While in-flight loss of control has remained a severe threat to aviation, few of the upset recovery approaches designed by aeronautical research has been demonstrated in flight tests. Enabled by the ongoing success of micro air vehicles, we discuss the concept of an aerial experimental platform for upset recovery, EDURA (Evolvable Demonstrator for Upset Recovery Approaches), allowing cheap and flexible flight demonstrations. The aerodynamic coefficients of the vehicle presented here are numerically computed and extended to a full-envelope aerodynamic model using piece-wise polynomials in pre-and post-stall. Eventually, the aerodynamics are verified with wind-tunnel force measurements for a 3D-printed mock-up.
