It must have been great fun to fly Hueys, but the object behind flying such machines must have dampened your spirit at times. I write software which reads flight data recorders so I know a little about a/c, but not so much about helicopters. Too difficult to predict!
It was great fun. Didn't like getting shot at, but that came with the job.
When Leonardo DaVincie invented the helicopter, he then decided there was no way it can fly. Take gyroscopic precession. If you exert a downward force on the front of the rotor disk, the aircraft will tilt toward the left (90 degrees in the plane of rotation). So, all the controls are set up to exert their force 90 degrees ahead of the plane of rotation. In a fixed wing aircraft, if you go too slow the airfoil will stall causing you to lose lift. In a helicopter, if you go too fast, the rearward rotor blade will stall, and you will crash and burn.
