My friend Tim built this Estes kit, Catalog number 1343 back in 1980. He gave it to me, when he was cleaning up around the house, some 40 yeas later to fly it for the first time. My only repair was that I replaced the elastic shock cord with Kevlar. The rocket flies great. The first flight was with and A8-3 and then I went to a C6-5. The original chute, he had in there, worked perfectly also. The model came in a combo pack with the Orion Starfighter.
