(5) Safe operation
Please fly your helicopter according to your physical status and
flight skills. Fatigue, listlessness and mis-operation will increase the
possibilities of accidental hazard.
(6) Keep away from high-speed rotating parts
Please keep the spinning blades of both main rotor and tail rotor
away from the pilot, people and other objects.
(7) Protect from heat
An RC helicopter is made from metal, fiber, plastic and electronic
components, etc. Please keep away from heat and sunshine in order to
avoid distortion, even damage, caused by high temperatures.
2.3 Attention before flight
(1) Ensure the battery packs of both transmitter and receiver are fully charged (saturated).
(2) Ensure both the throttle stick and the throttle trim of your transmitter stay at the lowest positions before
operation.
(3) Please strictly obey the order of turn-on and turn-off before operation. When starting your flight, please turn
on your transmitter first, and connect the power cable of your helicopter last.
When finishing your flight, please disconnect the power cable of your helicopter first, and turn off your
transmitter last.
(4) An upset in the order of connection may cause your helicopter to loose control. Please cultivate a correct
habit of turn-on and turn-off.
(5) Ensure the directions and actions which servos execute transmitter commands are correct and smooth,
respectively. Using a broken servo will result in unforeseen dangers.
(6) Check there are no missing or loose screws and nuts, no unassembled or damaged parts. Carefully check the
main blades have no defects, especially the position close to the main blade connector. Broken or unassembled
parts will have an effect on the flight performance, and will cause unforeseen potential dangers.
(7) Check all the connections between ball linkage and ball. Loose linkages and balls should be changed.
Loose connection between linkage and ball will have an effect on the flight performance, even lose control.
(8) Assure there are solid connections between the power cables of battery pack and motors. Continuous
vibrations in flight may loosen the battery tie-ins.
