RE: Simple rule for head-in hovering
When I learned, I basically tilted the stick in the direction of the tilt of the head. For instance, if the helicopter's main rotors were tilted foward, i would tilt my cyclic back. This way, it balanced out. I did read some things about how this isn't a good way to learn because its not proper etc... and you won't learn to do it for real, but in a couple weeks, this carried over and I was able to fly nose in without thinking about the tilt of the main rotors.
