Glaser-Dirks DG-300


The Standard Class successor to the DG-101 featues an HQ airfoil with blow-holes to inject high-energy air into the boundary layer to delay laminar separation. It has fin ballast for centre of gravity control. Approach control is by top surface Schemmpp-Hirth type airbrakes. Like other DG ships, the DG-300 features a parallelogram stick to avoid turbulence-included control inputs. Some were manufactured by Elan in Slovenia. The DG-300 Club is a simplified version with a fixed main wheel suitable for club use. Both the DG-300 and the DG-300 Club are produced in Acro models stressed for +7/-5 g. The improved DG-303 Elan model (which also comes in standard, standard Acro, Club and Club Acro variants) has a modified wing section and winglets, and a claimed L/D max of 44 and a minimum sink rate of 0.53 m/s / 1,73 fps/ 1,93 kt. Water ballast is an option for the DG-303 Club Elan.
