Default Scratch Building A Biplane

I am currently flying the Valiant, but I have always liked biplanes and i am going to scratch build my own design for pattern.
I have a pretty good idea of what i will do for the fuselage, horizontal and vertical stabilisers. The area where i would appreciate advice is to do with the wing design.
The wing span will be 1850-1900mm.
I would appreciate suggestions/advice for the wing plan form, root and tip chords, root and tip sections (thickness etc), amount of stagger and incidences.
All advice greatly appreciated.

I fly my dad's design, which has no stagger, and the wings are quite foreward. The top wing and elevator both have adhedral (angled down). I flew F3a with it last year, and we have a new design for this next season

Thanks. What is the wing thickness at the root and tip?

I'm not sure, but the wings and stap are both very thin. Makes the airplane fly very smooth
