It works on a similar
principle to the Aero
Pack retainer, but
features an easy-to-use
circle ring that snaps
into a groove on the
inside of the base (or
sleeve). The creates
several advantages. It
reduces the maching
costs, thereby
drastically lowering the
price. The
Slimline
also has less
aerodynamic drag
compared to other
retainers.
Slimlines
are designed and priced
great for everyday
rockets. For minimum
diameter and boat tails,
they are unmatched!
All
Slimlines
work with Aerotech and
Cesaroni motors, and
have a spacer ring to
accommodate Kosdon,
Ellis Mountain, and
Hybrid motors too!
The matching
Slimline
adapters are now
available. Like the
retainers, these are
black anodized
aircraft-grade aluminum
(6061-T6). The adapters
nest inside existing
Slimlines, and have
their own retainers
built-in. Finally, a
fully integrated system.
How strong is the
retaining ring in the
Slimline?
At LDRS 2002 in
Amarillo, a motor
catoed (blowed up
real good). As a result
of the explosion, the
motor casing was laid
flat....torn absolutely
wide open. But the
Slimline on the rocket
remained intact, and the
retainer ring never let
go. That's how strong a
Slimline is!!
How to install and use
the Slimline:
When assembling your
rocket, be sure to
leave 1/2" of motor
tube sticking out
the aft ring.
Glue on the
Slimline with a
strong heat
resistant adhesive
Insert motor
Snap the retaining
ring into the groove
by hand. Presto,
you're ready to Fly!!
You can remove the
retaining ring by
lifting one end out
of the groove with a
screw driver or pen
knife. Then simply
remove the ring by
hand. It's that
simple!
Slimlines are made to
fit standard industry
motors such as Aerotech
and Pro38, Pro54...,etc.
Once your Slimline is
set up to retain these
motors, they will retain
all standard high power
motors in that diameter.
However, this does not
apply to Kosdon and
Animal Works motors (AMW),
which unfortunately have
a different thrust ring
arrangement.
The
external thrust ring
on Kosdon and AMW is
wider than on all
other motors in high
power rocketry. The
external thrust ring
on these motors
overhangs the
motortube by a about
4 thousands of an
inch and will need
to be ground down
slightly in order to
make it fit. This is
possible and has
been done frequently
by our customers.
The
placement of the
thrust rings on
Kosdon and AMW
motors is also
nonstandard with all
other motors. The
distance between the
aft end of the motor
and the external
thrust ring is
longer than on all
other motors in high
power. So once the
Slimline is set up
for a Kosdon or AMW,
it will not retain
other motors.
No
Slimline adapters will
work with Kosdon or AMW
motors.

Slimline is the
new standard in motor
retention. The name
Slimline can be
found at almost every
launch site around the
world. The classic
Slimline uses the
well-known snap-in ring
to prevent the motor
from falling out. It's
an overwhelming success
and will remain an
important part of our
line. But some flyers
prefer a threaded-type
motor retainer. To
answer their call,
Slimline Motor
Retainers now come in a
threaded version but
with an important
improvement...
This avoids the extra
drag and added bulk of
motor retainers with
external rings. The
Threaded Ring is on
the inside! With the
ring threading on the
inside, the retainer
keeps it's sleek, simple
design, and it's low
cost. It lives up to the
name.......Slimline!!!
How does it work?
The Threaded Slimline is
comprised of three
things:
A base (or
retainer),
A threaded ring (or
closure), and
An extraction tool
(not completely
necessary, but makes
life simpler).
The base (retainer)
glues to your motortube
(you'll need about 1/2"
of motortube sticking
out). We recommend JB
Weld. Then insert
your motor and secure
with the ring (or
closure). That's it.
Works with Aerotech and
Cesaroni Motors!
Once you get an
extraction tool and a
threaded ring (closure)
in a given size, all you
need for additional
rockets are bases
(retainers).
Threaded Slimlines
are compatible with all
existing snapring
Slimline Adapters.
Soon to follow:
Threaded Slimlines
in larger diameters,
tailcones, and adapters.
Technical note on
Slimlines:
Slimlines are
made to fit standard
industry motors such as
Aerotech and Pro38,
Pro54...,etc. Once your
Slimline is set up to
retain these motors,
they will retain all
standard high power
motors in that diameter.
However, this does not
apply to Kosdon and
Animal Works motors (AMW),
which unfortunately have
a different thrust ring
arrangement.
The external thrust ring
on Kosdon and AMW is
wider than on all other
motors in high power
rocketry. The external
thrust ring on these
motors overhangs the
motortube by a about 4
thousands of an inch and
will need to be ground
down slightly in order
to make it fit. This is
possible and has been
done frequently by our
customers.
The placement of the
thrust rings on Kosdon
and AMW motors is also
nonstandard with all
other motors. The
distance between the aft
end of the motor and the
external thrust ring is
longer than on all other
motors in high power. So
once the Slimline is set
up for a Kosdon or AMW,
it will not retain other
motors.
Starter
Packs
includes:
One base
Threaded ring
Tool
After that all you need
for the rest of you
rockets (in any motor
size) is another base.
Remember, you don't need
to purchase a threaded
ring and extraction tool
for every rocket you own
of a given motor size.
If you have four rockets
with 38mm motor tubes,
you need four 38mm
bases, but only one or
two rings and a single
extraction tool.
No Slimline adapters
will work with Kosdon or
AMW motors.

end of your rocket will
look like the real
thing. It works exactly
like the standard
threaded Slimline,
except it adds realism
and beauty to the look
of your rocket. The
nozzle retainer adheres
to the motor tube just
like other Slimlines.
Now in Silver...or in

Installation is easy - -
there's a built-in stop
inside the retainer that
butts up against the
motor tube.
Just insert your motor
and thread down with
retaining ring...and go
fly. That it!!
Works with Cesaroni

Like the retainers,
Slimline Motor
Adapters are machined
from T-6061 aluminum.
The Slimline
Motor Adapters, when
used with the
Slimline Retainers,
produce a completely
integrated motor
retention system. The
38/29mm and 54/38mm
motor adapters work as
follows: Suppose you're
using a 38mm motor in a
rocket with a 54mm
motortube. Insert the
54-38mm Slimline
Motor Adapter into your
motortube and lock it in
place (as you would a
54mm motor) using the
54mm Slimline
Retainer already on your
rocket. Then insert the
38mm motor into the
Slimline Motor
Adapter and lock it into
place using the retainer
built into the adapter.
It's that simple!!
(the 75/54 and 98/75
adapters work a little
differently. See below)
Slimline adapters
come with clear
instructions. Can be
used with Aero Pack
retainers too!
Slimline adapters
are Long! Can easily
handle J570 easy access
motors. Assemble with JB
Weld.
How it works:
Insert adapter into
rocket that is
pre-equipped with a
Slimline

Lock it in place

Lock motor in place
