This fin uniit can be used for either
Early Langley Capsule Set,or
Late LJ-5B Flight Capsule Set. You will have all the nozzles and even fin bracket detailing as accurately depicted as the full scale version! With the combination of these three components you can make a quick, yet sharp looking Little Joe. This fin unit is BT-70 based scale. Alternatively, this unit also works well with my
transition adapter for use of the Estes Capsule set sold with the kit. The choices abound!
