DESCRIPTION 

The  Dynali  H3  EasyFlyer  Sport  is  an  ultralight  two-seat  helicopter  in  a  side-by-side 
seating configuration. The main structure is a stainless steel chassis which frames the 
engine, the cabin, the tail structure and all the main and rear transmission. 
  
The  main  rotor  mast  is  made  from  steel  and  the  main  rotor  blades  are  in  extruded 
aluminum or molded carbon. The rotor head is controlled by push-pull rods through the 
swash plate. 
 
The tail structure is made of an aluminum boom, supported by two carbon tail struts. 
The tail rotor blades are formed in carbon and are controlled by push-pull cables. The 
cabin cell and the stabilizer are made from vacuum infused carbon fiber and the canopy 
is in perspex.
