jeang, amen on the practice. Sure CG, power, throws, and even type of plane all play a big part. However, people tend to want a secret technique or plane that makes hovering really easy. (The Spad 3d is probably the easiest) The main ingredient is alway practice. A young pilot told me his Magic wouldn't hover like mine does. I said I bet his could hover and preceeded to hover it easily. I talked him afterwords and offered some tips, but the biggest tip was practice. Within 2 weeks, he was hovering all around the field. I asked him what helped him master it and it was practice. I think it is "the touch" or "instinct" you pick up with practice.
