If I can interpret open-ended suggestiveness accurately, are you continuing to imply that AT is catering to or snubbing vendors depending on X(order volume, business relationship, spite, etc...) despite multiple opposing testimonies from folks without stake in aerotech?

I think Steve's point has a lot of logic behind it. Larger vendors make larger orders that take longer to fill. I never even imagined them getting those orders in batches that could make it seem like they're regularly having fresh orders filled.



Are you insinuating that the vendor has NO motors that could possibly be used in any of your rockets?
Now I can understand them not having a very particular motor for a specific project or flight profile. Thus the frustrations from Handeman or others that do pre-order in an attempt to have that motor when they want it.

Just a thought...some vendors don't pay their past due bills on time and therefore their future orders are delayed until they pay up....simple business concept... But really just wanted to know what is that rocket in the right hand thumbnail under your posts? Is it some sort of scale or semi-scale thing? (I like it...)
 
Something else to consider with this whole 'just buy from another vendor' argument is that for a lot of people, there is only one vendor at the launches they normally go to, and if you're only flying a half-dozen small HPR motors per year (like I did for years), the hazmat charges for those motors become significant, so I try to stick with my on-site vendor when I can. Also, I have trouble with the argument that it's the vendor's fault, because it seems like Aerotech hardware and reloads are the only thing he struggles to keep in stock (with the exception of one or two other small things where I know for a fact there are production limitations). As someone else has again brought up the 'just buy way in advance' argument, I'd like to reiterate that probably 50% of my high power flights (and I know a lot of people are the same, though they aren't on this forum often) are for school competitions, and for those you have MAYBE 3 months of lead time at best to get motors before you have to fly, and we need multiple of the same reload for multiple flights (it was a nightmare last year trying to find someone with more than one J500 in stock, and we needed 5 of them).
 
I think there is a wire shortage also slowing things down... I noticed some new motors I found from Areotech, like a H123, have just enough starter wiring to make the length of the motor. About as long as my P#*#ter, which is awfully short!

I noticed that with the H148R I used for my L1. I think next time I run into a short starter, I'll just use my Portasol and add 6~10 inches of leader.
 
I’d like to say thank you to Aerotech for helping straighten out motor grains that I thought were questionable. I contacted my local dealer and Aerotech and a return of the grains was arranged through my dealer. Got my new grains in time for the first launch of the season. Didn’t have to follow up or bug them once.

Any word on when the next batch of K1103X's will come through? I know it's the only propellant X reload... so that may be why. Have had some on order from major vendor since Black Friday...

I also have a Black Friday order I'm waiting on - for a K1103. I emailed yesterday and got response today. Tim said they would be available by the end of the month.

Thanks... I may have a few more than one. :) Maybe that's the hold up!
 
Charlie was nice to us almost 4 years ago to start this thread, after many years of silence from Aerotech. Years ago Aerotech did have a thread to keep us informed of what was going on. IMO too much "noise" like what is happening to this thread killed the first one. I'm sure Charlie would prefer not to have to go thru all the BS to get to a post that pertains to why he started this thread. It would be a shame to lose contact with Aerotech again.

So, then how did the problem arise between SEMROC and ESTES ? Carl was, initially, using complete "Estes names" for long OOP kits . . . In the end, they had to be changed.
Click to expand...
We never had to change a name. Estes lost all rights to the names when Barry Tunick (some of you might remember the story) did not renew the names of all his kits. They did own the instructions so they stopped a few companies from copying their instructions and sending them along with the kits they were producing (these companies were using our parts). Carl and Estes had a wonderful working relationship before his untimely death.

I’m sorry that someone’s irresponsible posting put you in the position of having to respond to rumor mongering, Sheryl.

I wonder what newbies think of us when they scan through and read the threads on this forum. I’ll bet we steer tons of people towards model train sales.

I’m no newbie to the hobby but I am to this forum. This is actually my first post. It’s amazing how punchy people are. If it doesn’t build people up why say it? Who cares if someone asked a question that was snarky. If it truly was snarky, they will look bad all on their own - no need to point it out over and over again. Anyway, I’ll unfollow this thread now.
 
Do Black Jack reloads generally have more "rattle" when they're assembled than other propellant types? I assembled an H97J in the 29/360 case using the extended spacer from the 29 RAS and there seems to be an excessive amount of extra space. I even tried using the forward seal disc but still the same. Didn't have any parts left over...:D
 
Not sure about the H97J and RAS combo but the I200 (29/360 case) has some rattle to it after being assembled correctly. The instructions for that motor include the following: "It is normal if the grains rattle slightly in the liner"
after tightening.
 
I can't really get a look at a ruler down in there but it looks like about a 3 mm gap between the spacer and the forward closure. Seems to be slightly more than a "slight rattle". I've built a few and they have all rattled, but I'm not an old hand at it by any means1805434511.png . I'm sure there needs to be some space for the grains to expand once they begin to burn, this just seems excessive.
 
I've never had a space between the closure and RAS spacer like you are showing. In fact, more often than not, it's not possible to get the closures threaded all of the way down.

A rattle of the grains in the liner is common.
 
Took it apart and reassembled it. I don't know what exactly was going on but there's no rattle now, and the gap between the spacer and forward closure is gone as well.
 
I flew the H550ST RMS EZ this last saturday in my V2 ..what a blast !

Actually looked at the instructions to confirm I was using the correct drill tool , but was nice change from the traditional rms forward assembly. Also was nice to have that nozzle cap to hold in the igniter - the dms version has the gap filled flush .

Also happy to report the delay was spot on - drilled for 10 sec and it popped 2 heartbeets after apogee . Thanks to thrustcurve.org also..I did a quickee motor guide onsite.

Thanks ! Was nice to put on a show and stay under 50 clams .
