<div class="htmlview paragraph"><b><i>HELIos</i></b> is a single seat, three wheel, vertical take-off and landing (VTOL) flying car concept. It uses duct enclosed counter-rotating propellers. This technology eliminates the need for a tail rotor and makes the vehicle more compact. It needs no modification to switch between drive mode and flight mode. It uses a modified motorcycle or snowmobile engine for road travel and a two-stroke, aircraft, diesel engine for air propulsion. It is flown by wire for directional control, and a helicopter pitch control is used for vertical motion. <b><i>HELIos</i></b> is equipped with a guidance control system for safe and precise flying. In emergency cases, the driver/pilot can employ a ballistic parachute, which allows the vehicle to float safely down to earth. It will be street legal under the rules of the Department of Transportation (DOT); its three-wheel design categorizes it in the motorcycle and scooter category.</div> <div class="htmlview paragraph"> <div class="table-wrap" id="T1"> <div class="graphic-wrapper"><img class="article-image tableFig" src="985535_fig0001.jpg" alt="No Caption Available"/></div> <div/></div> </div>
