You must have misunderstood me. You don't have to master inverted to loop and roll. I have only begun to learn inverted hovering, I can hold it for about 10 seconds or so, but have been looping, rolling, and flipping for about 6 or 7 weeks now. If you never get disoriented right side up just go for it. Get into some fast forward flight at least 50' high and pull back on the right stick and pretend your are flying your sim.
