Hovering is simply a matter of pulling a plane verticle, and using power to keep it from climbing or falling, and using elevator, and rudder to keep the tail underneath the airplane. No big secrets to it. Having larger controls with lots of throw helps, as does an aft cg (not tailheavy) Just at the rearward part of the range. Of course you will need better than 1 to 1 power to weight ratio as well. Now go out, and practice and have fun.
