Dragonfly (radio controlled helicopter)

Dragonfly ( “Dragonfly” in English ) is a series of radio controlled helicopters electric manufactured in China by Walkera . It is a small model and low price. There are Dragonfly 22 , 35 , 36 , 40 , 60 , 37 , 5 # 4 , 39 , 45 , 53 and 4 . The radio control controls the power of the engine, the inclination of the helicopter to the right, left, forward, backward, and rotation on itself.

Model 4 is simple and effective because it does not control the inclination of the blades . The models 35 , 36 , 40 , 45 have a variable slope of the blades that must be controlled: this is called the variable pitch or not collective . The reclining blades are balsa covered with plastic and are quite fragile. Model 4 has soft plastic blades, which prevents them from breaking. It is also one of the most widespread, both in its strength and low cost. It is particularly suitable for beginners who wish to learn about helicoptersnot fixed (or FP) at a reasonable price.
