C.G.
# 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 or 4C 0.52 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.
Important Safety Precautions
Adjust the control throws as shown in the diagram.
These throws are good for general flying. You can
adjust according to your personal preference.

83mm
3.25 in
The ideal C.G. Position is 83mm (3.25 in) 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.
