Where would be a good starting point for a safe first flight CG location. The tail has not yet been designed yet. Here is a image of my design; the shaded area represents the suspected CG region.

Since the image did not upload to scale the dimensions are as follows:

*Center Panel: 7.6x23cm

*Inboard Panels: 381x254mm (7.6deg swept)

*Outboard Panels 381x254mm (11.4deg swept-from center panel; 3.8deg from inboard panels)

*Tip Panels: 190x254mm {(19deg swept from center panel) 9cm tip chord en 254mm root chord} *** Tip Panels will be at 45 deg angle from center panel...

airfoil is NACA 6409 (constant chord swept wing)
