Syrphus®  -  The innovative Tiltwing (VTOL) Design Are you searching for an airframe sollution for Mini UAV (Unmanned  Aerial Vehicle) applications that can surmount a long distance in  economic (aerodynamic) flight and then switches to hover mode  for close and steady observation? While Quadrocopters are operating between 0 and 25 mph and fixed  wing UAVs between 20 and 60 mph Syrphus® UAVs have both  capabilities without losses towards common fixed wing configurations. In general, hybrid  airplanes are based on expensive mechanics and a complex FCS (Flight Control System), but  with the ease of the hoverfly Syrphus® UAVs are performing the transition between hover and horizontal flight and vice versa using the full spectrum of velocity. The electrically driven Syrphus® UAV is the only Tiltwing/ Tiltrotor UAV below 8 lbs MTOW  (Maximum Take-Off Weight including 10 000 mA/h battery power and e.g. Bental´s  MicroBAT 275 color daylight camera) and that features the ability of Vertical Take-Off and  Landings (VTOL) from and on water.  The small packaging footprint of the Syrphus® “Io” will be only 28 x 13 x 6 in due to a  foldable wing mechanism.  * Pat.
