Detailed description
The Alpina 4 GT is the EN-C wing that gives you the feel and performance of a high-end three-liner without forcing you to switch to a two-liner. Ozone designed it for pilots who loved their Alpina 4 or Delta 4 and want to stick with the same technology and behavior — but with a more robust top surface. In the air: low sink rate, easy thermalling, and a glide that goes far. But this is a C-class wing: if you don't log 70-100 hours per year and have some SIV experience, it's not for you yet, and that's perfectly fine.
From the Manufacturer
Ozone: « performance leader in the EN-C three-liner category ». The Alpina 4 GT adopts the proven profile of the Alpina/Delta 4 and adds an optimized internal structure and a more resistant top surface. All manufactured in the Ozone factory, with custom colors available.
Technologies & Innovations
- EN-C Three-Liner — the efficiency and comfort of a modern C-class wing, without the demanding piloting of a two-liner.
- Complex Internal Structure + Optimized Twist — profile that maintains its shape even in turbulent air.
- Forgiving Collapse Behavior — moderate projected aspect ratio (4.4): low tendency to pitch forward after a collapse.
- Reinforced Top Surface (new « scheme design ») — increased durability.
- Delivered with Concerto Light bag, folding pillow, line bag, and certificate of authenticity.
Flight Behavior & Safety
EN-C certified in all sizes. Intermediate to advanced wing, for pilots flying 70 to 100 hours per year and with SIV experience. Thanks to its ease of use and high level of passive safety, it is also suitable for pilots moving up from a lower category — but it requires active piloting.
Who is it for? And what size?
For the cross-country pilot who wants a forgiving and high-performance C-class wing, and for the B+ pilot ready to step up. Size selection is based on PTV: rather high in the range for stability on bar, rather centered for maneuverability. Three standard colors (PWH-P, UWA-U, LWO-L) + custom colors on request.
