I have a Magnum XL.70FS powered U-Can-Do 3D (46 size). I'm happy with the way it flies, but I've been entertaining the idea of perhaps installing one or more gyros to help me learn some of the so-called 3D maneuvers. I'm thinking of a gyro on at least the rudder and perhaps the elevator. Would this help with hover, or work at all? What would be a good gyro choice?

Thanks,
