SAN JOSE, California USA — Rouse-Tech now has the full line of 98mm hardware back in stock and ready for shipping to dealers. Rouse-Tech owner Tom Rouse said, "It became a futile effort to locate and purchase tubing for both the 98mm and 75mm hardware over the last year or so."

"Either the mills were not making those special sizes any longer, or all the supply being made was being shipped to China," Rouse added. "Regardless, it caused us a problem. To solve this, we invested a large amount of money to purchase raw tubing in these sizes and ordered 'mill runs' direct from the aluminum manufacturer. As a result, we now have over three years of supply of both 75mm and 98mm hardware ready for shipping!"

With all of the new and various sizes of AeroTech propellant being introduced, like the popular Warp 9�, Mojave Green™ and long burning motors, it was important to get the hardware in stock as soon as possible. Most people want to have their hardware when they build their projects to test the fit, so they can build properly. That's why Rouse-Tech tried so hard to get this hardware in stock in the winter so customers can make sure they have their motor hardware for the winter "build season."

Please contact your dealer to place orders.

I always order mill runs of aluminum. Only way to go. The burn-rate stated indicates the case market has neared saturation and the new adopter rate is low due to recently and massively increased federal regulation.

I suggest less regulation, internal and external, as a means to double your casing burn-rate. After all, more rockets flown is always better for everyone.

Hmmm... I don't know. I had a Rouse-Tech 38mm case split/crack down the middle of the thread section on its first flight at NSL in the summer. Ruined the rocket. Tried to contact Rouse-Tech and absolutely no reponse. I think I'll stick with Aerotech which has always provided wonderful customer service!

I had a 54mm Rouse-Tech case on the first time out with a K550 develop a bulge near the top end it was almost stuck trying to pull it out through the motor retainer. I ended up in contact on TRF with Tom Rouse and he told me to send it to Aerotech, which I did and got a new case. It was replaced with an Aerotech case not as cool looking as my nice blue Rouse-Tech case but I was back in business in no time. The liner was too short, I think is what they determined. I know they appreciated that I did not take it apart and sent it to them just as it was flown. I did take off the forward closure to see if I did something dumb but put it right back together. Took most of a week to get things lined up through emails to get the how and who to send it to but they where glad to help.

i have flown there 29mm cases and never had a problem. but every time i have a aerotech G64 the liner is to long and i have to cut it down some. so the foward and aft closurs fit correctly. that propelrnt has a huge flame though i love it

So, to make sure I understand correctly, everytime you fly AT G64 motors in RT cases you have to trim the liners?

Do you have to trim them to fit AT cases? I have never had to and I have flown quite a few. I'm wondering if your problem is because the combination of RT cases and closures results in not enough space for the liners or if you have gotten reloads that had too long of liners.

I think it might be that there were a few liners that were a bit too long, Steve. I flew a G64 in an AT 29/40-120 case last fall that showed the same symptom - the rear closure was about 1/16" away from bottoming on the threads. I disassembled it, checked that the o-rings and nozzle were positioned correctly, but it still was a tiny bit too long.

Guys, most of the time your bottom closure will not completely tighten to the bottom of the case with Aerotech reloads. I can only think of a couple of time this has happened, and I have never had an issue with an Aerotech reload. Do not be conscerned if the rear closure has a small gap-you do not want to overtighten it and ruin the rear o-ring.

Has any of the KBA AMW-clone cases been manufactured yet?

#9 Re: Rouse-Tech restocked and ready for the next thee years

I hesitate to ask this as I'm sure it will open a HUGE can of worms, but is a KBA-AMW clone case the same as a AMW case? I know physically they're nearly identical and if you ask AMW they're not, but at the motor certification level, are they?

The certification document that NAR issued to AT for the K1750R KBA-AMW motor has a caveat on it that says:

Quote:

Certified for use in AMW 54-2550 hardware only.
No substitutions allowed

source: http://www.aerotech-rocket...2550/k1750r_nar_cert.pdf

Does this mean that it requires true AMW hardware? I don't know any RSO that would think to check which case the motor was in and even if they did think to check, should they deny the flight because the case is anodized in gold and not grey?

First, you didn't create the can of worms, so don't feel bad. It has been sitting there fermenting, waiting for someone to ask the question.
Didn't Kosdon East sort of morph into AMW? If so, would that mean that Frank Kosdon approved the use of his reloads for use in what are now AMW cases?

Frank Kosdon also licensed Aerotech to make a line of reloads for his cases. That was the KBA line. If those licenses are still in effect, then does that mean that KBA reloads in AMW is okay? I don't have a clue.

The Kosdon agreements used to be (may still be) on the Aerotech site. They seem to say that Kosdon hardware could also be made by AT. I think that is the basis for the Kosdon/AMW clone cases by AT.

I'm with you on this. This is a burden to put on an RSO. I don't memorize the anodizing dye colors used by each motor maker. I don't care to. So, should the manufacturers be forced to engrave their cases so we can immediately tell who manufactured them?

Similarly, what about the amateur machinist who makes his own cases and uses commercial reloads in them. With no case markings on the Kosdon style cases, how does an RSO know? They could easily be dyed the same color as AMW or Kosdon cases.
