RE: combat submarines
Just as long as your no where near the combat club I battle with when your showing off your missle thingy, or any one else for that matter.
Some thing you might want to check out, we airplane guys can not put rc bb guns on our planes. the AMA & FAA specifically prohibit any thing other than invisible lasers or ultra sonic "weapons". your bb's in a missle might be prohibited. Check it out before a real "test" sends you to jail.
