Quick guide to use: Use it as inferno VTOL as a temporary way to adjust angle. Yj83 is a supersonic anti-ship missile which was designed 20 years ago in China. This is a project to challenge my XML ability. "Auto"means you don't need to do anything except to press"lunch weapon"button, and then the missile will drop two launcher covers, unfold its wings, fire the booster and drop it exactly 5 seconds later, and of course fly straight to the target. Check how it works without the need of human control by downloading. Wish you have a good time and find all the secrets in the missile. *Tips: *The missile is so complex that the booster is not very stable(which makes its speed lower than the real one so that I can use smaller thrust) so please avoid firing the missile in the launcher at more than 80mph. Disable the collision of the launcher or remove the booster help it become safer, but it will looks a little strange while launching :-)
