Giant Leap Motor Retention
The new SLIMLINE motor
retainer:
It works on a similar principle to the Aeropac retainer, but features a
retaining ring that goes INSIDE the sleeve. The creates several advantages. It
reduces the machining 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 have a spacer ring to accommodate KOSDON, Ellis Mountain,
and Hybrid motors too!
The matching SLIMLINE adapters are due out very soon. Like the retainers, these
will be black anodized aircraft-grade aluminum (6061-T6). The adapters will nest
inside existing SLIMLINES, but have their own retainers built-in. Finally, a
fully integrated system . Available for29-38mm and 38-54mm conversions.
|
HOW TO INSTALL AND USE THE
SLIMLINE: |
|
|
When assembling your rocket, be sure to leave1/2" 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. |
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!

The Best of Both Worlds
...and then some.
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.
Once you get an extraction tool
and a threaded ring (closure) in a given size, all you need for additional
rockets are bases (retainers). Starter Packs:
.....includes one base, threaded ring, and a tool. After that all you need for
the rest of you rockets (in any motor size) is another base.
29mm...$41.95
38mm...$45.95
54mm...$46.95
75mm...$51.75
98mm...$54.50
Giant Leap Rocketry introduces a
new retainer that's shaped like a nozzle! The aft 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.
Works
with CTI Pro 38 Motors! System
includes base, tool, threaded ring (same ring and tool as used on plain
threaded system). If you already have a ring and tool, all you need is a base
for each rocket.

Slimline Tail
cone Retainers
So Beautiful, So Simple
|
Slimline Tail cone Retainers give you a sleek, low drag look. As with all Slimline Retainers, the motor is inserted into the motor tube and then secured with a circle ring. |
A great way to finish the aft end of a rocket. |
|
Your motor tube is glued to the machined grooves inside the tail cone. Use JB Weld or other heat-resistant epoxy. Will accept Slimline Motor Adapters, too! |
The inside is machined hollow to reduce weight.
