>> An issue with both the Osprey and the VTOL F-35 is that they each have two engines involved in VTOL. So, if one engine fails - then the plane becomes unbalanced and probably flips over.

This is not correct for the V22 Osprey. Either engine can power both rotors through the wing driveshaft.

Disclaimer: I worked with the V22 engine control system at one point (AE1107)
