This little rocket caught my eye today. Reminds me of the much later "Estes Comet Chaser" which I've built, and upscaled as a "Teacher Scale".
However the instructions found on oldrocketplans.com and plans.rocketshoppe.com lacks a reference to the dimensions of the fins (except that they are 3/32" thick (and you make 4 of them)), and the decals have no reference to their dimensions. Sure, it's a .pdf, and that SHOULD lock the scale... BUT... I'm in China, and .pdf files don't print at that scale (it seems to be somewhere around 15/16" to the inch)
