This is such an easy question to answer in Realflight as in real life your heli always rolls to the left (rotational torque effect). So your heli blades are going to have to be tilted to the right a few degrees in order to keep the heli in a stable hover. The same is true in full scale the difference is they build the main mast at a few degree offset so that the helis fuse appears to be perpendicular to the ground in a stable hover. The main mast of a model is not offset so your fuse will be tilted to the right.[sm=tired.gif]

So set your Realfight to all system default and consider this during hover as you take off you will need to put in slight right cyclic or roll (on the right stick).this will make the whole experience much more pleasant.
