The next step is the fin correction.As it was mentioned by a few guys here it is of incorrect width.I can agree with it but to a certain extent only.
Comparing to the Kagero drawinds it appeares too short and it has to be made higher.Its width is incorrect at the low area only but it is of less then 1mm.I was thinking about correction to that quite long because the mistake is quite small, but a surgery is a surgery and I decided to correct it by changing to the fin leading adge.In the second pic you can see what I mean.The rotate point is a point where the incorrect leading edge has to be rotate right to get a proper angle.
I started the correction with cutting off halves of the rudder.In the last pic you can notice that the rudder is of a quite correct shape but it is too narrow.
