Tail surfaces - 109F versus 109E?

[klemchen]

Hello,
mmoustaf's drawings are real interesting. They confirm that the rudder axis for the F was moved aft by 39 mm: Its distance longitudinally from the main wing spar (i.e. from the bridge going through the fuselage to which the wing spars were attached) is given as 5262 mm for the E and 5301 mm for the F. According to the drawings, the elevator axis was in exactly the same place for both models, despite different construction of the tailplanes (two pieces for E, one piece for F).
I am not maintaining that the outlines of the vertical tail for the E and the F were the same. The difference of the fins was very slight, but the E rudder was longer than it should be according to my theory. However, there is a discrepancy between George Hopp's Mtt. drawing and mmoustaf's E drawing, also by Mtt.. On the former, the outlines for E and F are the same, and the length of the rudder is specified as 634 mm,
i.e. 19 mm less than on the latter and precisely 39 mm more than the 595 mm of the F rudder.
George Hopp's drawing was made by the flight characteristics department on January 27 in 1941, that of mmoustaf on September 13 in 1942, probably by the same department ("Fleig" stands certainly for Flugeigenschaften = flight characteristics). At that time no E was built any more, so the drawing cannot have been used as a basis for construction. But what was it for then? And how reliable are drawings by Mtt. anyway?
