Hoi Frank,
Ten eerste super respect hoe je na 30 jaar een super mooie Dog maakt, hij is super mooi geworden
Alleen inderdaad zoals er al iemand had aan gegeven hebt je op de hoogte roer de Vortex generator aan de boven zijde gezet terwijl ze aan de onderzijde moeten zitten.
A
vortex generator (VG) is an aerodynamic device, consisting of a small vane usually attached to a lifting surface (or airfoil, such as an aircraft wing) or a rotor blade of a wind turbine. VGs may also be attached to some part of an aerodynamic vehicle such as an aircraft fuselage or a car. When the airfoil or the body is in motion relative to the air, the VG creates a vortex, which, by removing some part of the slow-moving boundary layer in contact with the airfoil surface, delays local flow separation and aerodynamic stalling, thereby improving the effectiveness of wings and control surfaces, such as flaps, elevators, ailerons, and rudder
