I am currently building a 2 stage 5.5" Nike Hercules. This rocket build has been a real challenge. I am a little concerned about my interstage coupling design. The two stages will connect with 4 - 5/16" carbon fiber rods mounted to the booster that will be inserted into aluminum tubing in the upper stage. The 4 carbon tubes have a bit of flex to them. My question is: Just how solid does this connection have to be. I am thinking it should be rock solid as to not allow any flex between the booster and sustainer.
