I intend to post new pics daily (or nearly daily) until I get them all up. This could take a couple of months as the collection is larger than it should be:cool:.

First post is an AeroTech G300 29MM single use. I have never personally seen one fly and think they have been OOP since the early nineties or maybe earlier. G-10 fiberglass case. Big old nozzle throat.

(ADDL INFO 12/1/15 - As I suspected, this motor runs Warp 9, which explains the propensity for delays being snuffed described by Initiator001 later in this thread)

Are you open to other people contributing? Such as this Syner-jet 22mm G117?

Here's a picture of my cloned VB Extreme 38 flying on the DPS G112. The "LS-HO" must stand for "Low Smoke - High Output" and it appears to be truthful...yes, the motor is burning.

I will need to pull my old tower back out to access the AltAcc data, but the motor case suggests a 0.8s burn. IIRC it was closer to a 1.5s burn. What's 0.7s between friends?
 
Next is a 54MM AeroTech I140. This is obviously not be confused with current 38mm SU I140.

C-slot, full I class with old low smoke classic propellant. Closest thing made today would be the J-180 for the 54/852 case.

Thanks for posting this stuff. I love hobby history. Very interesting to see what I missed out on.
 
Here is my meager contribution. Let's see if I can get the descriptions right after having only the attachment number to look at.

Here are an old AT E6-4, AT F10-4, AT G125-20, Vulcan G??-??, and a G80 for reference. The E6 had packaging but the other three AT motors had generic slip-on labels and the motor classification was written on the paper end cap. The Vulcan was not identified at all other than by on-line forensics by other rocketeers. The 'G' is just my guess due to the size and weight, but who knows. I don't have it with propellant any more.

Here are the nozzle views of the Vulcan, the G125, an AT G10-2, and a G80 for reference. I flew the G10 in an Art Applewhite monocopter. It went up, came down, broke one balance beam and then took to the skies for a nice long flight.

Thanks Dick!

Love your blog man.

I feel like posting another. This is a Vulcan I250 Low Smoke circa 1987. Graphite nozzle = very cool. This was supposed to be a full I class.

I flew a Vulcan I283 in around 1995...I think this motor would look very similar in the air.

Awesome thread, Jason! Enjoying watching the oldies; seeing if I recognize any! I just burned an I283LS last year!

If you don't mind, I'll throw a few oldies in here once in a while as well!

Side note/question: any old timers in here fly a Vulcan 54mm J250 low smoke? I'm intrigued/concerned about its grain geometry!

Thanks Eric. Please feel free to post yer pics.

I have never flown a J250LS, but I would bet it was offset/c-slot core looking at the burn time.
 
Not quite as old, but still historic. How about these Ellis motors. The long one is a J228 (38mm) and the short one is a J110 (54mm). I see an unrelated DMS H135 that I didn't mean to attach but can't get rid of.

Hi Jason,

Flew one of these at ESL 208. Took a second to light but once it did it was off!! Tried to adjust the delay as the 15 seconds is way to long for a 1000' flight. Here's the flight video.

I'm not sure which came first but here's another version of the G300 with a shorter delay and a different style case. Not sure why but the case is slightly longer than the green filament wound case.

I've got a few more I'll post along the way as well.
 
Love those huge throats! Would love them pushing one of my rockets even more!
