The Skyhawk has one of the best looking vertical fins on any aircraft. This model has it in multiple sections and parts.
There are also two options for the rudder and you have to make a decision upfront because some surgery is needed. One option has the rudder rendered to show the side stiffeners on the rudder plate. This is incorporated to the fin and nothing else is needed. The second option is to cut out the area of the stiffeners and build all of them as an assembly. However, for my version, I removed the entire rudder from the fin in order to build it as one unit.
Here are the parts
and the internal supports
note that the red hatched area will be cut out to accommodate the separate rudder
a little trial check
cut out the red area
added card stock where the horizontal support will be drilled thru
fin is assembled as one unit
dry fit
The final fit is great.
