To do that stuff with a .46 you will need a .25 size airplane. and that is not a beginners maneuver by any means

I would have to reccomend hours of sim time and get yourself SOME foamys

www.chargerrc.com has a good selection.

Another note. the top 3D pilots don't have to think about controls when they are flying all they do is react.
I started doing 3D maneuvers with my foamy about 6mos ago and it isn't easy. Eveytime I stop and think
what control to input the plane falls out of the maneuver and because it's stalled it's usually heading downward fast.
Sims don't model real 3D flying at all. all they can teach you is orientation.
