1. An air vehicle comprising:
at least one propeller, each propeller comprising at lease one blade having a constant pitch angle; at least one propeller motor configured to reverse propeller rotation rate of the at least one propeller while the air vehicle is in flight; and an autopilot configured to maintain airspeed of the air vehicle above stall conditions while the air vehicle is in flight. |
