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!
