You are correct, more trimming. Here's a photo of the trimming complete to allow the rudder full movement.

An issue with this rudder is that it is hinged only at the top and bottom. Flight and torsion loads are transmitted through the trailing edge (yuck). To deal with this, I have added carbon fiber cloth to both sides of the rudder TE. It's quite strong now!
