Helicopter's Advance Flight Model Analogue Collective with Regular Gamepad

[Yonif 0]

Is there any way to perfectly control the helicopter's advanced flight model with just a gamepad? Right now I'm using the regular gamepad Logitech F310. I bind the collective (analogue) to my right controller stick. The problem is because the collective acting as a lever, when I'm not touching the right thumb controller, the collective stays at 50% power, making it impossible to perfectly hover and trying to land smoothly. To be able to do collective raise I must holding up the controller, as well as collective lower with holding down the controller. Is there any way to fix this in order to achieve smooth control over the collective?

I don't know what the correct term that I'm looking for is, full axis control maybe? Because I think my state of gamepad's stick for the collective is two axis.
