    Two Stage Rocket Question.

    OK that’s what I thought should happen with the boosters. Thank you for the Responses. I will be using smaller engines in the second booster and the sustainer

    Two Stage Rocket Question.

    I am also building a multi stage, specifically the Comanche 3. It uses couplers to line up the boosters and sustainer. How tight should they fit together? Obviously you do not tape the stages together as the flame would not reach the tape through the couplers.

    Rocketarium Black Brant IVb Mod1

    We carry the air protectors in the back of the car wherever we go just in case. I took her to a monster truck show last summer the day after my wife decided to clean out the car. We saw one monster truck and then an angry dad went home.

    She is not a big fan of loud noises. The first time she launched I did not tell her there would be noise. I am just glad she still gets excited to go do stuff with me.
