I decided this the way to go. After cutting the leading edge off of the rudder back to the balsa "false leading edge", I found I still didn't have a large enough gap between the fin and the rudder. I can cut off part of the fin or I can cut back the rudder some more which will essentially remove the balsa leading edge which will then require replacing. Did anyone else go this route and how did you end up doing it?
