The invention relates to an improvement of the device for assisting turning of ultralight gliders more commonly called "deltawing". The ultralight glider consists of a structure composed of two leading edges 1 and 2, of a crosspiece 3, of a sail 4, of a trapezium 5, of a mast 6, of a keel Q and of a control bar 14. The crosspiece is composed of two symmetric half-crosspieces, capable of being folded onto themselves in the plane of the sail 4 as they are articulated around a shaft h which is perpendicular to the plane of the sail, being displaced along the keel Q. The mast is articulated in a U-shaped support fixed vertically onto the articulation shaft h of the two half-crosspieces 3. Each trapezium upright 5 is articulated at one of its ends to the control bar 14. The other end is articulated to the respective half-crosspiece by a shaft parallel to the keel Q and passing through each half-crosspiece 3 in such a way that the trapezium upright 5 can be folded parallel along the crosspiece 3. The keel Q will be situated between the trapezium uprights 5 and can thus be moved from one trapezium upright to the other. It can rest in a horizontal cradle 15 situated between the trapezium uprights and fixed to them. <IMAGE>
