With the flat bottom plastic blades and some time spent making sure the heli is setup correctly I can maintain a pretty good hover in a 2ft square. This will never be stable like a CX but a little extra time with it goes a long way.

Centre the swashplate, get your blade tracking dead on and make sure the CG is right and you'll be in good shape. You can also crank up the gyro but you'll go through motors quickly. Keep in mind that any change in the throttle input will require the tail to keep up somehow and after a while you'll just start 'flying the tail'.

Good luck!
