syma s009g commodities: APACHE helicopter of a simulation of a high degree of design concept and infrared remote control technology, it is powered by the coaxial counter-rotating blade, dual-motor system that uses electronic spinner, regulation of the stability of the aircraft, full The machine easy removal and installation, convenient adjustment and maintenance of the helicopter, but also more beautiful and practical. Very stable in flight performance, flight action beyond the imagination of a smooth and accurate, can easily make the hover and various air routes. A 3.7V lithium polymer battery pack helicopter flight time is longer.
Of the products, with beautiful, stable flight, excellent material, simple operation, can be hand-held take-off or ground takeoff.
The product design structure is reasonable and scientific, the selection of materials super anti-wrestling, fall prevention.
Easy to operate, easy to learn (with detailed Chinese Illustrated Guide): suitable for children over 3 years of age or adult model enthusiasts.
Anywhere any flight, to exercise the child's sense of direction ability, the ability to think, but also to cultivate children's interest in aeromodelling.
This product has been CE, ROHS, 6P, ASTM, HR4040 certificate, safe and reliable, the children themselves charge, parents can rest assured.
The factors affecting the life time including: charging impact: according to the instructions on the charging time is sufficient and mobile phone batteries generally need about 4-5 times charge and discharge can only be fully achieved active
operating technology impact: novice, such as the ups and downs next flight will greatly shorten the flight time is recommended to practice. extend the flight time reaches a stable flight
weather: extreme weather will affect the battery capacity (such as high temperature and low temperature. do not believe Baidu look see)
battery life impact: the general life of lithium batteries in about 300-500 times with the time and the frequency of use of capacity will gradually decline .
battery damage effects: such as the battery falls from a height caused internal damage. overcharge overdischarge are likely to cause capacity fewer or even damaged.
