RMS late 1990 R&R early 1990 TRM (clones of R&R) early 1991
Synerjet were loadable not reloadable.
Vulcan had reloadables well before R&R but those were for commercial deals, not released to consumers.
RMS were the first CONSUMER released (before DOT approvals, before TRA/NAR certs).
Jerry
Certainly.
ONLY the CERTIFIED pen may be used if they are TRA certified :)
This is because the ink becomes an integral part of the certified casing.

"I've replied back to some of Jerry's posts in a bit of anger but this time I think it's funny...someone has to step up and take the lead so to speak. And if you just get past Jerry's political crap thrown into most of his posts he usually does have some very good input that can be backed up and is quite reliable. All hail Jerry!....or not...."

WRONG....the first reloadable hobbyist rocket motors were the Jetex rocket motors and their pellet fuel....1948 I do believe...

I hereby concede the point.
However I do believe they are more accurately "airplane propellers".
They are incapable of vertical flight.
Jerry
No, it just means they don't trust jerry.
Nice try jerry, Frank's TRM motors were copied by you. Not the other way around.
snip of Jerry's hobby motor relodable history.
I have hard evidence. You ignore it with pride.
God bless.
It is ALWAYS about Jerry for Brian :)
^^^^^^ Just what would those be for...? Homemade rocking chairs? :-)
What "evidence"?? I've never seen any evidence that you designed reloadable motors prior to Kosdon, and you sure as heck didn't have any reloadable motors on the market until quite some time after everyone else did.
Oh, I get it now! In your mind, simply claiming to have evidence IS evidence. And when challenged, you just respond that the "evidence" is/was/would be ignored. How convenient for you!
The Synerjet motors and casings I saw at '91 Fall Danville sure looked reloadable to me. Unless you're saying something about their reliability or market longevity? They were also the first I saw that used snap rings
looked
Synerjet made reloadables, band later made some "kit" motors that were single-use and came partially assembled. The user finished the assembly. Perhaps Jerry was thinking of those "kit" motors.
I believe Kosdon was using snap rings before Synerjet.
I can't ignore what I don't see.
Why don't you post your "hard evidence" for all to see?
By the way, Do you have My fraud judgment? Interest is accruing.
I'd love to see that data. I imagine he did an SN curve. But I wonder if he used each firing as a cycle, or if he accounted for the frequency vibration of various motor firings.
Sorry, can't help it. I see data, people.

Wrong. I made several successful vertical flights with them in the early '70's, in a modified Estes Alpha (HT-50 IIRC with the cored pellets).
BTW RMS was developed in the late '80's, publicly demonstrated in early
1990.Gary

No it did not. A Vulcan "reloadable" casing was circulated around at launches well after the commercial introduction of RMS in 1990. It actually looked a lot like the CTI motor design.
ISP had "reloadable" RDS motors as early as 1983 or 1984.
Gary
I was not discussing "non-public" dates, and I did focus on "HPR market target" products.
As we both know there are plenty of commercial and military motors preceeding those that were "reloadable".
The RCS LUR motors on the other hand are "special" since they are non-metalic (USR made fiberglass reloadables for a while), and reloadable, and most notably molded, which makes them practical for a wide market.
Congrats.
