Keep in mind that I own the fixed pitch Honey Bee, but this applies to most helis. For starters, an effort should be made to balance spinning parts, such as the tail rotor. As far as the tail goes, if your heli uses an All-N-One Receiver, Esc, and Gyro, it will typically have a couple of small adjustment trim pots on it. One of these usually adjusts the main rotor to tail rotor mixing ratio(Torque Cancellation)or revo-mixing, and another one to adjust the gyro's gain. If your heli(assuming clockwise(as viewed from the top of rotor) main rotor rotation) seems to go nose left when you apply throttle, and may also go nose right when you reduce throttle, you may need to increase the "proportional" a.k.a. main to tail mixing(revo mixing). If the opposite is true, you may need to reduce it. If the tail is rapidly jerking back and forth(gyro hunting) at hover(steady throttle position), then you may need to reduce the Gyro's "Gain" pot. If the tail seems to wander more slowly(Drift) at steady throttle, you may need to increase the Gyro's gain pot. This stuff should be covered in your heli's manual, and you should consult that to make sure. Keep in mind that these little E-Sky helis don't typically have Locking(Heading Hold) Gyros, and some rudder stick is almost always required to keep the nose pointed where you want it. One rule of thumb I go by is, if the trim lever on the transmitter corrects the tail problem, the you concentrate on the Mixing "proportional" pot, if it does not, you concentrate on the Gyro's "gain" pot. Hope that helps. Good Luck!.
BTW, if your heli uses a seperate receiver, ESC, and external gyro, then revo mixing is usually adjusted on the transmitter, and the gyro will have it's own adjustments on the gyro or gyro's control module. Keep in mind with all of this, that most gyros are temperature sensitive, so it is a good idea to let the helicopter sit in the flying environment for a few minutes. For example, if you make the adjustments in an air conditioned living room, and then take the heli outside on an 85 degree day, and fly right away, you may find that your adjustments are all off. If you let the heli "get used to" the outdoor temp before powering up, you will probably find that your adjustments are OK.
