CENTER OF GRAVITY
An important part of preparing the aircraft for fl ight is properly balancing the model.
1.
Attach the wing to the fuselage. Make sure to connect the leads from the aileron to the appropriate leads from the
receiver. Make sure the leads are not exposed outside the fuselage before tightening the wing bolts. Your model
should be fl ight ready before balancing.
2.
The recommended Center of Gravity (CG) location for your model is 85 mm behind the leading edge of the wing.
3.
When balancing your model, make sure it is assembled and ready for fl ight. Support the plane inverted at the
marks made on the wing with your fi ngers, or a commercially available balancing stand.
The suggested Center of Gravity (CG) is the recommended balance point for fi rst fl ights. This provides a safe and stable
setting so you may comfortably explore the performance and handling of your model.
The CG Range of 80 mm to 95 mm is the extremes of balance to which the model was fl ight tested, and found to be
fl yable. The stability and performance of the model will vary when adjusted within this range. As each pilot’s fl ying style
and preferences are different, we suggest that you make small adjustments to the CG until you fi nd the feel that you
prefer.
CAUTION: You must adjust your aircraft’s center of gravity
and balance your model properly before attempting fl ights.

PUSHROD CONNECTIONS
Before checking the control throws, make sure the pushrods are
connected to the servo arms as shown to achieve the correct
amount of control throw.
Elevator
Ailerons
Rudder
Control Horns
The clevis must be attached to the outer hole of the control horn
for the rudder, elevator and ailerons to achieve the correct amount
of control throw.
These are the recommended connections for the pushrod locations
for your fi rst fl ights. The pushrod locations can be changed
to increase or decrease the amount of throw once you are
comfortable with the fl ight characteristics of your model.
