HQ Power Kites proudly introduced the HQ Hydra model in 2009, the world`s first and only water re-launchable, foil trainer kite. Now the Hydra II is here with a new vent system, reduced bridle, and redesigned cell structure for increased performance. The HQ Hydra II 420 trainer kite lets you accomplish something no other trainer kite has ever done before. It lets you train, body drag, and do kiteboarding in every environment including in the WATER. The Hydra 420 is the largest model in the lineup and will generate massive power in ways other open-cell trainer kites will never do. The Hydra 420 trainer kite is extremely stable and easy to fly even with its ability to generate lots of power. Its closed cell ram–air foil architecture has no bladders to inflate or replace and yet it floats on water as if it was inflated. The HQ Hydra II 420 Closed Cell system now features an internal drainage system with dirt-outs so you can remove debris. The Hydra’s reduced bridle is stitched Dyneema for added strength.
