A system for controlling yaw during vertical take-off and landing (VTOL) operation of an airborne craft, where the airborne craft comprises multiple crossflow fan lift, propulsion and control elements (LPCEs) disposed around a central longitudinal fuselage in a compact quadrotor format comprises: means for vectoring the thrust from one or more of the LPCEs on one side of the craft from a substantially vertical direction as it will be arranged for VTOL operation to a more horizontal forward or rearward direction, generating a forward or rearward thrust component perpendicular to the LPCE rotor axis, and means for adjusting the rotor speed to compensate for the loss of vertical lift, where the forward thrust component from a front and/or rear Right Hand LPCE or rearward thrust component from a front and/or rear Left Hand LPCE produces a clockwise torque when viewed from above about the central vertical axis of the airborne craft and the rearward thrust component from a front and/or rear Right Hand LPCE or rearward thrust component from a front and/or rear Left Hand LPCE produces an anticlockwise torque when viewed from above about the central vertical axis of the airborne craft.
