# 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 80c.c. engine, using a more powerful
engine does not mean better performance. In fact, over powered engine may cause structural
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.
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.
