Fly a 24mm Engine in Model with a 29mm Mount
Aerobee 100 Junior Model Rocket Kit (29mm)
Currently very limited quantities
The Aerobee 100, or Aerobee Junior, was first flown early in 1958. This vehicle was designed by Aerojet General to be an inexpensive rocket to fly payloads of 50 - 100 pounds up to 90 miles. Most of the 20 produced used a solid-fuel booster, but two were actually sea-launched as a single-stage rocket (which makes this model eligible for NAR Scale competition).
Aerobee rockets have long been a favorite of scale modelers. This new kit is 1.89" in diameter and about 2 1/2 feet tall and features thru-the-wall laser-cut plywood fins (with optional balsa laminations), big balsa nose cone, pre-rounded basswood conduits, steel cable shock cord mount and water slide decal.
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 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.
