i have one tip that helped me . one of things in a hover that is easy to do is over control watch the canopy area of the plane and not the tail this helps to keep you from over controlling. now the next tip is practice practice practice practice practice practice and more practice it took me 2 gallons of fuel of doing nothing but hovering. my ys 53 burns 1/2 oz per min. wide open it hovers at my plane at half throttle so you can imagine the time i have in hovering. there really is no trick to it it just takes time, and i dont think it takes a certain airplane either just one thats over powered. ive seen a j3 cub hover in the right hands and with the right motor sure certain airplanes are easier to hover.
just my .02 cents worth
