Wow, very cool.

Agreed. Everything posted there just made my list for next year.

That J1000 is a Bad. Ass. Motor. I was really pretty surprised at how much noise came out of that little case. It picked up and threw that 4in rocket like a toy. So fast it outran my camera. Sorry about that!Had a great day of Loki flights, only could squeeze in 3 flights due to time constraints but most went well. All of the Motors preformed flawlessly, two rockets took a small bit of damage mostly cosmetic. The J Rider on the other hand suffered a catastrophic recovery problem that I will detail in the build thread of the rocket.
As for the J-1000 it functioned flawlessly and from the data dump from the Eggtimer it hit 5711 feet. Not bad for a six pound rocket, i'm still new to the data dump of the Eggtimer so I will get a speed and and a event graph tonight it looks like its 357ft per sec which is around 240mph.
Unfortunately it had a high speed ejection and it came apart at the top. I found all of it but the chute and one fin, its pretty beat up and probably a loss but all in all not as bad as you would think for a fall from 5700 feet. As bad as the shred was I certain it would have broke 6k had it not premature separation.
It was an awesome flight almost everyone came to the flight line when it was announced, it made big ruckus and got up and went in a hurry. Lots of ooos and ahhs and aaaa my ears! I love this motor and 1200 case! :headbang: Alex got a video he said he would post.
TA
I need to get a rocket that fits that case asap.
Pics of my Formula 75 dubbed Land Steak flying on a Loki 38-480 I210 Red. Beautiful flight to 2688 I think.

Here is the flight data. Considering it weighed almost 6.5 pounds on the pad, it was a pretty nice flight. And yes, the 118 in the altimeter bay for the temperature is correct. Welcome to August in SC.

Assembly was fun. SUPER easy to build. Also, a little bit hard to disassemble (I bet the Hilton was wondering about the black stuff in the bathtub from soaking the motor to get the &*($%^&*((*&^%W liner out... )
For me the hardest part of assembly is getting the nozzle o-ring on with greasy fingers. Scott, any tips?
Thanks again for sharing the launch photos guys. Keep them coming!
If you have trouble getting parts out of the motor case, the easiest thing I have found to do is to heat the parts back up. Sometimes the dash board works with the defrost on high heat and let it sit there a while. Things tend to expand slightly and loosen things up a bit.
Also, push the liner out from the nozzle end. If you are trying to push the liner out with the forward bulkhead, there is nothing between the liner and forward o-ring so the liner will compress the o-ring making it rather difficult to move anywhere. Pushing from the nozzle end, you have the shoulder on the nozzle and the o-ring is usually melted a bit so it isn't compressed like it is before firing. It's much easier from this end. Give that a try next time.
Ask and you shall receive Carlo! Some things are easier to show than tell.

So will the 1200 k-700 use a single use noozel?
Todd, I didn't know you were French. I never noticed the accent before. Go figure..... LOL
It's more a issue of heat than throat size. Believe me, if I can get away with a graphite nozzle, I'd much rather take that option. However, it also costs about 100Ns of performance from the loss of propellant length and nozzle expansion. Is that worth an extra ~$15 for the horse power? I' still have to test it in the same configuration with a graphite nozzle to measure the casing temperature just to be sure, but I got what I was after in the test.....the start up and level off pressure and they were both spot on the money.
Is there a Loki thrust ring option with a slightly smaller outside diameter and thickness which will fit with these retainers?
So what has to happen is the case cant get to hot for the graphite nozzle, humm IC How long is the burn? I guess the catch would be if its the same cost or more than a comparable 54mm K
I want to say thanks to Scott at Loki. I flew two of his I405s today and they were outstanding. I know they are just I motors but they don't act like I motors. They act like I motors with a bad case of rabies contracted by drinking an infected can of Red Bull. They frighten most J motors.
I am in the process of building a Wildman DarkStar 3" limited edition and I have my mind set on using the 54/2800 K350 Moon burner. I would also like to use the GLR tailcone, however the Loki thrust ring is tight on the outside diameter and a bit too thick for this retainer. You can see from the pics below the motor will squeeze in as well as get the snap ring into the retainer but it is in on a slight angle. Is there a Loki thrust ring option with a slightly smaller outside diameter and thickness which will fit with these retainers?

The I405 also sounds different than other I motors. It's obnoxious.
Kosdon, AMW, nor Loki hardware were intended to work with any of the Slim Line retainers.
I inquired about this a few years back
Giant Leap never supported those Motor Makers.
Aero Pack tail cones will work with a some modification.
