First thing you will want to do is set 0º pitch at mid stick with a linear pitch curve. Then, you will want the same pitch positive and negative (for example, 13º positive and 13º negative). If you have more positive than negative, your swash plate is too high and you should shorten the 3 servo links, reset mid stick to 0º and try it again. If you have more negative than positive, then your swash plate is too low and you need to extend teh 3 servo rods and repeat the mid stick setup.
Make sure at mid stick that your servo arms are perfectly 90º to the linkage rods. This is imperative. Once you set your servos to 90º, you will never touch them again.
Once you have all of that, then set your pitch curve to 46 48 50 75 100. This will give you about -2º of pitch at low stick, 0º at mid stick and full pitch (whatever you set it to) at full stick.
