I am starting a new glider project and would appreciate recommendations or opinions on the dihedral angle. I am exploring two options:

1: Single dihedral break at the center (shown on plans)
2: Two breaks with a flat center panel (slight dihedral break at tip panel giving a 71" center section, flat, with a 35.5" tip section, this is where the break would be)

The kit wing comes in four sections, left and right center section and left and right tips. All sections measure 35.5" in length
Wing specs are as follows:

WS: 142" Plans show 78mm rise from center to tip PER SIDE, 156mm total for dihedral
Root Chord: 9.5"
Tip Chord: 4.5"
Straight TE with the typical LE taper

Sailplane is full function Ail/Flap and V-tail

If I go stock I will build it with the angle shown on plans. If I build the straight center section and break at the tips, what angle would you folks suggest?

Thank you all in advance!
