engine using  a

more  powerful engine does not mean better performance.  In fact, over powered engine 

   

may cause severe damage and injuries.

#  Make sure the air field is spacious, never fly the plane too close to people and never get

  

too close to a running propeller.

#  If you find wrinkles on the covering as a result of weather changes, you can use hot iron 

  

to remove the wrinkles.  Please begin with lower temperature setting and gradually raise 
the temperature until the wrinkles are gone.  Too hot an iron may damage the covering.

#  Check and re-tighten up all factory assembled screws, use thread locker if applicable.
