The MicroBeacon helps you find your model in the tall grass! Requires 12v battery, MBB-12.

Note on shipping Microbeacons: Any order with one or two Microbeacons and/or MB Batteries will go out First Class Mail in a padded envelope, at a total shipping/handling of $3.00. Ignore the shipping cost on the shopping cart, which defaults to Priority Mail.This web site does NOT charge your credit card when you order; you will get a correct invoice by email when I process the order, and your card will be charged just before the order ships.

The SEC-5B Ejection Canisters feature a snap-top ejection charge container that holds 1.5 grams of black powder or smokeless powder. The single-use Ejection Canisters are convenient and reliable methods of deploying your recovery system.

XLEjection Canisters are for rockets with more volume to pressurize than can be done by our smaller canisters. Each Ejection Canister is tested for continuity before being packaged. Variable capacity allows you to determine how much propellant you wish to use for your particular recovery system.

The famous "As a Matter of Fact, I AM A Rocket Scientist" T-shirts! High quality 50/50 cotton/synthetic shirts, screen printed with our tasteful logo.

The Crablight is...well, it's a weird little pocket LED light with two independently adjustable lights. Not really sure what it's good for, but it's cute and lasts a long time. The battery is the same one used in our Microbeacon and PIT. Options include a Velcro pad and a magnet base.

Rocket Glue is the very best glue we've ever found for building model rockets in classrooms. Non-toxic and harmless, works on plastic, and fast grab. Available in 1 ounce bottles, three-packs of small bottles, and 4-ounce refills.

3-pack of 1 oz bottles of Rocket Glue, easier to share in a classroom rocket building session.

Test your igniters and ejection charges before launch to make sure they'll work! The Pocket Igniter Tester sounds a tone when it detects a complete circuit. Safe for use with low-current igniters (electric matches). Battery not included.

Gunzilla is a one-step cleaner that is perfect for reloadable rocket motor casings. It cleans, lubricates and protects metal parts, and dissolves residues from rocket propellant and ejection charges. 5 ounce wide mouth bottle.

Compact Ejection Canisters are designed for smaller models that use electronic ejection, but have a diameter that is too small for our SEC-5 Standard canisters. They are slim enough to fit into 13mm body tubes. CEC-5 canisters come packaged in tamper-proof ziplock bags of 5.

Large Ejection Canisters are about half again as big as the standard SEC-5a Ejection Canisters. They hold about 2.5 grams of black powder (not included). They are suitable for rockets of 4 to 5.5 inches in diameter. Each Canister has the resistance written on the side, so you can test it before use.
