I learnt all 3D on a Sim 1st and the when I could do it on there started trying with a plane.

The think I discovered is just try and learn one thing at a time and keep doing it again and again until you perfect it rather than trying a number of different things in a row.

I had a knee operation and was laid up in hospital afterwards and spent 3 hrs with nothing else to do so just kept doing rolling circles until I'd perfected them. That then gives the natural sticking which is the same but bigger inputs to try rolling harrier circles.
Again I couldn't hover so just sat with the Sim for hours doing it again and again, now I'm fine if I start with canopy towards me and fine if I start with gear towards me but's it's not natural to go from one to another like torque rolls, if I hold it gear towards me for a while and then turn I'll forget which way it is and still go opposite to correct so now whenever I pick it up I just sit and do torque rolls and having started that 3 days ago I can already see an improvement.

You've then got to translate it into your plane but it's brilliant to get things natural and for learning sticking so you don't have to think about it !!
