Whats the name of the maneuver often performed by Airwolf or a model of the helicopter?
I think you might be referring to a torque-turn, also called a hammerhead, it’s when you fly straight and level with some speed and then start going nose up to where you are nearly vertical. Just before you lose upwards momentum, you kick one of the pedal and yaw 180 degrees to the left or right and you descend nose first and then level out again. It is a trick and doesn’t really have much real-world purpose, but it’s fun to do. I’ve seen Airwolf but I’m not really sure if this is the trick you’re asking about, I don’t really remember them doing it too often on the show, but then again I haven’t seen it in quite awhile.
