How The Coaxial Remote Control Helicopters Work?

. These double-bladed helicopters are most often accredited with bringing hordes of new enthusiast into the world of RC aviation. Its popularity stems from its stability when in flight, making it relatively easier to master when it is compared to is single rotor counterpart. It is also very predictable enough, making it able to fly within the compounds of ones home. Aside from this, it is also available for purchase in ready to fly kits.

The stability of coaxial remote control helicopters comes from its ability to eliminate the need for the tail rotor completely. This is because the coaxial helicopter line has two rotors placed on top of the other, and rotating in opposite directions. The effect of this set up is that the torque generated by each of the rotor cancels out the other, and when such a feat is accomplished and coupled with the two rotors lift, it complements each other and results in unbelievable stability and hovering ability. Because it is known that hovering is one of the main components of any flight, saying that a helicopter is easier to hover is almost the same as saying that the helicopter is easier to fly. Controlling the yaw in this setup also becomes only a matter of slowing or speeding up one of the two rotors. Another added bonus to this set up is that it does not require the presence or use of a gyro, which means that there is a lesser amount of tinkering needed for the helicopter to work.

Although the coaxial remote control helicopters receive a lot of praise, it is not without faults. The first fault that you will surely notice if you have this type of helicopter is that in order for the helicopter to take off, the speed of the two rotor blades must be exactly equal. The coaxial helicopter is so dependent on the synchronicity of the blades that even the slightest deviation of the speed on one blade from the other is extremely detrimental to the helicopter. The two motors simply have to be in their most pristine state if it is to function properly. If the speeds on both blades are different, the helicopter will not be able to lift off of the ground and just spin wildly. Another down for this type of helicopter is that the stability comes with the price of easy maneuverability. For all its stability while on the air, the coaxial are very slow and sometimes even unresponsive. Nevertheless, the most con in getting the coaxial helicopter is that the two blades sometimes bite each other while in flight when extreme cyclic controls are put into play.

All in all, the coaxial remote control helicopters are very good for beginners, and are very much advisable for flying indoors. However, if you want more maneuverability in your helicopter, then opt to get another type.
