# First time flyer should never fly by himself / herself. Assistance from experienced flyer is

absolutely necessary.

# Pre-flight adjustment must be done before flying, it is very dangerous to fly a badly

pre-adjusted aircraft.

# is specially designed to be powered by 4 stroke . engine, using

　a more powerful engine does not mean better performance . In fact , ove r powered engine

# 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.

Don’t use hot iron near the seams or edges, hot iron will melt the glue and shrink the

covering at the same time, causing the seams to pull away.

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