Why wrestle with trying to make an E15-4 work (or the guilt of modifying
a delay), when AeroTech could just make everybody's life easier and
release a motor just for that rocket??
What say, Gary????

Of course, if they make a short delay E15, there are lots of other things
to fly them in....
My opinions only.
Seriously tho, looking at building with stock parts & yellow (aliphatic) glue
(that's Franklin Titebond, if I mispelled the term). May fill the vacuform fins
& definitely replace the stock s/cords. Looking right now at the AT E15-4. I'm
not HPR certified, so I'm not even looking at ejection charge mods-going
straight single use, 24mm. I think if I build & paint light enough, it'll be a
good motor for it. Thoughts?
See ya'll on 7.16!!!! (Probably the 20th too, my aunt worked on the real

I've been flying my 2001 version on the E15-4. I can't imagine any other
choice for the single-motor configuration now. All my attempts with Estes
D12's resulted in zero- altitude chute deployment. I'd actually given up
flying it until I discovered the Aerotech stuff about a year ago.
Build it stock, although the shock-cord change is a very good idea, of
course. She doesn't *really* need any additional nose weight to fly on the
E15, but it can't hurt, either. Nylon chutes might be a good idea too. I've
found that, even with extra wadding, I'm constantly replacing the plastic
Estes chutes when I use composite motors.

Back in my youth, I had a Sat V that had simply survived too long and
was looking at a third facelift. I decided to "suicide it". It
recovered just fine on a D12-5. On a D12-7 it ejected just after the
first bounce. The replacement later died in a tragic car accident.
My tool box crushed it.
Well, I know I'd grab two dozen right off the bat without even thinking
-- and I know Earl (Cagle) would, too. There's 10% of that minimum
right there in two orders. *Surely*, surely, we could rustle up a
demand for 500-1000 of these motors.
(Heck, might get 4 dozen <g>).
Note to Ross: We're talking about a special run of AeroTech E15-3
("THREE") for the new Saturn.
Note to Gary: As Cochran noted, there are *other* uses for such a motor
-- and you would most likely see a decent 'return business' over the
coming years. This motor would become the 'de facto' Saturn V motor
and, as this current 'euphoria' indicates, you would find tremendous
'brand loyalty', I am assured.
