Technology - DESiE Flight Simulation X-Plane
DESiE  in X-Plane Since   last   year   it   is   possible   to   equip   an   airplane   with   electric   drives   in   X-Plane Ver   9.22   and   higher.   Unfortunately   a   folding   propeller   is   not   available.   So   the flight characteristics while soaring still need to be corrected. In    ‚X-Plane'    you    can    carry    out    different    flight    tests    with    your    experimental airplane.   Of   course   every   simulation   is   as   good   as   your   input   parameters.   In our   case   we   verified   the   take   off   run   time   with   ‚Mathematica'      where   you   can solve   the   differential   equations   numerical.      The   results   are   in   good   agreement with the estimated times in X-Plane.
