Aerobee 300 Model Rocket Kit (29mm)


Price: $74.95 each


Currently very limited quantities

The Aerobee 300, or "Spaerobee", was first flown in 1958. Eleven were flown by the Air Force and Navy with the last taking flight in 1965. The Aerobee series of rockets was designed by Aerojet General and is considered a descendant of the WAC Corporal.

Aerobee rockets have long been a favorite of scale modelers, and the Aerobee 300 has been an especially popular prototype. This new kit is 1.89" in diameter and over three feet tall! The kit features thru-the-wall laser-cut plywood fins (with optional balsa laminations), balsa nose cone and transition, pre-rounded basswood conduits, steel cable shock cord mount and water slide and self-adhesive decals.

Makes a great intro to mid-power rocketry and flies fantastic (and high!) on 29mm F and G engines! This model can reach some impressive altitudes, especially with G engines, so you might consider the Jolly Logic Chute Release as a good add-on to this kit if you plan on using the higher-impulse engines. The kit has an accurate scale outline but is also a fairly easy build that leaves room for the modeler to add additional details if desired.
