CENTER OF GRAVITY
The location of the center of gravity for the QQ Extra
300 is aligned with the
FRONT EDGE
of the
RADIO
HATCH
. This measurement was determined from
many test flights by designer and many time world
aerobatic champion, Quique Somenzini. Lift the
airplane from the underside of the wing to check the
CG.
Setting the center of gravity is one of the most
important steps for success, particulary with a new
airplane. The Extra 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 center of
gravity is not within an acceptable range, it will make
the airplane difficult, if not impossible, to control.
NOTICE
The CG measurement should be made with
the completed airframe with all components
(batteries, servos, receiver, linkages, screws,
bolts, hardware, etc.) installed. Failure to do
so will result in inaccurate measurement.
BATTERY INSTALLATION
1. Push the spring-loaded battery latch tab back to release the battery hatch.
2. OPTIONAL- Apply a strip of adhesive-backed hook-and-loop fastener (not included) to the bottom of your battery and battery tray.
3. Press the battery to the center of the battery tray and secure with the provided hook-and-loop strap.
4. Reinstall the hatch, and confirm that the latch has positively engaged.
CAUTION
Always keep limbs clear from the propeller when the
battery is connected. After the ESC arms, the propeller
will rotate when the throttle is moved. Unlike an internal
combustion engine, electric motors apply more voltage
to counteract resistance, therefore any object that is
entangled in the propeller will be severely damaged
before the motor will stop
WARNING
When making adjustments to linkages, transmitter
settings, or the Aura 8 flight control system, remove
the propeller to guard against accidental spool up.
