| History: |
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. Some were manufactured by Elan in Slovenia. |
| Notes: |
The DG-300 has fin ballast for center of gravity control. Approach control is by top surface Schemmpp-Hirth type airbrakes. Like other DG ships, the –300 features a parallelogram stick to avoid turbulence-included control inputs.
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. The wing section was modified for lower drag, espacially for better high performance. The winglets will improve the performance in thermalling and the max. L/D (increase app. two points glide angle). In addition the winglets improve dramatically the handling characteristics while thermaling. This is another source of better climb performance.
