Actually, the TLP Nike Hercules plan pack is for a two stage rocket with a four engine cluster in the first stage. The distance between the first and second stages precludes gap staging for the second stage, so it will have to be ignited electronically. Quite a challenge even for experienced builders. I wound up buying the single stage kit instead. Apogee has a plan pack for a smaller Nike Hercules, 4 engine mini motor cluster with option to build as a single or two stage model. Fin and transitions templates included, as well as a parts list and informal instructions. Almost as good as a pre-packaged kit:

As mentioned by others, finding a kit would be difficult, and even then it might sell at a collector's price. Good luck.
