The ideal C.G. position is 65mm (2.56 in) behind
the leading edge measured at where the wing

specified, add weight to the fuselage or move
the battery position. Check the C.G. before flying.
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 0.25 or 4C 0.30 engine,
using a more powerful engine does not mean better performance. In fact, over powered
engine may cause severe 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 applicable.
Adjust the control throws as shown in the
diagram. These throws are good for general
flying. You can adjust according to your
personal preference.
