Hi David --

I like the blue line -- and would extend it out to the TE at the bottom of the rudder leaving the rudder squared off. The plane is angular throughout, so I think I would retain that in the rudder outline too.

This is the fun part of the hobby -- you can take someone's plans, maintain the essence of the design and add the esthetics of your own. Are these plans going to be available? (I hope!!)

What are the basic dimensions and what airfoil are you using?
