They were single bay biplanes, their wing interconnected by N-form interplane struts assisted by wire bracing.
These interplane struts leaned outwards and narrowed to meet the closer spars of the smaller-chord lower wing.
[1] At the rear, the tailplane was mounted on the upper fuselage structure and externally braced to it from below with pairs of inverted V struts.
Its fin was small and round edged, carrying a broad, deep rudder which reached down to the keel.
[2] The Potez 26 had a fixed tail wheel undercarriage with mainwheels on a split axle supported centrally by a V-strut, hinged on another pair of struts to the lower fuselage and with vertical, airfoil section shock absorbers.
