What kind of controller are you using, and have you calibrated it in AH?
Scaling lets you adjust the sensitivity of your controls along each axis. It is different for everyone but usually the sliders are set so that they are lower in the beginning and increase as the deflection moves out.
If you would like we could meet up in the TA one of these days and I can try to help you work through your issue. Just send me a PM if you're interested and we can set up a day and time.
