Dave Thompson performs an amazing Fly board demonstration at Broadstairs Water Gala 2013. Fly boards are Water Jet Pack, hydraulically powered by the engine of a Jet Ski. The Jetpack system is an accessory to a jet ski or personal watercraft, also called a “bolt-on-kit”. It requires that you already own a “personal watercraft” or jet ski with enough power to do the job. ( Needless to say, it does not come with its own water pump powerplant like the much more expensive Jetlev system. ) The system uses the power of the jet ski engine to pump the water and supply enough pressure to lift the jetpack and rider into the air. You must have, or purchase a jet ski unit on your own and add the jetpack unit to it by modifying the nozzle section at the rear or the ski with a Jetpacks supplied kit. The jet ski can be returned to its initial state at any time by mechanically removing the adapter kit. Due to the power requirements, a high output jet ski is required. We are building for Seadoo musclecraft similar models from Yamaha and Kawasaki. The thrust of the water from the jetski is redirected 180 degree to the front of the craft and up a 20 meter long hose to the jetpack. The fast moving, powerful stream of water is then split into two thrust streams which are independently controlled by the rider with the steering arms. Classic jetpack physics invented in the 1950′s. By controlling the angle and differences in angle, the rider can move forward and turn right or left in any direction. The hose acts as a towing connection to the jetski, wherever the jetpack rider turns, the jetski powerunit is towed behind. When riding the jetpack, this action takes place naturally and the jetpack riders is generally unaware of the jetski unit following behind. The Jetpack system requires two people to operate. One rider on the jet ski, controlling the throttle and the power of the water, the second person, the jetpack rider controlling the direction and angle of the water jets.
