Contributed by Lance Alligood

AeroTech H123W-M HPR reload

The AeroTech H123W-M is a high power rocket motor reload. This is arguably the most popular reload used for certifying Level 1 with because of its general easy availability, low cost, and that so many rockets perform well with this particular motor. You must be Level 1 certified (as recognized by NAR, Tripoli, and/or CAR) to purchase and use one of these reloads.

New rocketeer who attended TORC 703's January launch day and bought a few kits to assemble.  Have been learning by doing.

Hard to socialize with other rocket-boys here in SE Ohio... but perhaps I'll get to meet a few at a launch day soon...are there any club launches nearby soon?!

Shella Condino now has a “Green Card” and continues to inspire her students in Presidio, Texas. Earlier this year, she once again, lead a team of kids to the Team America Rocketry Challenge finals. The team finished fourth over all in the ...

Model Rocket Building: Quest Aurora Build, Part 1, Parts
This catalog page is from the 1992 Quest Catalog. The Aurora was Quest kit #3002, a parasite boost glider. The model is 15" tall built around a sturdy 25mm Quest body tube. The face card description says: "The boost glider is modeled after the new, top-secret successor to the SR-71 spy plane. Glider jettisons booster at 500 feet and glides back to earth while booster returns via 12 inch parachute." I bought this one a few months back at the Orlando Hobby Spot store. They have a very limited rocketry selection but occasionally you can find an interesting older kit. The kit was marked ...
