Rc Coaxial Helicopter - The disagreement between Toys And The Rest

When you start out studying to fly radio controlled model helicopters you are immediately confronted by a multitude of choices. One of the first things you will consideration is that you get two basic types of radio controlled helicopters to choose from namely those with a single rotor and those with a duplicate set of main rotors, the coaxial Rc helicopter.

Within each of those groups you will also find quite a few variations, which may make slight sense at first glance.

I will couple here on the coaxial Rc helicopter and feature the differences within this group, and mention some of the benefits of studying your Rc helicopter controls on this type of radio controlled model helicopter.

Rc Coaxial Helicopter - The disagreement between Toys And The Rest

When I started finding nearby you could find a Rc helicopter in most toy shops. One of the favorite types you will find in toy shops is the configuration with a horizontal tail rotor driven by a tiny galvanic motor sitting right under the tail rotor.

Although this type of Rc helicopter - some of the smaller ones are undoubtedly infra-red controlled - can be flown successfully, it has fairly slight maneuverability. The transmit and backward movements are controlled by the horizontal tail rotor: rotating in one direction will lift the tail up and push the heli forward. Rotating in the other direction will push the tail down and drag the heli backwards.

Turning this heli happens by pointing the nose in the direction you want to go, and this is controlled by the variation in rotating speeds of the two main rotors. The heli will turn in the rotational direction of the slower rotor.

The drawback with this horizontal tail rotor arrangement? This heli can't bank in a turn as would be indispensable in a faster turn. I also found control difficulties as the tail wants to "overtake" the main rotor in transmit flight. It was much easier to fly backwards as the tail rotor would essentially pull the rest of the motor along.

I tried my level best, but I couldn't coax any serious controlled flight out of my toy coaxial helicopter, and I essentially wrote it off within days of putting in serious attempt to control it properly. The toy shop also didn't carry spares!

So, what comes next?

I decided to give the toy shop a rest and popped into the local hobby shop. There the guys showed me a separate kind of coaxial Rc helicopter, a much more serious motor with a "real life" swash plate. Without going into a lot of detail, the swash plate makes it possible for the heli to bank in any direction by tilting the whole rotor (the lowest one of the two counter-rotating main rotors) on command from the radio transmitter.

Because of that swash plate this coaxial heli doesn't use a tail rotor to move it in a direction.

I bought this hobby grade heli - a 'Nine Eagles Swordfish' - and found it amazingly maneuverable, and in a short time I managed to learn the basics of Rc helicopter controls, all the while having a lot of fun both indoors and outside!

Radio Controlled Helicopters - What's the variation between 2 Channels, 3, 4, 5 and 6 Channels?

All radio controlled helicopter enthusiasts will tell you that flying Rc helicopters is the most tantalizing and thrilling of all Rc models. Cars, trucks, tanks, boats and robots are all minute to forward/backward and left/right movement but radio controlled helicopters can have full technicolor, surround-sound,3D maneuverability. The only limitation to your exhilaration and flying satisfaction is your skill, the space available and the sophistication of your Rc helicopter model.

So what is it exactly that enables your heli to achieve complex aerial acrobatics?

In short, it's the amount of channels that can be controlled by you - the more you have, the greater the maneuverability of your Rc helicopter.

Radio Controlled Helicopters - What's the variation between 2 Channels, 3, 4, 5 and 6 Channels?

But don't be fooled into reasoning that more is better. Flying a model helicopter is every bit as complex and skillful as the flying the real thing. Just because your heli is smaller in scale doesn't mean that the laws of aerodynamics change! To achieve prosperous flight, all criteria remain the same. However, flying a model does have the benefit of being able to start with a basic set of controls and work your way upward to the Full Monty and this is achieved by mastering an addition amount of channels.

But first, you will need to understand that each channel controls a cut off servo mechanism in your model. And for those of us who find it helpful to understand how a thing works, it's beneficial to know that a servo is a mechanical gismo that controls the movement of an element by 'pushing' it with a lever. You can operate the degree of 'push' this lever exerts on a servo from the controls on your transmitter handset. The greater the servo's 'push' the bigger the resulting movement of the element it is acting on. So, to move the angle of the tail rotor, for example, you need a channel to operate the tail servo.

So, as each transported element on an Rc helicopter requires its own servo, you will also need an extra channel for each one. By addition your ability to fine-tune the interaction of each servo via the channel controls on your handset, you will be able to produce an increasingly wide range of aerial movements for your radio controlled helicopter.

So here's a basic list of the differences in the middle of the numbers of channels on a radio controlled helicopter:

• 2 Channels provide you with the ability to operate two servo mechanisms, giving you the ability to operate movement up and down (rotor blade speed) & left and right, (rear rotor, directional controls).




• 3 channels give you the two movement controls, above, but with the further operate of tantalizing backwards and forwards (cyclic control).




• 4 channels give operate over the throttle, elevator, aileron, rudder, enhancing on the maneuverability of the above, fixed pitch controls.



• 5 channels are rarely found, giving way to the more base 6 channel model. These further channels give skilled flyers the ability to achieve true, 3D aerial movements by adding public pitch and gyro gain operate into the mix.

It can all get very complicated!

So which is the best choice for you? Well, if you are just beginning out with radio controlled helicopters, stick to the 2 channel models at first. Learn to expert the basic movements first before progressing through the ranks, right up to the impressive but tantalizing 6 channel models. Whatever you decide, have fun with your Rc helicopter, fly safely and enjoy enhancing your flying skills!

When you start out studying to fly radio controlled model helicopters you are immediately confronted by a multitude of choices. One of the first things you will observation is that you get two basic types of radio controlled helicopters to select from namely those with a singular rotor and those with a duplicate set of main rotors, the coaxial Rc helicopter.

Within each of those groups you will also find quite a few variations, which may make puny sense at first glance.
