[WANTED] Estes ARCAS (K-26) Info
Working on a sim of the ARCAS, and I've got a conundrum... JimZ's scan of the instructions clearly states that the kit uses a JC-55C. The Estes 1971 catalog gives it as 1.3". OR's default gives it as 1.25", and Semroc says that a JC-55C is 1".
When it comes to this kit (the K-26) which spec is correct?
Also need to know more about the fins... Those shapes are pretty complex, and if I can get the length of the fin support pattern, I should be able to scale both fin shapes based on that.
Thanks!
Jim
