yeah basic 3d on the sim is not the same as basic 3d in real life , at lest not in my experiance. mostly its a question of power to weight , and setup. in the sim setups seem to be perfect, in real life most heils tend to have quirks left to be ironed out. and the power of most the models I have used in real flight g3.5 seem to have more usuable power than in real life.
