Since I don't intend to fly upside down in the near future, I'm wondering if there is any disadvantade to setting up the collective pitch with a bathtub curve. That is having lots of pitch at zero throttle with declining pitch to 50% throttle and then increasing pitch again beyond 50% throttle. The reason for setting it up this way is to have the heli have positive pitch when the throttle is quickly shut down when I get in trouble and thus allowing the heli float down instead of being driven down hard. What problems might this cause? Is there a better way to set up the collective pitch if I never plan to fly inverted?
