who have flown Loki’s, is that they seem to have some of the best…   Read more»

Actually, the 38’s if anything are cheaper than AT and CTI comparable loads. They are definitely nice motors – I’ve got all the 38 casings if anyone wants to try them. Hardware is a hair more expensive than AT, but…   Read more»

I’ve already got a Loki 54mm case and a K350 load so I’m a ready customer if you start carrying them.Warren

I’d like to try some of the 38’s.

Actually their perfomance is all based upon what pressure they are running at per given motor. The actual formula of propellant is pretty simple and not a Ultra high ISP formulation. Youd be suprised.

I would definitely try some out. 54mm would be my primary interest, but likely a few 38 as well. I’m assuming the cost for reloads and hardware is similar to AT and AMW? From what I understand the Loki’s are…   Read more»

Tim, I think each line has its own merit, and I believe you’d find a healthy appetite for Loki motors. The K350 is one of the great motors out there today; AMW has nothing in the long-burn category, and RR…   Read more»

Hi Warren,I too have looked for such V-shaped strips but the only thing I could find (pre-made) was the wood strips used in RC airplanes. I just opted for round carbon rods for my subsonic flights…The only other idea that…   Read more»

I’ve been thinking of the same kind of project as well. My thoughts were to make a mold for the fin edges.The idea was to cut strips of .062 G10 for the sidewalls of the mold.I’d lay them next to…   Read more»

An interesting question. And being a math/physics geek, I always wonder on what principles these prescriptions arise from.The simplistic view I have is air is rushing outward and too small a hole will cause a phase lag between actual pressure…   Read more»

Hello Everyone,I really appreciate all the help with the updated formula. That made a big difference !Instead of three ports at 11/32, I will need three ports at .21 inches.I may tweak a little towards .25 inch each, but not…   Read more»
