Quick Overview

Important Safety Precautions

  • The first-time flyer should never fly by himself/themselves. Assistance from an experienced flyer is necessary.
  • A pre-flight adjustment must be done before flying, it is very dangerous to fly a badly pre-adjusted aircraft.
  • Long-CZ-46 is specially designed to be powered by a 2C 0.60 engine using a more powerful engine does not mean better performance. In fact, overpowered may cause severe damage and injuries. 
  • Make sure the airfield 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 a hot iron to remove the wrinkles. Please begin with a 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
