CENTER OF GRAVITY VERIFICATION
20
The center of gravity (CG) location for the QQ Extra 300G2 is
aligned with the front edge of the lower belly hatch.
This
location was determined from many test flights by designer and
multi-time world aerobatic champion, Quique Somenzini. Lift the
airplane from the underside of the wing to check CG.
Setting the center of gravity is one of the most important steps for
success, particularly with a new airplane. The QQ Extra 300G2 is a
high-performance airplane with large control surface throws, and a
high thrust-to-weight ratio. These two factors combined make it a
very enjoyable aircraft to fly, but if the CG is not within an
acceptable range, it will make the aircraft difficult, if not impossible
to control.
NOTICE
The CG measurement should be made with the completed
airframe with all components (batteries, servos, receiver,
linkages, hardware, etc.) installed. Failure to do so will result
in an inaccurate measurement.
PRE-FLIGHT CHECKS
To help ensure a successful first flight, as well as many flights after, perform a few simple pre-flight checks to ensure the aircraft is ready for
flight.

Verify control surfaces are properly hinged and in good working order. Pinch a control surface between your thumb and fore finger, and
stabilize the wing with your other hand. Give the control surface a firm pull away from the wing. The control surface should not come
unhinged from the wing. Be sure to avoid over-stressing the part, as an aggressive pull may cause the surface to come unhinged even
though it is hinged properly.
If hinging is loose, do not fly.
Apply thin CA to the loose side(s) of the hinge(s) to resecure.
Verify that all hardware and all other aircraft parts are properly secured. This includes hardware and parts installed by the factory.
Verify your battery is fully charged and in good working condition. Avoid using batteries with swollen cells, or batteries that do not
charge back to their full capacity.
Verify the CG is in the proper location, and the battery is well secured in place.
Ensure the Aura is on and functioning properly. Power on your transmitter, followed by the aircraft. Ensure the Aura is calibrated
properly and receiving a valid radio source (solid solid green LEDs). Verify that the Aura is secured well to the airframe.
Verify transmitter stick inputs result in the proper control surface movements (reference page 17).
Verify aircraft movement results in proper Aura sensor corrections (reference page 18).
Verify the motor and ESC function properly. Point the aircraft in a safe direction, and away from any objects or limbs that could become
entangled in the propeller. Hold the aircraft firmly so that you are behind the aircraft. Smoothly advance the throttle to full and back to
idle. Listen and watch for any odd or unusual behavior from the motor and ESC.
