mythsc281,

The tail rotor will spin after you apply 50% to 75% or more throttle. Tail rotor speed changes with left-right motion of the left stick, and it depends on how much throttle you apply for the tail rotor to start spinning.... at least on the Axe CP that's what I've noticed.

Under ideal conditions, the tail rotor should always spin, even before lifting up, so the heli would have a perfect lift up without spinning left or right, right from the moment it's still on the ground.

It only makes sense, don't take my word, since I'm not an enginner, just someone that uses common sense, and that has a strong background in Electronics and some handyman skills.

Imagine your heli lift up without any tail rotor speed, it would spin on its own axis like crazy. The tail rotor speed counteracts the main rotor, spinning faster or slower, moves the tail one direction or another... so in my humble opinon, under ideal conditions, the tail rotor should always spin, right from the moment the helicopter is taking off.

Adjusting the pots on the electronic board you should be able to have the tail start spinning even at low throttle settings, therefore having a more stable lift up without the tail spinning and the heli turning on its own axis at lift up time.

That's only my humble opinion, which doesn't necessarily means that's the way it is. ;-)
