I've spent many many hours on sims and at the field working on this and I think one thing that helped it click for me was concentrating on one of the four stick movements...

I mean watch the plane rolling and go through the stick movements and always reset the timing in your head when the top of the wing crosses that threshhold where you switch and put in elevator up. (You will invariably get the timing off at some point around the 1 revolution mark while learning. If you dont "reset" the timing of stick movements, then it gets totally wrong within a revolution or so to where you're steering it into the ground instead of holding the nose up.)

Then go through the other motions and reset again when the wing is coming up again... if you don't have some reset point in mind on every revolution to help with turning or maintaining that nose up attitude its just impossible to keep up with timing EVERY motion, its just too fast. You WILL get behind or ahead, so concentrate on one, then make the others smoother later when you're able to keep up... if that all makes sense.

BTW, I do the four independant motions like that video out there someone did on Real Flight G2... not like the Flying Cirkus one where they move both sticks at the same time... since I learned one way seems weird to join both movements but maybe its easier and it still looks good...
