Customized responses for some aircraft about roll, pitch and yaw. Plane is trimmed (but, for that era, would be more appropriated "rigged") to be approximately neutral around the three axis at the top speed of the 4000 metres (where applicable - otherwise that at the highest available altitude); this should be empirically suited for cruise speed at lower altitudes (better than stock cruising speed, often quite high or a bit too low). Also throttle curve has been revised, to get always the customary power increase forwarding the throttle, as well as to have more precise response at higher percentages, where more often the throttle ranges.
