ADVERSE stands for:
Avion a Decollage Vertical Et Retour au Sol Erratique,

This plane sits on its tail and can take off vertically. It can also hover in a quasi-controllable fashion. Version 2.0 of the adverse has a motor that can swivel up and down in conjunction with the elevator control. This allows it to turn on a dime.
