I am wondering about your question. When you say full throttle has been reached do you mean that the throttle barrel has reached its end of travel. This problem mean that you are going to have to adjust the linkage manually like the previous poster have said. If you mean that the throttle power curve is not acting linearly even though you still have movement available in the throttle barrel then you have to put expo on the throttle to linearlize the throttle stick movement. This does not supersede manually correcting the throttle linkage throw. expoing the throttle only makes it feel linear and having more fine control in the beginning of the power curve and consistent power increase through the last few clicks of the throttle control. This is my prefered settings but others might not want to do these things
