Jeffrey; note that if your GN-1 is built per plans, the cabane struts will be vertical because the wing cannot physically be moved aft on a GN-1. The attachments for the struts do not create "pivoting four-bar linkages" as they do on the Pietenpol. And don't start worrying about W&B before you know ...
