Loki Motors

[Tim Thomas]

8) I have picked up a pile of 38 Loki motors to try out at MHM. If they work out as Chris and I expect, I am thinking of pushing Ed, the owner of Giant Leap, to let me carry the 38 and 54 line of Loki Motors. I will be working with Ed at LDRS, and I think I can talk him into giving Loki a try. My question is, what do you guys think? Is there interest out there? Jim A has AMW, and John S has Roadrunner, Would another line of motors go? Fell free to jump in… 8)

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 is obviously a niche market in and of itself. I think you’d do well here.

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 one of the best motors for all out performance.

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’d like to try some of the 38’s.

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 not too bad. It is definitely worth investing in a good pair of snap ring pliers though (~$25) – I learned that the hard way (and yes, people are welcome to borrow my snap ring pliers too – they’re good for 38’s and 54’s, but I wouldn’t try them on anything bigger).

(warning – the I405 is prone to shred light 38mm rockets :D)

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

Here is what is cool about the Loki Stuff. Its all based off of 1 formula but run at different Kn and pressure. Some manufatures run different stuff like catalist. Loki just bumps the KN up around 400 and runs the I405 at about 1800psi. Where as the longer burn motors are the same propellant but with one long grain in a offset core hole. They run the Kn much lower and a lower pressure closer to 600psi. Then most of their standard burn stuff the run KN from 28 to 380 with Pressure ranging from 750 to 1000 in 38 and 54mm stuff and the larger 75mm motors and 98 and all the way to 6″ stuff is run around 750 to 800psi at a KN of 280 to 300. I do like their performance and the ability to spread it out.

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 performing (commercially produced) motors for a given impulse class, like the K350. Obviously it depends on what you want, but I have a new bird that is just begging for a moonburning K.

Sorry if that was OT, Didnt mean to say they were bad or anything like that. I know for alot of people they measure the performance they get with the ISP that is delivered. Performance can come in many forums depending on what you wish to look for. In the case of the K250 with its long burn it is a very cool motor.
