Can you say I140 skid for the pro54 1g? Incredible motor. Takes my 4inch paper Iris clean outa sight. Make a 54/426 DM and I'm good for a dozen reloads!

I thought the I500 was a single use version of the I435 all this time, but it appears to be longer and higher impulse than the I435. Any chance of a RMS version for the 38/720 case?

Also Super Thunder for the 75/2560 and 75/3480 cases would be amazing!

Some of that is possible, but we’re running out of room to manufacture and store additional new products. We may need to wait until our new facility is completed.

How can I get a single O-ring? I've got a 29/40-120 reload, a G64, that is missing the delay O-ring (3/32" x 5/8"). I don't have another reload to take the O-ring from to shop/compare with.

Did AT make an SU I132 at one point? I have two marked I132 (masking tape) but uncertain on manufacturer. Casing looks to be AT though. Is it possible that this could be from Ellis, Vulcan or other?

I measured one and mine was around 0.102" cord diameter x 0.633" OD / 0.427" ID. Having said that, while trying to get the ID measurement just right, I dropped it, it hit my shoe and is now under something, somewhere. DOH!

In my case, I will likely fly an E16 or some other 29/40-120 motor and when disassembling it, I'll grab the o-ring and re use it after cleaning and re-lubing it. Not sure most people would, but those o-rings seems pretty decent to me after flight.

Anyway, hope you can use the dimensions to get what you need. If nothing else, maybe you can grab a used one from a club member and if it is clean and soft, you might be fine, but use your own judgement.

Sandy.

It’s a #111 Buna O-ring, 70 hardness. You should be able to find them in a hardware store.

Yes we did. It was a 38mm C-slot White Lightning design that was pre-2001.

I132 in a Laser-LOC 1.5 simmed to 11000 ft. Flew one in 1989, still have one from then. First one is with a 54/1706 for size comparison.

Interesting, I'll have to get a photo of mine... Mine has a stepped down tube for the ejection well.

Thanks for the suggestion. Anyone else interested in such a motor?
Well, I am late to the party but I too would love to have more options for my 54/1706 + RAS. My 2.6" RIM-66 would be very grateful!

It looks like prices are about to go up about 10% across the board for Aerotech products, effective October 1st.

I'm not too surprised, since the price of AP has gone up dramatically, and I think that has already forced other manufacturers to increase prices, but it is a bit annoying.

New Price list

Again? they went up about 30% a couple years ago :mad: :( and the price of AP tripled.

The aft grain of the 54mm J180T has a bump out on it. When I put the starter in, do I stop at the bump or put it all the way to the top like I would with any other motor?

It goes all the way in. The chamfer on the slot is to make it easier to find the slot with the starter.

Thanks. That makes sense, since the core is not centered. I’m using it as the motor for the sustainer in a two stage, so I think I will add a Pyrodex pellet at the top to enhance the likelihood of the motor starting.

The J180 is Blue Thunder and lights pretty easily. The White Lightning version, the J90, can be very difficult to light. Note that the core is a rectangular slot. Make sure any pellet you use won't fall out.

I use blue thunder in a sustainer on purpose. But I’m lighting it with an ematch. I usually just wedge the pellet in at the top, but I’m going to have to glue this one in with some Elmers Glue All. it’s too thin for the slot and too tall to turn sideways.

I flew an N2220DM at LDRS. While it was great, it wasn't quite as loud/crackly as some others I have seen and this is consistent throughout Dark Matter loads. About 3/4 of the way through the burn it looks like a lot of the metals were slagged up on the inside of the nozzle and it spits it all out at once.

I'm not complaining, just genuinely curious if there's any insight as to where the variation in the sound comes from. Just the luck of the draw on how much of the metal makes it out at what point throughout the burn?
