Center of Gravity
An important part of preparing the aircraft for ight
is properly balancing the model.
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location for
your model is 2 5/8 (67mm) to 3 1/8 inches (79mm)
behind the leading edge of the wing where it meets
the fuselage.
Mark the location for the Center of Gravity on a piece
of low-tack tape on the top of the wing next to the
fuselage as shown. When balancing your model,
support the model inverted at the marks made on the
top of the wing with your ngers or a commercially
available balancing stand. This is the correct balance
point for your model. You may nd you need to add a
small amount of weight to either the front or back of
the fuselage to achieve the correct balance.
Control Throws
􀀀 Ste 1
Turn on the transmitter and receiver of your model.
Check the movement of the rudder using the
transmitter. When the stick is moved right, the rudder
should also move right. Reverse the direction of the
servo at the transmitter if necessary.
􀀀 Ste 2
Check the movement of the elevator with the radio
system. Moving the elevator stick toward the bottom
of the transmitter will make the elevator move up.
􀀀 Ste 3
Check the movement of the ailerons with the radio
system. Moving the aileron stick right will make the
right aileron move up and the left aileron move down.
􀀀 Ste 4
Use a ruler to adjust the throw of the elevator, ailerons
and rudder.

Note: Measurements are taken at the inner or
widest point on the control surface.
These are general guidelines measured from our own
ight tests. You can experiment with higher rates to
match your preferred style of ying.
Note: Travel Adjust, Sub-Trim and Dual Rates are
not listed and should be adjusted according to
each individual model and preference.
