29mm 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.

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.

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.

PROPELLANT STYLES

Firestarter (amber), Whitestar (silver), Standard (brown), Fast (orange), Buttkicker (black)

Packaging of 29mm reload kits

3 flight loads to a typical package.
Includes 3 liners, 3 sets of propellant grains, a single nozzle to
be reused, and instructions. Kits specifying a delay come with the
delay pre-cut and in some markets a small package of black powder
for the ejection charge. If black powder does not come in your kits
in your market, it is available from any gun shop with no permit and
you should select 3F or 4F grain size. The instructions specify
quantity but generally 1/3 to 2/3 of one gram is all that is needed
for model rockets up to 4 inch diameter by 3 foot section. Delays
are always free for related propellant purchases and even if you buy
a kit without a delay and want to add one we or our dealer will
cheerfully provide you with delay either pre-cut or a stick you can
cut to length as needed for the load selection, rocket weight and
weather conditions. See our tips and tricks website or instructions
for delay selection and modification. Delays are VERY dimension
sensitive. Exact cut lengths are critical. 1/32 of one inch is a full
second of delay time.
