38mm RELOADABLE MOTORS
Aluminum reloadable casings. Propellant cartridges
to fit for multiple reuse. Increased labor but lower
cost than expendables. Only standard coreburning grain
geometry type motor loads available.
38mm assortment with 120, 240, 480 cases and a closure to share.
Shows propellant, nozzles, delay, liners and closure o-rings.
Most common now are white paper liners and blue closures.
38mm 480 reload kit. It's simple. Propellant, nozzle, delay, delay o-ring, and liner.
You put a little grease on the OD of the delay and on the little o-ring.
Most common now are white propellant casting and thermal liners.
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 are compatible with the "other" brand
casings in the market. 240 N-s power systems are the largest
FAA exempt motors, being under 125 grams propellant.
Our system has fewer parts, 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, 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 two places and standard friction fit delay element with expendable o-ring seal. Closure accepts small quantities of ejection powder in the well and 1/4g to 3/8g is recommended for MR and LMR respectively. 1/2g is recommended for typical HPR rockets. Liner ejection tool (wood dowel) 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. Grain count is nominal. Longer motors use fewer double length grains (6 grain 720 uses 3 double length grains). | |||

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. Delay needs to be a tight (interference) fit. If loose add a FLAT layer of clear tape to the outside surface until it is a tight fit. Closure edge is slightly beveled to allow insertion and the delay should be a clean smooth edge. Debur the end circumference as needed by rubbing on a smooth surface such as glass. | ||

Try one of the more innovative and exciting motor systems around.
A 38mm 240 case and associated Standard load produces almost 20
pounds of thrust for almost 2.7 seconds. You can get a case system
and four loads for around $90 + $96 MSRP. This is an FAA exempt
propellant weight. About 25 bucks a flight and suitable for small
fields with a 4 inch rocket. The 240 N-s power H89 for $25 ($0.104/N-s)
compares favorably with the $5 Estes 27 N-s E9 ($0.185/ N-s).
A 38mm 480 case and associated Standard load produces almost 40
pounds of thrust for almost 2.7 seconds. You can get a case system
and four loads for around $90 + $194 MSRP. Use in a 3 or 4 inch rocket.
A 38mm 960 case and associated Whitestar load produces almost 72
pounds of thrust for almost 3 seconds. You can get a case system
and two loads for around $100 + $194 MSRP. Use in a 3, 4, or 6 inch rocket.
A 38mm 1440 case and associated Whitestar load produces almost 108
pounds of thrust for almost 3 seconds. You can get a case system
and two loads for around $100 + $290 MSRP. Use in a 3, 4, or 6 inch rocket.
Motor systems up to 240 have under the FAA exempt propellant weight.
