Anyone know if the I125 has an offset core?

Pretty sure all of the CTI longburners are offset cores.

I love CTI - easy to assemble, quick to come to pressure, and clean up is a breeze.

At the moment they are.

Flew the K4000 (1 grain 98) today on a Jart. The rocket is the limited run Black Saturday pre-sale kit. 5" rocket with a 4" hole. The motor was originally going to fly on a Gizmo XL. It was decided that the smaller rocket would be more fun. I will update this post soon and put up the video, for now, here is the Raven file. Awesome motor Jeroen!! Thanks for the opportunity to fly it. Another "giggle inducing flight".

Limited production run, apparently.

I want to see a thrust curve...

You can look at the Raven file posted above. Zoom in (takes a little practice). Not much to see. On... (0.6 sec at cold) ... off. Flat trace.

Here is the video. The laughter is very funny.

Jeff,
That is a really nice shot. Thanks for posting it. I'm looking forward to see some green around here again. Probably 2 months away.

Our kids launched a TARC rocket today using a 51F36 and there was some pretty significant thrust vectoring. I probably should have looked into it further, but when the kids were working on drilling the delay I noticed that the core appeared to have an unusual shape to it. I assumed it was manufactured that way. It wasn't until the bad flight that I looked at another motor to see that its core was a perfect circle on the better motor.

How common is it to get a motor where the core has this sort of problem? I'm assuming I could have cleaned it up myself, but I didn't think of comparing the shape to another motor because the defective one had a shape that looked somewhat symmetrical. Is the core molded in such a way that that could be some 'flashing' like that accidently left behind?

Cores are drilled. There can be a small "donut" from drilling left in the core. Or some shavings from the insertion of the pellet. None of these would cause thrust vectoring.

Is that a 54mm reload?

It's this stubby thing.

(The metal tube, not Jason.)

So. Much. Want.




Not Jason, the other thing.

If it has such a fat nozzle, why doesn't it stick far out the back like the XL nozzles do on the 2900+ newton motors? Just curious.

Also, the lack of tracking smoke must make it difficult to follow...

Multi-throat nozzle.

Also, the lack of tracking smoke must make it difficult to follow...

That's exactly what the original customer wanted....

Jeroen , I am sure that you signed a no information release with the client of the K4000 , but how far off would I be if I guessed it was for some sort of shoulder fired missle ? That is the only reason I can think of for a short burn high thrust stubby motor with no tracking smoke .

Ready for certification. We are planning an old-fashioned multi-day session for this year. Spring starts in May here. -4F this morning.

The burn time is about 10 times too long for that. I would not want to fire this thing of my shoulder ;-)

I'm pretty sure (based on Wikipedia) that shoulder-fired missiles are usually staged: they have a really REALLY quick charge which spits it a safe distance out of the tube, at which point the real propulsion motor starts up.

Meaning there is much more than that one motor...
