Flat Pitch Curve - Please share

[KarbonBird]

There has been some discussion on a "flat" pitch curve around hover for a smooth AP heli.

Anyone got a good 5 pointer for a TR-600 to get me started?

Why not set your RPM where you want it to be, then set the third point on the pitch curve to where it will hover. Once done with that, try setting point two 10% lower than point 3 and point four 10% higher than point three.
This has worked for me on other helis anyway. After that it should just be fine tuning point 2 and 4 to your preference.
