The hobby of flying radio control helicopters has grown quite popular over the past few years. This is generally because people are now aware of how enjoyable it can be to fly these model aircraft. In this article, as well as over the next few, we will be looking at the main types of electric helicopters now available; coaxial, fixed pitch (FP) and collective pitch (CP).
As many people are now taking up this interest, it is always good to learn the basics and take in as much information as possible about the types of choppers out there. We will now look at the three main groups of helicopter you can buy, starting with coaxial electric models.
Coaxial, or dual-rotor helicopters, have two sets of main rotors instead of the usual one (as seen on conventional helicopters) along with a tail rotor. These two rotors are placed one above the other with no need for a tail rotor.
With some coaxial helicopters, the two main rotor blades spin in completely opposite directions and cancels out the torque. Therefore, there is no need for a tail rotor to provide a counter to this. As a result, these choppers are very stable in the air and easier to master.
You can get a decent coaxial helicopter in a ready-to-fly package and start learning to fly one right away.
