simply install addon 3&4, since there's the edge 540, the extras in them already setup for 3-D. The only way i learned was by spending hours infront of the thing. Another easy way to learn hovering is to take the plane up about 50ft n press f11. After that, hover the plane infront of urself, it'll be alot easier. N dont forget to reduce the time multiplier to around 60%.

The basic thing in 3-D is corrections in the planes movements to keep it doing what it is meant to. Timing for these corrections is key and can only be developed with expereince. So, i suggest u get down to it immediately!
