Same feeling, better performance: The top speed of the A3 has been increased and glide performance – particularly in accelerated flight – shows significant improvement throughout the speed range. We have paid special attention to the handling behavior, concentrating on the precision of the brakes, especially in the first part of the range to create an efficient, elegant, and agile climbing machine. Compared to the D3, the Alpina 3 has even crisper, more agile, handling. It must be experienced to be believed.
This is a lightweight XC machine designed for a wide range of pilots. It is suitable for those stepping up from the EN B categories and for more experienced pilots who seek comfort and ease of use in the performance XC class. Alpina 2 pilots will feel comfortable immediately and appreciate the improved handling and more precise feel.
All of the groundbreaking technology that has kept our performance wings consistently at the top of competition rankings is present in the A3. The most recent evolution of our OZONE Performance Project arc is present, and the sail cohesion, both spanwise and chordwise, is all improved. The early section of the control range is much more responsive, making micro-adjustments easier and improving thermalling performance significantly.
While the industry trend in this class of wing is to increase aspect ratio and squeeze the wing through EN tests, we decided to maintain the moderate and comfortable AR of the Alpina 2.
Overall, the Alpina 3 is a high performance travel / hike and fly wing, ideal for experienced pilots who value low weight and low packing volumes without compromising performance.

*Weight with standard risers – lightweight risers are not available.
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 Alpina 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.
