Ray and Jeanne Merry update the Flowform. With its uniquely vented design, the UltraFoil 9 has a very wide wind range. In light winds, its tall airfoils get more lift. The lower vents aid in initial inflation and the upper vents relieve pressure. In strong winds, the dynamic trailing edge vent opens to release a stabilizing jet of air. A high angle flier with good, consistent pull, it's perfect for lifting Line Laundry. Made of ripstop nylon, it needs no assembly and has nothing to break. Wind range: 5 to 30 mph. 14-ft ripstop nylon tail. 8" x 13" case. 2'-4" x 3'-9". Ready to Fly with 300' of 80-lb. braided polyester line on a hoop.
