Important Safety Precautions
# 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 2C 0.40 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.
# Check and re-tighten up all factory assembled screws, use thread locker if necessary.
