60° zig-zag turbulators are installed on both sides.
Prior to removing the turbulators mark the positions of the turbulator leading
edges with a pencil on the fin surface, otherwise see table below. The
dimensions a are from the fin leading edges up to the trailing edges of the
turbulators. The lower ends of the turbulators are at the fairings for the rudder
cables.

200 mm above the upper side of the lower rudder
mounting bracket
b) Seals
As seals 30 mm (1.2 in.) wide Mylar seals with scarfed leading edges are
used, so that no step occurs.
Note: Don't glue the film tape to the leading edges of the seals. The scarfed
leading edges of the seals must be pressed to the fin surfaces by PVC tapes.
Prior to removing the seals mark the leading edges with a pencil to the fin
surfaces.
