I Might be able to survive this, as I said I would paint the inside of the rocket body with epoxy, but I could also leave about 2 in of 20mm tube above the motor mount, and put a baffle in it, not a big one, but basically two, or even three, just over half moon heavy cardstock "plugs" just opposite each other about 1/4 in apart in the 20mm tube. |
