How to Hover
One of the best tips I got when i was learning was to fly alot of vertical uplines, using rudder and elevator to keep the plane flying vertical. Dont try to hover strait away because you wont learn anything if you are just practising the same bad habbits. Flying the vertical uplines will teach you the right sort of control movements. If your committed you can learn in a day, just slowly over a number of flights fly the verticals with less and less power, the plane will wander more and your controls will get bigger and bigger. Make sure you have a quite rearward CG too (40-50 %). It took me one day with this technique (8 flights). Its not hard once you know the process.
Hope this helps, just get out there and learn your plane.
