    Well I see AT is trying to improve its 24mm motor reloads. If they can do better and make a longer 24mm casing than CTI, they will win a bunch of SEDS interest on a national level as a 24mm H class motor doesn't exist. SEDS will gladly take the longer burn times with additional case length then reduce the fin span for stability and maximum drag reduction. Most SEDS teams are dropping $500-600 on L-1 motor hardware and reload options a year, so $48,400 is out there for grabs. Lol.

    Of course, mea culpa.

    I like AT 24/40, 24/60 but do wish they'd develop longer 24's that -don't- require the HazMat. An HPR AT in 24mm is a pretty big wish, however.

    Me too, I would love to see some longer 24mm offerings from AT.

The results will have the unit “seconds”.
    The Specific Impulse of all White Lightning propellant should be very similar. I just calculated it for the G64W and it was about 205 seconds.
    The certification document does not report Specific Impulse.

    I love the hazmat free 38mm reloads and look forward to seeing a whole product line of them.

    I'd still like to see a whole bunch more reloads for the 75/6400... I haven't flown the M650 or M1550 or the L1250DM... M650 too weak for my WAC Corporal, M1550 - reds dont do much for me, the L1250DM might be too wimpy for the WAC. Maybe I need to trade up for the 7680 and just use my RAS's...

    The H130W 38/240 and I180W 38/360 are shipped without hazmat. Those are the only two I'm aware of.

    We have a US Mailable J520W which was certified but only as a plugged motor. We are working with TRA to figure out the delay issue so we can submit them for recertification shortly.

    I preordered a J520W .. will be a fun non-haz motor .

    Just looked up the latest price sheet and saw this nugget :

    15504P O5040X-PS 98mm DMS™ (Plugged) Requires NAR or TRA Level 3 Certification

    As others stated, J520W is the new addition to the non-Hazmat list. Alas, it's also on the "I can't order it anywhere" list.
    I just placed an order for 2 out of 3.

    The best part is that non-
    HZMT H130W (210 Ns) is roughly the same impulse but cheaper than the equivalent H-motor from the other non-HZMT motor supplier.

    I180W (326 Ns) is cheaper, but way less thrusty than I201-LR.
    J520W (731 Ns) is, unfortunately, both more expensive and less thrusty than J528-LW.

    Charles, can you do something about the list pricing ?

    The J528LW is not us mailable though, so the comparison isn't the same.

    I have a question: Why has the supply of RMS-29 40/120 complete hardware almost completely dried up? None of the vendors I would like to buy from have this item in stock. This issue was almost as bad back in June when I started my upscale Kraken build. I was hoping to begin acquiring parts for the replacement build of the Kraken which was lost yesterday.

    +1 On this.

    I purchased a hardware set and was notified a day later that it was on an indefinite backorder. I was asked if I wanted to wait or get a refund....

    It wasn't an order from AT but I won't name the vendor.

    I suspect that the exclusive hardware manufacturer status has something to do with this. It wasn't such an issue when you could also buy AT compatible hardware from a 3rd party (2nd party?) manufacturer.

    Because since last Spring......NO one has been making any AT hardware to sell!
    There is none in the pipe & vendors stock has dwindled to zip.

    It was explained earlier in this thread, Aerotech is currently beyond capacity at making hardware. With CTI down a lot the past year or so and Loki having the same issues but being way smaller a lot of business has come Aerotech's way. They haven't stopped making hardware, you should still be able to back order hardware, though it takes time (I think it took 3 months for my 98/7680 complete motor).

    Ah, I see. I did a search on the forum for this issue but I had queried with reference to the 29/40-120. Anyhoot, that explains a lot. Guess that means Aerotech is in a bit of a pickle as long delays across their products lines can and will generate quite a lot of negative PR. As to back-ordering, most of the vendors I deal with do not offer it. At least not via their respective web presences......

    Sigh.

    A little recap from last month:

We are also ordering much larger quantities and both of these factors add time.

    It looks like AT will catch up, but there is some lead time.

    I'm sure they will.
    I'm not in a hurry, though I do have a 29/40-120 motor on backorder.

    Also realize that you are competing with 700+ TARC teams on semi-unlimited (parents/school) budget, all rushing to buy up dozens of 24-/29- motor cases and reloads. Temporary supply disruptions are inevitable, especially given that CTI motor stock has not been getting replenished for a few years now, so everyone is flocking to AT for mid-power motors ...

    That's too bad.

    AT should license the ability to make hardware and focus on single and reloads. Money on both ends with less hassle.

    It's a good direction that will clear any negative PR for availability.
