Saturn V - E motor?

Post by Q101 ro » Wed, 23 Dec 1998 04:00:00



Well, I just picked up my Saturn V. Boy, do I have a grin on my face! I've
decided I don't want to use a cluster.. Would it be possible to build it stock
and fly it on a 24mm E?
Thanks

This is what I've been advocating since the very first announcement of the SAT
V's return. Ever since I saw the first SAT V kit laaunched many years ago,( we
always wondered if the charge would fire in time to get the chute out and
opened), that there was a definate need to give this rocket a little more
altitude, and the AeroTech E15-4 I feel is the answer. You don't have to change
the mount oranything on the bird and get the altitude it needs. Hopefully this
will also provide a slow realistic lift off. I see so many people talking about
using  3 D's, 5 C 's and so forth and they are looking to have all kinds of
problems with CG/CP and ignition. I tend to follow the KISS principle. My first
launch will be on July 16th 1999 ( weather providing of course). Good luck on
yours.

There have been several recommendations within the many Saturn V threads that
have appeared on r.m.r. lately.   The opinion among several veteran rocketeers
is that an Aerotech E15, or E18 reloadable, is more reliable than a cluster of 3
or 5 Estes C motors.  The reason for this is that you have only one motor to
ignite instead of several.  It has also been mentioned that the Estes D12 is a
marginal motor for this kit, and an E is required to loft the model high enough
for its parachutes to fully deploy.  The D12 doesn't boost the model high enough
- if the delay was a second or two too long, the Saturn V kit may deploy too
close to the ground.  It may even hit the ground before ejection - an event many
here have witnessed.

You know, Wolf -- I would think, with all this 'hoopla' over the 'new
Saturns', that it shouldn't be too hard to talk Gary into '*** up'
a decent batch of E15-3 motors for everybody.  3 seconds is just about
perfect for this model (assuming some slight weight increase to beef it
up to handle the E).

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????

Someone at LUNAR flew a Saturn V (some time ago - not one of the new ones)
on an F39 (24mm) reload.  It was a very nice flight on that motor.

How many nonstandard SU motors are in a run?  If there are 2500 Saturns
out there, and half get built (the others in storage for auctions,
etc....)  And they get flown two or three times each, and half of those
are on Es, and the motor costs $8, someone oughta be able to gross $15K or
so.

Of course, if they make a short delay E15, there are lots of other things
to fly them in....

My opinions only.

(to the tune of "Happy Birthday")
Merry xmas to me,
Merry xmas to me!
`cause a brown UPS truck
Brought my Saturn to me!

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
one...)

Congrats on getting your Sat V. Don't know if they've even crossed the
border to here in Canada just yet, but I hoping!

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.

Write your Congressman.

Oops -- wrong thread.

Write Gary.

Isn't Estes in the buisiness to make money?  Maybe you should write to
Estes first, after all it is thier Saturn V kit.  The Aerotech E15-4
should be perfect, but there is always electronic delay and ejection
systems.

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 got a response from Gary (I cc'd him on the original response) -
and here's what he said:

Quote:

>    That would justify the NAR/Calif. certification and other costs.

500, huh?

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.

-- john.

(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.

are we sure that 3 seconds is the right time for a Saturn V on an E15?
