The DELTA 3 is a significant step forward in performance and handling:
- Increased glide performance
- Increased glide at accelerated speeds
- Higher top speed
- More precise handling, better agility, and a sharper feel
- Same AR to keep the same level of accessibility, “compactness” and forgiveness.
- 4 more cells to improve the sail tension, cleanliness and precision.
- The planform is revised to improve airflow at the tip in accelerated flight.
- Double 3D shaping for a perfectly clean LE.
- Patented OZONE SharkNose profile with the same intake position for great handling and internal pressure at higher speeds (carried forward from D2).
- New nylon rod reinforcement at the back of the profile to improve the surface and reduce drag.
- Despite the addition of more cells, we managed to optimise rigging and save another 4% of line drag!
- Internal structure has been revised to make the sail lighter, and to improve the mechanical behaviour. New ports in the diagonals, the addition of straps, and new port shapes and positioning in the ribs.
- There is a new version of shrink tabs in the brakes, allowing increased freedom in the TE at top speed, yet offering the necessary tension for the turn precision that we like.
ACTIVE C RISER CONTROL
When gliding at trim or in accelerated flight it is possible to pilot with the C risers. This gives an improved feel and control over the wing, enabling you to fly actively without using the brakes (which cause drag and pitch movements). The direct feel allows you to stop collapses before they happen and maintain higher speeds and higher levels of efficiency through turbulence.
To fly with the C risers, keep hold of your brake handles (remove any wraps) and take hold of the handles located at the top of the C risers, or just the C risers themselves. With the C risers you can fly actively through turbulence; If you feel the nose of the wing lose internal pressure you can apply pressure to the C’s to keep it open. The amount of pressure and size of the input is dependent upon the amount of turbulence, but always be gentle at first to learn the feel of the movement and to avoid large pitch oscillations.
The Delta 3 is inherently stable at full speed. C riser control is very effective up to about ¾ speed, however during the last few cms of speed bar travel C riser control on its own becomes less effective. When flying faster than ¾ speed, we recommend to control the pitch of the wing actively using a combination of the speed bar and C riser input. If you feel the nose of the wing start to collapse the first action should be to release the speed bar slightly – but impulsively – and then make any necessary C riser input, always action with the speed bar first before making any C inputs. Using the combined active speed bar/C riser control technique you will be able to maximise your speed and efficiency whilst minimising the likelihood of collapses.
NOTE: Active C riser control is suitable for gliding in good ‘normal’ air without serious turbulence, it does not replace proper active flying using the brakes in strong turbulent conditions. If you are unsure about the air, return the glider to trim speed, release the C risers, and fly the glider actively with the brakes.
