I have flow fixed pitch electric copters for over a year now. This is the first time at trying a collective pitch copter. I have a blade cp that I am trying to fly. My question is: Is it normal for collective pitch copters to be a lot more sensitive on the throttle? It is very difficult to keep a constant altitude. If I bring the throttle stick down a little too much the copter comes down fast and if I give it a little too much throttle the copter shoots up fast. Any help would be appreciated.
