  • Product description

    Acro gliders need to be fast, precise and dynamic. In the case of tandems, additional traits, such as easy launching and predictable landing, are a must and I think here we don't need to write about the behaviour of the glider in take-off and landing. These properties combined with light brake forces and intuitive handling make the KOOKY 2 Bi the most comprehensive acro tandem glider on the market.

    But make no mistakes: KOOKY 2 Bi is suitable for manoeuvres such as rhythmic SAT to Infinity and tumbling!

    KOOKY 2 Bi´s character differs depending on wing-loading: Heavier payloads provide more speed and dynamic handling while light duos can make use of the trimmers to give the wing more punch. Starting to fly the KOOKY 2 Bi, we recommend beginning with a low wing-loading (light passenger) to get used to the glider´s characteristics, before getting serious.

    Target group:

    • professional tandem pilots with experience on acro solo-wings

    • acro instructors who wish to show entries and exits to students

    Key futures:

    • easy launch, as KOOKY 2 BI is solid-bearing without excessive speed

    • light and predictable (lower wing-loading) or fast and dynamic (heavier wing-loading) transitions

    • enough power for advanced acro tricks

    • transparent, forgiving and intuitive behaviour in flight

    • high passive safety

    • simple landing

  • R&D comments

    Artoosh Ghafourian:

    At the very beginning, we were thinking to have a glider that could show a different perspective of flight to people and pilots who want to see more and push their limits. On the other side, Kooky BI help me to show the correct angle of infinity to our acrobatic students and help them to reach their goals faster than they could believe it. I was looking to have a glider in the market in which I could do easy rhythmic SAT and stall exit for infinity, these were two main golden keys for us. Kooky Bi has a light brake which you could stall the glider even in infinity, reasonable brake pressure, easy climbing angle in infinity. Helicopter and much more manoeuvres that you can enjoy in the air. To be more honest with you, Kooky BI bring a lot of joy and fun for the passenger but at the same time requires a master acro pilot to handle it. As a part R&D of Sky Paragliders, I do not recommend you try manoeuvre which you are not fully master on it. It seems to be easy on take-off and feels like stone in the air but having a small tandem glider with high speed(compare to regular tandem) could turn to a point that needs an advanced pilot to control. Do not take risks for yourself and your passengers. I recommend you for the first flight with Kooky Bi take an acro pilot friend to fly with you. Compare to regular acro glider feelings are different. The glider needs more time to climb and shoot, brake ranges are different and you must pull more than what you were pulling on regular small acro gliders. A different model of pilot harnesses and spreaders could have a direct effect on the brake range too. And it is great to share your first acro tandem flight with your buddy.
