Guide to Remote Control RC Model Helicopters: What Are 2, 3, 3.5, 4, and 6 Channel Helis? What Is a Gyro?
This guide will explain all the buzzwords and what to look for when buying this RC helicopter.Pro-Pro-Hobby RC helis is typically classified by blade length or engine size.For example, for pro-Hobby electric RC helis, you will often see the word \"level 450\" or \"size 450.
\\ \"This means that the length of the rotor blade is about 450 m (mm) and the diameter is about 10 cm, including the mounting point and the shaft.Similarly, the blade length of grade 700 or size is also 700mm.Due to different tip designs, the actual main blade sizes may vary slightly.
For the pro-With the light (I.
Nitro) engine (see \"by engine classification\") size category based on engine displacement (I.e.How big is the cylinder ).These engines are small.For example, the displacement of the \"30-stage\" Nitro engine is 0.3 CI, or 0.3 cubic inches.The Nitro engine can reach up to 90 (0.9 cubic inches ).They do not correspond directly to the main blade size, but here is a rough translation table (it can and often varies ).
There are three classification methods for RC helicopters: Engine, size and complexity.There are four types of power used by RC helis: Battery, Nitro, gas, and turbine.: The vast majority of RC helis are powered by rechargeable batteries.
The latest advances in lithium polymer batteries allow the storage of impressive power in a lightweight package, and RC heli manufacturers have used them to ship in such a small package for a few minutes of flight time.More complex battery-powered helis (micro or medium) can use replaceable battery packs (keep a couple of charged ones )!: The Nitro engine needs to be used for a long flight time.This type of engine is sometimes called a \"glowing engine\" because it does not use spark plugs but uses methanol, Nitro-Methane and oil.
But fuel is expensive.
These engines operate at extremely high rpm, up to 17000, and make very harsh screams when powered on.Some people call these \"gas engines\", which is not correct.: Some larger RC helicopters use a small 2-Gasoline engine.
These don\'t make as much noise as the Nitro engine.Gasoline is available almost anywhere and all you need is some 2-Cycle the oil with it.On the other hand, they are quite large for RC helis and usually only appear in full-and large-Size helis (see below for size classification ).
: In the ultimate of realism, you can\'t beat the micro turbo engine.These are very expensive, although the power they can generate with such a small engine is amazing (that\'s why they are used in real helicopters!) Parts are hard to find.As you can see from the picture at the beginning, the size of the RC helicopter (its \"scale\") can change a lot from 8-Inch mini helicopter (eSky Blade mCX 300) to 60-inches (5 ft!) Bergen is fearless.
It is generally divided into five classes.This is the typical \"toy\" RC heli you found in Brookstone and Radio Shack.It is about 6-A total of 12 inch, battery powered, in the palm of your hand.
Most of the RC helis will fall into this size category.Price from $15-125 depending on the degree of complexity and flight time (approximately 3-Fully charged for 8 minutes ).Electric-Wise, it\'s like class 100 to Class 150.
12-24 inch long, this model appears in the form of discounts in some hobby and toy stores.While a more complex version may use the smallest Nitro engine, most are battery-powered.The cost is between $30.300.This will be 200-350 class.24-The length is 48 inch, which is used by complex RC heli flyers to achieve those incredible stunts like upside down and barrel roll.
They usually carry 6-Channel control, often Nitro.Replace the battery with fuel-fueled.This is 400-550 class.The Nitro is about level 30-60.The length is 48 to 60 inch and can easily fly outdoors without being adversely affected by the wind.In fact, they are too big for you to even try to drive them indoors (exhaust gas from the engine can be a problem ).
Their quality is quite stable.
It\'s 600-Level 700 (90 if calculated by the size of the Nitro engine ).With a length of more than 60 inch (the size of the child), these models can easily reach an actual (non-proportional) speed of more than 100 miles/hour, and can easily be considered \"driverless\"These can be powered by gas, Nitro and even micro turbines.These are very serious hobby flyers and usually need some serious rallies.
Generally speaking, the more complex the helicopter is, the more control channels it has, but often with the increase in size.However, the recent micro-shrinking technology has led to four8-hailis Channelinch sizes.According to the complexity, there are three types of RC helicopters: toys, amateur flights and professional flights.
Toys are usually something you find in electronics and gadgets stores, like Best Buy or Brookstone.They cost between $25.75.They usually have 2-, 3-, or 3.5-Channel control and the latest generation have \\ \"gyro stability.\"The helicopter itself is in the palm of your hand.
Usually, the flight time of these RC helicopters is 3-8 minutes.Amateur RC helicopters usually fly from 12-The length is 18 inch or larger and has complete 4-channel control to support longer flight times and higher speeds.The price of these helicopters is $50.150, although some manufacturers are now producing microsized 6-channel birds.
Pro flight RC helis is a real helicopter miniatures model that is able to change the blade spacing (so use six control channels, usually Nitro, gas and even micro turbine engines ).They can perform flying and acrobatics.These fees range from $150 to $1000.Note that although the size itself is a general indicator, it is not a complete indicator of the toy.The WLToys V922 is a miniature balanced airspeedThere are fewer RC heli with only 10 inch long.
At first glance, it seems to be no different than $15.30 toys RC heli for sale in a toy shop but V922 is a complete toyfledged 6-RC heli ChannelIt costs about $100 and uses 2.4 GHz spread-Spectrum Technology (there are a lot of replacement parts available if you break something) and are fully able to put an upside down flight and other stunt flights.
On the other hand, you can get a 3.
5-Channel 26 toy heli-Inch size, even some 6-channel birds.There are three types of toys RC Helis: 2-channel, 3-Channels, as well as the latest variants, 3.5 channel.A 3-The Heli channel has functions such as speed control and gyro stability.
These RC helicopters are almost ready.
to-Out of the box (tf ).
Charge the helicopter itself and you can start flying.No assembly required.The 2-A 2-RC heli channel no more than 6-8 inch long, will fit your hand.Control is infrastructure.Red is the main one, so you can\'t fly outdoors (the lights will be combined with the controls ).
You also have to point the controller to the helicopter.Don\'t fly it behind a corner or obstacle.The range is limited to about 20-25 ft.The main remote control usually requires 6 to 8 AA batteries.There is a cable to charge the helicopter.
Due to the size of the helicopter (hence the battery), the flight time is limited to 3-5 minutes.Recharge time 5-10 minutes.There may be flashing lights indicating full power.There are only two controls for this RC heli: Throttle (Z-axis up-Down) and turn (I.
This version usually has two rotors: the main rotor at the top and the tail rotor pointing to the side.(See example).There are two models.Rotate the main rotor instead of just one, but both are driven by the same motor.This version can only fly up and down and left/right.
The vertical Z-Control the movement of the shaft by changing the speed of the main rotor.The helicopter turns left/right by changing the tail paddle speed.The helicopter body has a slight nose wing-heavy.
This gives the helicopter a constant, slow, forward speed.You can adjust the speed slightly by adding a little weight to the nose of the helicopter, but don\'t overdo it.The helicopter was designed as a disposable toy.
The general rotor is plastic and the body is foam.If you crash it, expect it to break, especially when it falls from a height.As these are disposable, there is no replacement part (although there may be a replacement main rotor for some radio shed models ).
With the advent of better chips, most of them have gone extinct, except for the unusual \"novelty\" Helicopters of shape or theme.Note: usually only one can fly in the room at a time, because the infrared signal is not coded to a specific \"channel\", the signal may be confused.Pros: Easy to handle, cheap to start ($15-Because these are all disposable, so look for a cheap price.
The 3-The 3-The RC helis channel is usually for you, no more than 6-8 inch long, almost as big as number 2channel birds.Although some slightly larger can go 12 inch or even longer.Control is infrastructure.Red is the main one, so you can\'t fly outdoors (the lights will be combined with the controls ).
You also have to point the controller to the helicopter and don\'t drive it around the corner or behind an obstacle.The range is limited to about 30 feet.Usually you have the main remote control and you need to put a lot of AA batteries (6 to 8 knots ).You released a cable from the remote to charge the helicopter with a small port on the side of the helicopteroff switch.
There are 3 small-5 minutes flight time for full charge.The larger may be up to 10 minutes.The 3-The channel RC helis provides a variable forward speed by changing the rotor arrangement.They have two counters.Rotate the main rotor, one clockwise and the other counter clockwiseControlled by two independent motors.
There is a third rotor at the tail (controlled by a 3rd Motor), but this rotor points up instead of the sideLike 2-channel birds.The 3-The channel RC helis has more freedom of movement as it now has a variable forward speed instead of 2-channel birds.Vertical rise and fall are still controlled by the main rotor.
By adding/subtracting the RPM of the two main rotors, heli will rise and fall.By adding RPM only to one rotor, turning inertia causes the heli body to rotate in the opposite direction, allowing heli to rotate left or right.Finally, by rotating the tail rotor, the tail can be pulled up to cause forward motion (or pushed down to fly back ).
One motor is controlled per channel.
These helicopters look cool and relatively flexible, but they can\'t fly sideways or do what a real helicopter can do.On the edge of the show, the helicopter was not stable.It is very likely that the tail oars are so large that the helicopter is flipped over and causing a collision.
Construction-It is wise that the cheap birds are still made of plastic and foam shells, even though the price is higher --The metal skeleton and various replacement parts have high quality.Look for one that has a replacement part or is already in the box.The rotor will indeed be beaten.The 3-Strait birds are the current \"standards\", although they are quickly replaced by the updated \"3.
Channel 5 \\ \"bird.
You can find 3 channel birds online for about $25, and retail for $40.NOTE: Some 3-Channel birds may allow different \"control channels\" to be set up so that the two birds can play in the same room.If you don\'t think it\'s a feature, let\'s say they\'re \"lonely\", I.
There is only one room.
5-The RC helis channel is basically the same as the birds in the 3 channels physically.They usually fit your hands as they are no more than 6-8 inch long (some slightly larger can reach 12-18 inch, like 26-Double Horse ).The control is usually belowRed so you can\'t fly outdoors (the light interferes with the controls ).
You also have to point the controller to the helicopter and don\'t drive it around the corner or behind an obstacle.The range is limited to about 30 feet.Some of the larger ones may use 2.4 GHz radio controls and their large size allow them to fly outdoors, although the range is still 50-75 ft.Some of the most recent variants use WiFi control and register as a device on the WiFi network.
Depending on your local WiFi environment, this gives you more scope.Normally, 6 to 8 AA batteries are required for the main remote control..You released a cable from the remote, using on-off switch.
There are 3 small-Full charge for 5 minutes flight time.The larger may be up to 20 minutes.The latest may have a micro usb port for charging, large may even have an exchange-The battery is dead.Instead of using a regular remote control, some of the most recent models are equipped with an infrared transmitter that you can plug into your smartphone and control through the app.
However, this method is not accurate and is not recommended.Gyro/stable /.In response to concerns about unstable 3-channel birds, toy manufacturers have added tilt sensors or \"gyro\" (the same sensor in a smartphone) for the control logic of birds, it acts as a spoiler of input.For example, the gyro feels that the cutter is already walking towards the nose --Falling to 30 degrees will lead to a helicopter crash.
It will stop any further tail rotor command and pull the tail up.However, limiting controls is frustrating for more experienced users, so the manufacturer adds two sets of parameters.In \"amateur\" or \"low\"In speed mode, the controls are covered by a gyro at a lower level, limiting your mobility.
This also reduces the speed and potential damage.There is an option to switch to professional or advancedSpeed mode, which limits control at a higher level, gives players a higher level of operability.High vs for this option.Low speed is called 0.Channel 5, as a \"feature\", makes them better than 3-channel birds.
Note: some better 3.
5 Channel birds can be set to different control channels to allow more than one bird in the same room at the same time.Some of the 3.The 5-Channel bird may have special features, such as the actual launch of small plastic missiles, or allow two helicopters on different control channels to \"beat dogs\" and \"shoot\" each other \".The on-board sensor records hits, the victim drops 3 feet and the rotation is out of control.
Advantages: more operability, more stability, often replace parts during maintenance.Cons: Still not a real helicopter flight, short flight time, more complicated than ever before.Wireless, not infrared.red control.There are usually two ways to do this: ToysGrade, hobby grade.
Recent advances in battery and manufacturing have enabled toy manufacturers to pass on 3-channel bird.However, this is just a kludge as it is not close to the real helicopter flight.To fly horizontally, you just have the side Motor do a differential thrust: one up and the other down, which pushes the whole thing one and vice versa.
The rest of the helicopter is 3-the samechannel birds.These are toy-Grade helicopters with IR control, usually without replaceable components.That\'s it once they break.Hobby-Some manufacturers have expanded their models in order to attract more complex viewers who want a more realistic flight experience.
Usually, the fourth grade-Channel bird 18-The length of the single main rotor is 24 inch.(There are exceptions, like E-The Flite Blade series, which is only 8 inch long, is not a toy.You can hurt someone if you hit him.The blade and body can cut people.Don\'t fly indoors unless it\'s a lot of space, like a gym.
They use 2.
4 GHz radio control, so the range is up to 80 feet.The real helicopter dynamically adjusts the \"spacing\" of the main rotor (or the amount of air the blade passes through) and uses it to control the way it is flown.In order to fly forward, the blade is adjusted, so the \"second half\" of the rotor disk produces more lift (higher spacing) than the first half ).
To fly to the left without turning, the \"right half\" of the rotor disc is adjusted to have more lift than the left.4-this fine control is not possibleChannel birds, because their main rotors are \"fixed spacing\", do not change like a real helicopter.Instead, they have other tricks to achieve sideslip: move the rotor itself through a set of servo systems located on the main rotor.
By slightly tilting the main rotor, the bird can move forward or backward and slide left and right.There\'s another kind of 4-Channel hobby birdAxial type with two main rotorsRotate (one clockwise and the other counter clockwise)clockwise).These are very stable because both rotors act as \"gyro\" of the stable aircraft \".
But as a result, this model is very different from the fixed flight properties.pitch single-main-Rotor 4 channel hobby birds because they don\'t have tail oars.These 4-Straits bird is a hobby, priced anywhere from $50200.
However, they are carefully manufactured parts with all replaceable and upgradeable parts.Servo system, motor, rotor, gyro, antenna, even battery pack.Okay, about $120.If you go this way, it\'s better to buy a kit, a training gear landing gear, quite a few replacement parts, an extra battery and charger.
You can also consider a PC \"coach\" where you practice flying on your PC before you try with your hobby RC heli.Disadvantages: four degrees of freedom means more training is needed.There is still no complete operability.Looking for: metal frame, metal rotor mechanism, 2.
4 GHz radio frequency control, Spectrum-spectrum anti-\"Professional\" hobby RC helis features all 6-Channel Control, which means full 6-Freedom.The helicopters cost up to $1,000 and are able to perform a variety of acrobatic movements, including upside down flights, barrel rolls, etc.The high-The final battery will use nitro fuel, not just the regular one.
These 6-Channel pro hobby birds simulates the rotor mechanism of a real helicopter by allowing a single main rotor blade to change its spacing (pushing air more or less) while rotating.The rotor mechanism will be much more complex than the toy model, but the result is a more operational and real helicopter flight.Older generation birds have an additional \"flybar\" as a balancer/Gyro, although the latest generation does not have flybar.
Also, not a 2-Bade main rotor, some 3-The design of Bladed has emerged, making them look more and more like a real helicopter than just an approximation.You can see the eSky HoneyBee CT video below, which is a threeblade, flybar-less design.It looks like a static model of a helicopter, but it\'s not flying RC helicopters.
Performance difference between 4-Channels and 6-Channel hobby heli is day and night.Look at a 6-Channel birds can do it.Keep in mind that this could be a $750 bird with custom parts, NitroEngine and the like, but it\'s still a bird you can get from the shelves.In this video, you\'ll see this heli doing the bucket roll, right-Upside Down, loop, Immelman climbing and diving, nose-Flying sideways, etc.
Watch and be surprised.
Hobbies 6-The RC heli channel needs a bit of experience and you shouldn\'t put it in right away.There are some RC helis available on the market in 4-and 6-Channel operation.But I still suggest you check out Xheli.Com, it has a lot of tutorial videos, tuning and tuning techniques, etc.
On the other hand, things like the V922 are perfectly capable of inverted flights and other stunt flights, although the \"micro\" scale is much lower when flying indoors.There are many design innovations worth studying here.The first and most famous is the parrot\'s AR Drone.
Sold through Sharper Image, it is usually controlled by an Android or iOS device with app and on-board WiFi.There are cameras in the car.Latest version, AR.Drone 2.0, there is a 720 p HD camera that can take better photos from high places.You can fly indoors with the \"bumper\" housing to protect the rotor or fly outdoors without making it lighter.
Of course, it\'s a bit expensive.
For those who think AR.
The drone is a bit too rich, now the WLToys V959 quad-core camera.This model is a cheaper and smaller version of AR.Drone.The camera is not as good as the camera records on the microSD card and there is no transmitter (you do have a reader ).
The camera is removable, according to the comments, and you can purchase additional items such as winches, plastic missiles, and even a micro-spray gun fired remotely.Square planes are available in various sizes and they are very stable due to their squarerotor nature.However, their battery life may be better.
Some upscale manufacturers have introduced toy-like controllers through WiFi and smartphone IR modules.AR.The drone was the first to introduce WiFi control.Basically you pair your smartphone (Android or iPhone) WiFi with the AR Drone, which acts as a limited hotspot, which will receive a control signal and send back the video via the same channelYour compatible app will solve this problem.
This control scheme was borrowed by some manufacturers for their simpler RC helis.The controller is done by touchScreen Pad on smartphone.There has been another variant recently using Bluetooth instead of WiFi, but that\'s the same idea.
Some manufacturers, look better to distinguish themselvesTechnology, double throwAdhere to the RC, including a micro infrared transmitter plugged into the smartphone headphone jack.The transmitter sends a control signal but is the same as the one sent by the RC controller.You can also run an app that sends infrared signals through the screen control panel on your smartphone.
I don\'t like smartphone controls because they don\'t feel right.The controller does not have enough physical feedback if you use the touch screen.It feels too gimmicky.What should you buy?Overall I do not recommend buying any \"toy\" MicroEven the four channels have RC helis of the size.
They can be entertained indoors or buzzing with cats or dogs in your entertainment, but not anymore.Once they have crashed a few times, they are basically finished.It is expected that the motor will not last too long, and the battery that continues to charge and discharge will wear out very quickly.
If you get one in this category, don\'t buy those pharmacy specials.Buy good parts with lots of replacement parts.The WLToys V922 micro Heli mentioned earlier comes with several spare parts and comes with a replaceable battery (and rechargeable battery) for 15 minutes or longer flight time, charging for one hour.
You should get a \"mini\" or \"middle\" for the proper flying hobby\"sized\\\" 4-The RC heli channel is your starter.You can learn how to use one of the flights correctly and then transition to the right 6-RC heli ChannelYou will spend more money at the beginning, but with enough parts, you can maintain and keep your heli running without buying a replacement every few months.Most people suggest that you should get a 600 or 700 class helicopter to practice as these can easily fly indoors and outdoors.
In my opinion, the best way to start is to buy the eSky training kit for around $25.This gives you a copy of the usb rc controller so you can practice controlling the RC helicopter or aircraft and crash as you like.Once you\'re sure you can control a beast like this, go and buy the real thing.
Finally, I hope you have found a quick guide to RC helicopters, which helps you to make a decision on your purchase.Have fun outside
