Last time I messed with sims I tweaked the models weight and power to get the feel and response closer to what I remember it being like. Add more weight and take away power until you can feel like the model is "heavy" on the sticks. This will teach you some delayed response and anticipation from the model.
Next play with wind and weather settings and try to land in adverse conditions. The worse it gets the better it will teach you until your tested in real life RC flying.

My take on the sims was the models feel too light responsive for what their supposed to be.

Oh and edit a model then save it as a separate plane with a new name so you can have several modified planes to test and compare.
