[Skidz]

Doing Immelmanns and half cubans on the sim will allow you to keep the aircraft in a single vertical plane using elevator and aileron to "turn" the aircraft around. In other words you know where the aircraft must be as you haven't actually turned it but rather flipped it over. Doing banked turns will bring the aircraft around in to a whole new spot in the 3D world of the simulator from which depth perception and orientation problems may arise. Eventually you will trust your instincts (which takes practice) such that you know what and where the aircraft is going even if you cant see it clearly. From there your instincts tell you what your thumbs need to do to turn the aircraft back toward yourself.

In real life, Immelmanns and half cubans are immensely more problematic than a banked turn if you fly too close to directly over your head as your aircraft is aimed/flying at you, left and right are reversed, and... an accidental turn in to the pit/spectator area will result in a flight line incursion at a flying field and a visit from the air boss who wont be happy.

What the sim doesn't do well is create that sense of shitting ones pants when a turn gets ugly and obstacles are reaching out to tear apart your aircraft and finances.

Force yourself to learn coordinated turns (aileron plus a bit of rudder simultaneously). If the plane gets away from you on the sim, trust me, it will in real life too. Also, add a bit of a breeze (easy does it) as the plane needs to drift slightly to prepare you for the "real McCoy" (what a pun folks!).
