I am planning on designing and building a 2 stage rocket that uses gap staging. I have several Semroc heavy duty 1.15 inch outer diameter tubing with 4 sets of slots for fins. The tubes are 22 inches long. Obviously the booster tube will need to be cut down, but what is a good length?
I have G. Harry Stine's book and know that 12 inches will work fine, but I don't need that much. I am thinking maybe 8 inches. Now is that 8 inches between the top of the booster motor and bottom of the upper stage or 8 inches for the overall booster length? Any recommendations?
