After installing the battery (in the recommended position) and before power-
ing on the ESC, verify the CG. The CG location starting point is 73mm (range:
73mm±3mm) behind the leading edge, as shown.
3S 2200mAh Smart battery CG position – The battery is installed all the way
forward in battery compartment. Only the front battery strap will be used.
4S 3200mAh Smart battery CG position – The battery is installed centered in
the battery tray, using both front and rear battery straps.
Balance the aircraft inverted on your fingertips adjacent to the fuselage under
the wings.
• If the nose goes down, move the flight battery back until the aircraft balances.
• If the nose goes up, move the flight battery forward until the aircraft balances.
Center of Gravity (CG)

73mm ± 3mm behind
the leading edge at the
wing root.
Control Surface Direction
Switch on the transmitter and connect the battery. Use the transmitter to
operate the aileron, elevator, and rudder controls. View the aircraft from the
rear when checking the control directions.
NOTICE: Bind the aircraft and transmitter before performing these tests.
Move the transmitter controls to make sure the aircraft control surfaces
move correctly and in the proper direction. Make sure the tail linkages move
freely.
Elevators
1. Pull the elevator stick back. The elevator should move up, which will cause
the aircraft to pitch up.
2. Push the elevator stick forward. The elevator should move down, which will
cause the aircraft to pitch down.
Ailerons
3. Move the aileron stick to the left. The left aileron should move up and the
right aileron should move down, which will cause the aircraft to bank left.
4. Move the aileron stick to the right. The right aileron should move up and the
left aileron down, which will cause the aircraft to bank right.
Rudder
5. Move the rudder stick to the left. The rudder should move to the left, which
will cause the aircraft to yaw left.
6. Move the rudder stick to the right. The rudder should move to the right,
which will cause the aircraft to yaw right.
Control Centering
After assembly and transmitter setup, confirm that the control surfaces are
centered. If the control surfaces are not centered, mechanically center the
control surfaces by adjusting the linkages.
If adjustment is required, turn the clevis on the linkage to change the length
of the linkage between the servo arm and the control horn.
After binding a transmitter to the aircraft receiver, set the trims and sub-
trims to 0, then adjust the clevises to center the control surfaces.
