I am in the process of listing all the parts I need for my next rocket before I buy them all. I am turning a 6" dia. 36" tall crayon bank I have had for a while into a rocket. Anyways, I want to use rail buttons for this project and was wondering the difference between small and large rail buttons. Would I be better off using large ones because of the dia. of the rocket?
