The Synergy 333 is a 3 line kite controlled with one hand. Originally the kite was available in 3 different sizes; the Minergy Zero Wind 333, the Zero Wind 333, and the outdoor version simply known as the Synergy 333.
The sail is held taught by 3 carbon spars and a sophisticated arrangement of 15 tension lines. The framework can be fitted to either the front or the back; on the front it's easier to fly, but when fitted to the back it's faster and flies in less wind.
The three flying lines are attached to the three points on the handle. The handle is a similar arrangement of three spars strung together; it can be tipped in any direction to control the direction of motion, but for fine speed control you can simply flex the lower spar with the fingers.
The kite is completely omni-directional and can even be made to spin. You will enjoy flying this kite if you have the patience and tenacity to master it - the basic technique can be learned in a single session but it takes longer to become proficient.
The standard version needs a reasonable wind to fly. The Minergy 333 version behaves almost more like a string puppet than a kite and, weighing only 14 grams, can be flown indoors on its diminutive 3-foot lines. The benefits of flying 1 kite in one hand is that your other hand is free to pick up another and fly one kite in each hand to create patterns with the two kites.
