Tracing the airfoil at the aileron/flap junction gives a max thickness of 13.7% at 38% chord.
Airfoil tools gave the closest reasonable aerofoil as the Tempest

Did Kurt Tank base his airfoils on the NACA series, similar to both Heinkel and Messerschmitt?
In the mean time I made a scan of the Ta 154V1 drawing and did pixel counts.To me it looks more like about 35 % using that drawing.
From a better drawing in Dietmar Hermann's latest Ta 154 book page 77 showing some V1 wing profiles I estimate about 30 % for the inner wing and about 35 % for the outer wing.
It is difficult to determine exactly where the wing is thickest but I think it is slightly behind the front spar.
I missed the "Fw". Here is an overlay - it looks like they filled in some of the dent under the nose at the root. As to the other airfoil, its not the tip, as its way too thick.The designation on that drawing is "NACA Fw 43016" which seems to indicate that FW have modified the base NACA 43016 airfoil.
Comparing the NACA 43016 with the root airfoil shows they are not the same.
What information do you have for the root and tip airfoils on the Fw 189?Fw 189, 190 and Ta-152 used the 5 digit NACA 230 series. See here for the 190 and 152.
What information do you have for the root and tip airfoils on the Fw 189?
Until tomo comes up with a better drawing, here is one for the Fw 189 V6 indicating wing profile NACA 23016/10 which I suppose means 23016 at root and 23010 at tip.What information do you have for the root and tip airfoils on the Fw 189?
