Walkera Dragonfly 68B Pro 7CH All Metral Structure CCPM 3D Electric RC Helicopter w/ Brushless Motor RTF

Features: 1). NOR collective pitch structure make perfect 3D maneuvers such as roll, inverted, and swoop flights. 2). 68#B/69#B design of metal tail, metal swash plate and metal rotor head is of legerity, innovation, precise and stability. The autorotation landing system, made of high quality one-way bearing, maximally protects your helicopter from damage . 3). Highly efficient bevel wheel design is used in mesh between main gear and motor gear. 4). 69# series tail blades driven by axis provide easy adjustment, stable flight, and prompt reaction. 5). 68# series tail blades driven by belt provide easy adjustment, stable flight, and low noise. 6). Outer-rotor motor as the main power is powerful and makes the flight much stable. 7). 7-ch transmitter PCM701 with adjustable PIT parameter, throttle curve, and servo exponential function. 8).Walkera 68B Full Metal 3D Electric RC Helicopter
