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 designed for high speed flying. Too low an air speed during take off or landing
may canuse tip stall. Point the UniJet towards the wind, use full throttle and let the UniJet
gain enough ground speed before pulling the elevator gently for take off. For landing,
approach against the wind, maintain power to the ducted fan to keep enough air speed
before touch down.
# Make sure the air field is spacious, never fly the plane too close to people and neverget
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.
Warning!
The ideal C.G. position is 57mm ( 2.25in ) behind the leading
edge measured at where the wing meets the fuselage. In order to obtain
the C.G. specified, add weight to the fuselage or move the battery
position. Check the C.G. before flying.
