Control Throws
C.G.
P.10
Adjust the control throws as shown in the diagram.
These throws are good for general flying. You can
adjust according to your personal preference.
The ideal C.G. position is 80mm (3.15 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.
# 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.
# Check and re-tighten up all factory assembled screws, use thread locker if necessary.
# Make sure the air field is spacious, never fly the plane too close to people and never get too close to
a running propeller. Extreme caution should be exercised when working with electric powered models.
Make sure the propeller is cleared of all objects, especially your hands before connecting the battery to
the model. Make sure you understand the operation of the ESC (Electronic Speed Control) by studying
the ESC manual. Once you plug in the battery for electric powered model, always treat the propeller as
a rotating one, as accidental movement of the throttle stick will spin the propeller and could cause injuries.
# 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.
# is specially designed to be powered by 450W Motor System.
