I've been flying for about 1 year now and can now fly all orientation except for inverted flight (thats next). I never really thought about it until recently when I saw some Youtube video on 3D flying. I notice people can piro left/right very quickly.

I'm flying a Century Swift, Century Raven 50SE, and a Century Hawk pro upgraded to the 50.

When I move rudder stick to Left - all 3 heli will whip to the left quickly (still not as fast as those in the video). When I move the rudder stick to the right - the heli will sluggishly turn to the right. Because I'm not doing any 3D or any advanced flying I have the head speed relatively low. not sure how fast the blades are spinning but at 6deg pitch it is barely hovering. If I increase my had speed obviously the tail will turn that much times faster and I should have a better response.

is the solution is to increase head speed? How would I know if I'm over reving withought a governor? I've upgraded to the metal rotor head so i'm not too worried about blades flying off. Or, maybe it's in my setup?

Head speed is a key but it will always be faster to the right beacasue of the main blade rotation.

You can use your rudder ATVs to get a faster or slower piro rate. Increase the slow sides ATVs to more than 100 and it will piro much faster.

On a heli with main blades rotating clockwise, the piro rate to the left (nose left/tail right) will tend to be a little quicker because the heli will be rotating with the torque. You can adjust the left and right piro rates independently, as has been stated, by adjusting the rudder ATV's. You should be able to able to get the left and right piro rates to be equal. Some gyros, like the Solid-G for example, have a piro balance setting which can be used also to achieve the same thing.
