First off, I am having a great time learning the sabre! I can start it up, take off, navigate and land. I have just started learning to use the weapon systems. I am having a problem with firing the gar 8. I have missile selected, mechanical sight uncaged, elec. cage button held down until in firing position, I release the elec. cage, I get full tone and I press and hold the weapon release button, and nothing happens. I just go flying past my target. I don't know what I'm doing wrong. Any ideas will help!
