But again, I guess he is talking specifically about the Buchon here. I guess the late war 109s were more closer to the Mustang in terms of speed than the Buchon was, not to say rate of climb. As for the control forces, I don't know if the Germans improved this in the late war variants, a improvement that if occured makes me wonder if the Buchon also has had. Also: I don't know how the power curves of the 109 and P-51 compare. Because the power output of two aircraft can be different in different altitudes and this of course, will certainly affect the turning radius and rate of climb of an airplane. And in some cases the difference power output of two aircraft can be quite significative (e.g. Fw 190 A series vs Bf 109 in high altitude).
