The wing is similar to the one of Re.2000 and it's a metallic and cantilever wing.
It's composed by 5 parts: - central section - 2 half wings - 2 wing tips
In more detail: A - Central section B - Half wings C - Wing tips D - Ailerons E - Flaps
Note landing gear resting position (round details) and coolant and oil radiators (squared details)
The wing is composed by: - 4 wing spars (5 for prototypes) - metal sheet wing ribs sections with holes for weight reduction - wing top surface stiffened by corrugated metal sheet - wing bottom surface stiffened by curled-stringers
The wing planform is elliptical (actually almost-elliptical) and: - airfoil thickness is decreasing from centerline to tip - biconvex asymmetric airfoils
