The MAI-920 was developed from the powered Oskbes Aviatika MAI-890 ultralight, which can also be used to aerotow the MAI-920 glider. The MAI-920 has a 90% parts commonality with the MAI-890. The glider design uses a higher aspect ratio monoplane wing in place of the MAI-890's biplane wing. It is intended to be a simple and robust student solo glider.
The MAI-920 glider is made from aluminium tube and fabric, with the nose cone built from fibreglass. Its 101NaN1 span wing is cable-braced from a kingpost. The landing gear is a fixed monowheel gear, with a nose skid or caster and a tail skid.
