An airborne vehicle (fig.1,10) has a propulsion system with a pair of motion inducing members 18 such as paddles, one on each side of the vehicle, which are driven by a drive arrangement 32,34,36 so that they simultaneously rotate and flap to provide thrust. Preferably the paddles are substantially planar and rotate about a transverse axis so that two flaps are completed for each complete rotation. The drive arrangement may include a pair of cranked connections onto which the paddles are mounted at an incline to the axis of rotation; the degree of inclination of each paddle may be manually controlled separately by a pilot in use. Front and rear propellers 42,48 may be provided on a longitudinal axle (fig.1,46) of the vehicle. The propellers may be driven by an internal combustion engine 56 which also drives an electric generator 58. The generator may be used to charge a rechargeable power source of an electric motor 36 used in the drive arrangement. The propellers may be located within casings 44,70 having inlets 64,72 and outlets 68,74 with controllable flaps 66,76 to vary their extent and/or orientation.
