Let those closures soak in 50/50 water/vinegar overnight and they will clean up like new with babywipes--easy. Or, at the field, I just use babywipes and call it good until they can soak overnight in the weak vinegar. 100% reliable and the best motor cleaner I have found, plus you can get jugs of it from Walmart for nothing.

When I was new, the Aerotech motors intimidated me. Before too long, after a dozen+ 29/40-120s and HP motors or so, I could not remember what the apprehension was to begin with. So far, they all go together about the same--takes just a few minutes to make one, following the directions line by line.

Knock on wood, but since I started flying HPR in 2008, I have yet to have an Aerotech motor failure of any kind. I've gotten to the point where I would rather fly a 29/40-120 reload than a SU 29mm motor just because I *know* I'll follow the directions to a 'T' and not miss anything--putting the motor together myself actually builds my confidence level as the button gets pushed.

Not trying to start a "my motor is better than yours" thread--just pointing out that your opinion may change over time and with a little experience. I fly CTI too when I get a chance, as well as snap-ring motors like CTI, KBA & AMW/ProX. Truth be told, IMHO, the snap ring motors are easier & better bang for the buck than anything else...look at the CTI 54/2550 L1276R motor for a cheap $108 at Wildman for the case in point.

My bad experience is particularly the 29mm HPR forward closures. It's not getting the grime out, but rather getting the delay insulator tube out.

I love assembling AT motors, though. I too have never once had a failure (sub-nominal performance on endburners, yes, but no failures).
 
The original/classic AeroTech I65 motor was 54mm in diameter.

A truly unique motor in its time. First ones I had were low smoke with a delay that I flew before the WL propellant plug types that I had purchased. The J100 was nice ride too for 2" diameter and 3" diameter kits that were light in weight.

For all the old timers remember when Gary from AT and Ron from LOC got together and said you build the kit and I will make a motor for it. And the LOC EZI-65 was born. It would be great to have a EZI-65 with the AT I65 motor.

Yep, I remember drooling over the 87 LOC catalog (my first) and the photo of Gary on the cover with the EZI. First EZI I saw fly on that motor was at LDRS-VIII.

I agree that EZI-65 with the I65 motor would be a great combo to see again. Old timers remember when Ron and Deb were motor dealers and you could purchase those motors directly from them and pick up at the launch. Ross with Magnum too right off the back of his truck ...

;)

I also have fond memories of Ross's truck....bins of goodies just waiting to be bought. Unbelievably, he would come all the way out to Black Rock for some of the AeroPac launches in the mid-90's. That's a long drive to go to a club launch!

I flew a couple I65's back in the day...my favorite flight was an in a heavily modded Loc Onyx:cool:.
 
I always have wanted to build a min dia rocket but never wanted to risk the hardware the new AT DMS have changed all that now. This I-65 looks like a real nice motor to give it a go.

I flown my stock EZI with a J90. Nice flight. My EZI needs a new airframe tube and bulkhead due to some shot-gun damage.
 
And a shotgun was used to get it out of said tree?:facepalm:

I would have used a chain saw myself...Just sayin'...:wink:
 
My first single use AT did not end well. The H motor destroyed the rocket. Not sure if it was a Cato or what it did. The bottom 1/4 of the motor bent.

Uh oh. Was it last weekend? Which motor? Did you see the post in the propulsion forum about some issues with some DMS motors? I clustered (2) DMS H195NTs with great success.

Those were the days! I remember the early 90s Danville launches were you could wander from motel room to room and buy tons of cool stuff. Ron and Deb and the Loc crew, Rocket Research out of Richmond, Propulsion Industries and the great 29mm H-140 and I-285 motors, Rocketflites big BP motors, and on and on. What a great time!

I had a chance to have a beer with Gary over the weekend, and yes, the I65 is in the works.

Exciting? You bet.

What's better yet is the longer motors that AeroTech is looking at in the 54 DMS line. There's some legendary motors of a very similar profile to the I65 that are coming back.

I'm in line for some of this stuff:cool:

I should add that there were also several demo flights of the new EZ delay system as well as the 29mm and 38mm DMS motors. The 38mm motors are made with fiberglass cases, linerless, and you can see the individual grains through the wall of the case. Awesome!!
 
i can remember flying I -65 ,j-125, k -250 in both aluminum and fiberglass casings even seen k-125 and L-250 98mm 20 sec burns . still have single use k- 400 from 95

The K125 motor was not very practical. It could barely lift it's own weight.

The motor was modified to use White Lightning propellant. This dropped the burn time to 'only' 12 seconds but it could lift a light weight rocket.

I built a 4 inch diameter by 9 foot tall rocket to use the K215 motor.
The model was flown at LDRS-8.
Impressive smoke and flame! :eyepop:
I even got it back and still have it. :)
 
Killer stuff... and great to see the return of the classic single use motors.

EZI-65 can now live up to the name. Oddly enough, I never flew an I65 in mine, did fly a J100 though :) , stock kit handled that fine, never to return to earth, did an I65 in an original NCR Phamtom 4000 HD ( think short no payload version with 54mm mount, direct from NCR, foam cone, too ).

The 98mm single use would be a great motor to see return - one of my ALL TIME fave flights was my Loc Custom K-Load kit ( 95% stock with no glass, but ebay for dual deploy ), on a 98mm single use, no smoke K250 .... ask the MARS guys who saw it. dead striaght boost over 6500 feet... and that with the added electronics weight,I have to think Rons original , no added weight, motor eject version, at LDRS6, in the thin Hartsell air, went closer to 8K ?

still have to reminisce about the old days, have to think the 90s was the golden age of HPR, more motor choices, manufacturers, etc... now has lots, but seems less choices even now than a couple years ago when I faded out of the hobby for a few.

I had the same issue with my first one. I think my motor thrust ring failed?

I could see that happening. I think someone mentioned that happening to them on here. I bet the vast majority of the time the thrust ring works fine, but it wouldn't hurt to reinforce the forward circumference with a little ring five minute epoxy
