Take off and landing tips
3. Never exceed 3 minutes to fly with the maximum power others.
4. Never exceed the limited flying weight.
1. Remove and inspect contents.
2. Charge fl ight battery.
3. Read this instruction manual thoroughly.
4. Fully assemble model.
5. Install the flight battery in the aircraft ( once it has been fully charged ).
6. Bind aircraft to your transmitter.
7. Make sure linkages move freely.
8. Make sure the rubber ring has been properly slide on the clevis.
9. Perform the Control Direction Test with the transmitter.
10. Adjust light controls and transmitter.
11. Perform a radio system Range Check.
12. Find a safe and open area.
Please read the following instructions and fully understand it.
1. Do not fly in strong wind or bad weather.
2. Never fly the model in crowded areas, where there are lots of people, automoblies on the
road or power lines overhead . Also do not to fly around the airport. Please make yourself
enough room for the flying and operating, as the plane can travel at high speed. Remember
you are responsible for the safety of others.
3. Children under the age of 12 should have an adult guide. Never recommend for the children
under the age of 14.
4. Never leave the charger in wet conditions.
5. The A1 is made from PA and polythene which are tinder. When it meets the heat,
transfiguration can easily happen, so you must keep it away from heat.
6. Do not attempt to catch the A1 while flying, please do not touch the propeller.
7. Never leave this system unattended around children with battery in the unit, as injury may
be caused due to children's turning on the transmitter or the plane.
8. During the preparation for the flight, please remember to turn on the transmitter before
connecting the battery pack.
9. Close the throttle on the transmitter before connecting battery otherwise the motor may operate.
Battery Selection and Installation.
1. We recommend the 1.1V 1800mAh 25C Li-Po battery.
2. If using another battery, the battery must be at least a 1.1V 1800mAh 25C battery.
3. Your battery should be approximately the same capacity ,dimension and wight as the
1.1V 1800mAh 25C Li-Po battery to fit in the fuselage without changing the center of gravity
a large amount.
Note: Because of the weather and ground,please connect the UBEC at least in a distance
5cm far away from the receiver to avoid the electromagnetic interference.
