A radio-controlled helicopter, especially when it offers a realistic look, it's still beautiful. WLtoys the manufacturer has not given up the helicopters for the benefit of multirotors, as evidenced by the V931, which takes up the look of the AS350 Ecureuil Aerospatiale / Eurocopter / Airbus Industries.
The V931 flybarless rc helicopter is distinguished with a three-blade rotor unusual, variable pitch driven by a brushless motor 11000 Kv and a battery of 3.7V 500 mAh 25C. We tested the V977 (see here), a model of stability in gyroscope 6 axis mode: it works on the same principle. For aerobatics 3D gyroscope passes in 3 axes. WLtoys states that the flight is about 5 minutes, the weight of the device is 77.5 grams (with battery), for a rotor diameter of 24.4 cm and a length of 23.8 cm . The tail rotor is meanwhile brushed type. The radio is available in mode 1 or 2 with the purchase - but this model, anyway, is disengaged by pushing a button. The V931 is available at Banggood, which costs you $ 119.99.
Additionally, if you you need some of the rc drones parts, you could search at Banggood, which is one of the wholesale platform to provide you the low prices. Such as, helicopter brushless motor, motor mount quadcopter, quadcopter motor set, etc.
