I practiced loops and rolls om FMS as well before I went out. It's good to get your fingers co-ordination right on the sim.
I fust finished my 4 packs worth and I found my nicest rolls were when I didn't add any negative pitch at all, just got some good speed up, plenty height, then just pulled bachk on the stick and held it there. Maybe a touch more cyclic as you come around, but I left the throttle stick alone.
With rolls you gotta get the timing of the negative input just right, then it's actually a roll. Time that a little off and it looks like a corkscrew and you loose more height.I got it wrong this morning. I rolled my rex into the ground bent the feathering shaft, main shaft, broken blades. broken main gear. The usual stuff that breaks! Got plenty of spares so I was up and flying again after lunch.
I think if you can do them on FMS then you're ready to go.
