This is my challange about shooting on a small helicopter, you will fly this to destroy the terget (in air)on the ground nearby.There are nine (should bee called "bullets"?) aviliable. Use detcher 1~3 to fire them. Actually, it is not really easy to hit, for driving a chopper is far more difficult than a simple aeroplane.How to drive a helicopter: like other simulators or games, pitch to move foward or back, roll to move left or right, other specifictions are similar to an aeroplane.My idea and terget is from @thomasjaf, and his challange http://www.simpleplanes.com/a/1Fwk8s/Rocket-launching-practiceAlso, remember to rate! ThanksHave fun:_)
