Aerotech has just released that many of the glider motors are now discontinued until further notice, just the E-6, E-7 remain in the lineup.

These were on the chopping block along with a few 24mm standard reloads good for heavier gliders like the E-11 and F-12

Thanks for sharing. I'm pretty sad to see most of these go :(
 
Wow. That is a lot of motors, especially for the glider motors. I am thinking that the 32 mm glider motors are about wiped out.
Yes, they have about 39 casings in stock for the 32mm but without reloads it doesn't do any good. Fortunately you can use the G-8 or G-12 single use as a pretty good replacement in a lot of cases but at much higher cost per flight....But it will mean the death of my 18mm kits that used the longburn motor, it's a bummer.

I never saw much support for the 32mm size. No motor mount tubes or anything on the market. Was that a more common component size in model aviation that AeroTech adapted to rocketry? Or was there another reason for that size?

I assume it was for proprietary reasons, although a BT-55 would fit. It was only used in the Phoenix rocket glider commercially.
 
Dang. I liked many motors on the list. D9, F12, G12... E11 was meh. I have some of each still.

The second list is more disturbing. No more H112 or any other 38mm FJ? No L1500T? Wow. No more 98mm coffee can Ks? Darn.
 
Aerotech in the AT Open Thread stated the listed motors (full list)are not likely gone permanently but would/could be produced occasionally (maybe once a year). Kind of reminds me of ammo reloading, many calibers of brass are only produced periodically (32-20 Winchester is one iirc) and in limited quantity.

It's a crime and a shame that the only cartridge to have its own blues standard is so little known and loved today.

(Edit: then again, it's a pretty dark song all things considered.)

It makes sense. Why have the machines for a slow-moving product moving all the time when this other approach satisfies existing demand more profitably?

An creates an artificial demand (think Disney vault) for periodic items, at the same time it free's up equipment for making more of popular loads.

It was done to keep people from trying to 'fly' the R/C glider motors in model rockets.

Interesting note. An Estes D12 motor will fit in the RMS-32 casing. We took a D12, put an E6 nozzle and O-ring over the D12 nozzle, screwed it all together and fired the motor. This raised the motor's performance because the case could handle more pressure. The total impulse registered as 22 N-sec, a low 'E' motor.

Now that is an interesting piece of trivia!

That’s funny, I was hoping to do exactly that one of these days. Get rod clearance speeds somehow, perhaps an oversized piston launcher, and have fully electronic deployment. But I guess the goal of keeping newcomers from just shoving it in a stock Initiator without knowing anything is fulfilled.

Wow, Frank . . .

That is really going to suck for your RC gliders, that use the long-burn motors.

What are your motor plans, going forward ?

Unfortunately I don't think that will pan out in a lot of cases due to required minimum order amounts, typically 100-200 motors or 3-packs for them to consider a run. For example the 18mm D2.3T RC reloads I was told I would need to order 200 3 packs for them to consider it, that's nearly 3K investment for a stock of about 3-4 years of sales and personal use flights. I've had them do custom runs of the single use E-6RC plugged motors so my customers would have a SU option that didn't want to invest in casings, it's usually 100 motors minimum and that lasts me for about 2 years.

It's hard to sell kits for something that only has one motor source because people want options. In this particular case there may be someone willing to do just that for the internats teams usage that may allow me to keep flying them myself. Not sure there is anyone willing to do that for the C3.4 reloads or others. We'll see how it pans out.

I certainly understand the business reasons for doing it, just sad because these are a really neat little motor.

I understand your perspective and definitely sympathize with you. AT cut the motor choices for the 38/120 and 38/1030 in half, but the motors you need are very specific and not having choices definitely places limitations on you.
 
As I dont see it on the list... would the F12-5 still be available? From a glider perspective, I dont load the EC so i dont really worry about the delay length.

in HP, I am sorry to to see the L 1635M and the M1305M go. :-( I have an L1365M I am hoping to fly next month. Been looking forward to that one.

Aeroteh confirmed the f12 5-second delay is still going to be supported

H999 flown several. Always impresses the crowd! Try one in a LOC High Tech H45 :)
I49 also fun in the High Tech
Not much of a fan of the J and FJ motors.
I don't have any of the 1 grain cases, I just use the next smaller diameter.
Sorry to see the K250 go. Need to go back to the original SU motor. :)
DM people love even with the crappy performance, M not so much.
Sorry to see the L952, L1500T and M750W go, I like both.
