The B757 is a low-wing cantilever monoplane with a conventional tail unit featuring a single fin and rudder. It is confirmed the the B757-200 will be the next reworked aircraft coming in the upcoming v20.3 Infinite Flight update.
The cantilever is commonly used in the wings of fixed-wing aircraft. A wing that uses no external struts or bracing. All support is obtained from the wing itself. The wing spars are built in such a way that they carry all the torsion and bending loads.
A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build.
