24mm RELOADABLE MOTORS
Aluminum reloadable housings. Propellant cartridges
to fit for multiple reuse. Increased labor but lower
cost than expendables. Only standard coreburning grain
geometry type motor loads available.

The system.


U.S. Rockets R&R Reloadable motor system with casing, closures, propellant,
delay, thermal liner, and nozzle. The rear closure has an integral thrust
ring and the forward closure can be plugged or have a user modifiable delay.
Reusable closures and expendable propellant reloads. 240 N-s power systems
are the largest FAA exempt motors, being under 125 grams propellant.

Our system has fewer parts than other brand systems, fewer leak points, uses
less grease, is more suitable for assembly in cold weather or for folks with
fat fingers or gloves on, and allows reuse of the nozzle in many instances.
Users who save superior quality used U.S. Rockets brand nozzles, repurpose
them for use with our "propellant bulk packs".

First purchase CLOSURE SET includes nozzle holder end
closure, delay holder end closure, liner ejector dowel, spare
o-rings, instructions. All other parts are separate components
for replacement or special applications. Nozzle closure has
positive seal in two places and recommended nozzle (included
in reload packs) is reuseable at least three times. Bulkhead
closure has positive seal in one place and standard friction fit
delay element. Closure accepts small quantities of ejection
powder in the well and 1/4g to 3/8g is recommended for MR and
LMR respectively. Liner ejection tool aids removal of paper
liners which have been damaged by long duration propellant
loads thus protecting the valuable casing system. Extra o-rings
are included for replacement as they become damaged during
normal usage. In particular the nozzle o-ring can be damaged
by installation of nozzles so bevel the nozzle edge slightly
with sandpaper to increase seal life.

Testimonials and Product usage
U.S. Rockets Reloadables

There were two Vaughn Brothers Extreme 24s and an Extreme 29. The Extreme 29 was powered by one of Jerry Irvine's G280-10s. Holy Cow.... do those buggers move. I thought G125s were hot. G280s are hotter than 40 yards of hell. They actually scream. Another G280 was used in a LOC Little Nuke. I'd like to plug LOC. The Lil Nuke is an outstanding rocket. Easy to build, streamer recovered and it flies like a home-sick angel.
- R J Talley


Sure I do! I flew a USR F100 a couple of months ago. Outrageous motor! I have a couple of G120's in my storage too. Don't know if I have the guts to fly them though! :-)
