This cheap rc helicopter is our new launched powerful Walkera 5-4Q4 RC coaxial helicopter, which is very easy to fly, and its distinct stability in the air makes it perfect new RC helicopter players. The white and blue color cover gives you pure and fresh feelings. At the bottom locates the undercarriage with three style wheel design, which will add to the enjoyment of flying this superb electric helicopter. The main blades are made of high tenacity materials that are able to bear impacts. But Walkear 5-4Q4 still comes with 4 main rotor blade replacements in case of accidents. Flash lights not only make it shining and beautiful, but also make night flying possible.
Next goes to its transmitter. Walkera 5-4Q4 cheap rc helicopter uses frequency hopping on the 2.4GHz band, instead of the various frequencies in the lower MHz ranges. Thus, signal strength is much better and control distance of the transmitter is much wider than traditional ones. Furthermore, on the back of the transmitter there is a simulator jack, which enables you to connect the transmitter with the computer through the included connecting cable. This cheap rc helicopter is an excellent idea if you're serious about flying radio control helicopters. You can learn how to control in complete safety and rapid learning curve, without risking crashing your actual model.
Moreover, the built-in gyro senses any rotational movement of the cheap rc helicopter that isn't a result of a signal to the receiver and it makes fine adjustments to the tail rotor speed or blade pitch to suit the torque force at that precise moment, hence dampening out any unwanted yaw. It makes these calculations and corrections at lightning speed, so much so that you won't notice anything other than a stable helicopter!
Let Walkera 5-4Q4 bring you to the great fun of flying RC helicopter in the Sky. Let your dreams fly and you will own your own space in the sky sooner or later.
