RE: blade 400 pitch curves
IMO, you really shouldn't alter the pitch settings.
Use 40-45-50-75-100 Normal, 0-25-50-75-100 Idle-up or something very, very close.
I would also leave the throttle curves as stock or higher.
I use 0-50-80-90-100 for Normal (Finless' recommended curve) and 100-90-80-90-100 for Idle-up.
If you want to make the heli less sensitive reduce Dual Rates, add Expo or reduce the values in the Swash Mix menu.
