If you increase the dihedral the right amount, I don't think you need to add much at all to the fin and rudder. Very approximately, after measuring mine I get a Vv of .021. Allegro Lite has .024. Also, Allegro Lite moment is something like 26 inches or a tiny bit more, Metrick around 25 inches or so. That's pretty close. I suspect it will have significantly better damping than a Sagitta 600.

I also plan to enlarge the rudder abit to help with turning.
Thanks in advanced for any thoughts on this and on building the Metrick
