ECO

 - the electric  helicopter is designed and developed in germany. 

Years of experience assisted in producing this helicopter.

Energy 

eco

nomics  is  the  most  sensible  subject  in  creating  a 

helicopter  with  an  electric  motor.  12-20  cell  batteries  and  charging 

equipment  is  available  at  very  favorable  conditions  so  this  had  been  the  target  we  had  to  reach.  The  basic 
design  is  extremely  lightweight  though  still  very  solid.  The  special  chassis  eliminates  weight-consuming 
screws  and  parts.  Ball  bearings  on  all  moving  parts  reduce  the  overall  friction  in  the  mechanical  section. 
Various pinions are available to adopt the transmission and the tailrotors speed to the motor and to the flyers 
habits. A belt drives the tailrotor with hardly any loss of power. The special mechanical mixer allows the use of 
a  standard  4  channel  r/c  without  electronic  mixing  facilities.  Those  who  tend  to  use  an  advanced  electronic 
r/c-system  can  easily  use  a  4  x  90°  swashplate  program  with  3  servos,  eliminating  even  the  weight  of  the 
mixer. The steering is designed to be strong and very efficient. Flying the 

ECO

 means first class 

eco

nomics 

and  professional  flying  potential  -  for  the  beginner  as  well  as  for  the  3D  ambitious.  A  wide  variety  of  tuning 
parts for even less weight or more performance is available in your hobby store. Ask your dealer for IKARUS 
parts.
