Center of Gravity

Check the position of the center of gravity (CG) as shown in the diagram, 70-78mm back from the leading edge of the wing at the fuselage. Setting the correct CG is essential for successful ight.

70~78mm

Before Every Flight

To help avoid ight accidents, ground inspections should be performed prior to every ight.

• Ensure all screws are secure, the servo arms and horns are properly connected and the wing is properly secured.

• Install the recommended battery (not included), adjusting the placement to ensure the center of gravity is correct, as recommended in the manual.

• Ensure both the ight battery and the transmitter battery are undamaged and fully charged.

• Ensure the transmitter throttle stick is at the lowest position prior to powering on the aircraft.

• After the aircraft is powered on, perform a control surface check to ensure both proper travel and the surfaces return to neutral when the transmitter sticks are returned to neutral.

• With all body parts and loose items away from the propeller and the aircraft securely held, gently push the throttle up to check for correct rotation of the propeller.

• For inexperienced pilots, always seek assistance from an experienced pilot.

Flight Time

Based on the specications of the recommended battery (not included), we suggest setting a ight timer to 4 minutes of powered ight. The actual ight time will vary depending on the battery used, aircraft weight, ight conditions and the ying style of the pilot. When the timer expires, do not y too far downwind to prevent not being able to return safely. Land the aircraft and recharge the battery.

Flying Tips

• We suggest you practice your ying skills on an RC ight simulator before attempting to y this model.

• The rst ights should be made at an altitude above 50 meters at approximately half throttle, until you become familiar with the ight characteristics of the aircraft.

• Always take off and land into the wind.

• Always y the aircraft in front of you. Do not y the aircraft directly above your head or behind yourself.
