Digging thru my kits / parts box, I found an open Estes Nike-Apache kit #1957. All the important parts (NC, transition, balsa marked for fins) and instructions are in the bag, along with the pretty color insert panel, but NO BODY TUBES. Who knows where they went ... after all, this is only a kit from the 1980's! I've looked everywhere I can think of to find the length of the original BT-5 and BT-55 tubes that came with the semi-scale kit. I suppose that I can guess based upon scale data supplied, but I'm hoping someone has one of these in their rocket fleet and would be so kind as to measure the body tubes. I would very grateful. Thank you!!!
