I've successful done aerial video and photography using both airplanes and helicopters. I also give flight instruction on both.
I've trained many to hover a heli within couple of hours and within a month they were doing 3D manuvuers.
I could probably train you to hover well enough in a week to be able to go into business doing RC aerial photography right away. I could almost guarantee that on both fixed wing airplane and heli. You don't even need a heli as I train on my heli. Haven't lost one yet.

Take care,
CCR
