Walkera Dragonfly V450D03 6CH Flybarless CCPM RC Helicopter RTF 2.4GHz w/ Devo 7 TX

DESCRIPTION

The Lite Version of the Flagship V450D01 Helicopter – the Walkera V450D03 Flybarless Helicopter. The Walkera factory did produce 450 class helicopters, they uses high end material like carbon fiber and CNC aluminum, packed with high tech 6-Axis gyro and digital metal gear servos. They revised it a few times, updated some electronics and V450D01 became the flagship model in their product line. However the materials needs some cost. So to make a more remarkable sales, the factory tried to make a 450 class heli with lower cost, that’s the V450D03. But don’t worry, this big helicopter is not a “downgraded” one, it keeps the great electronics like the brushless motor, the digital metal gear servo, and the 6-axis gyro. Just changed some materials, for example using carbon fiber reinforced plastics, this already cuts much of the cost. So you’ll find the price and the performance both good, it’s super worthy. Not only producing high cost quality helicopters, but also suits the market needs.                                                                                                                                                                                             The helicopter is light, it’s light weight makes it more direct control and more agility. Also a point to notice is the precision on the rotor head and tail assembly, they have ZERO gaps, nothing is loosen. Flying the V450D03 is easy, because it has a responsive chassis and very direct control, thanks to the use of Plastic, this is what makes the V450D03 so special. You may say Plastic Heli is cheaper than Carbon Fiber + Metal Heli, well, not exactly, because now-a-days plastic industry has improved a lot, they mix composite material into the plastic, sometimes they are stronger and lighter. Besides, it’s no cheap, because Plastic Parts need molding, this molding process cost a lot more than you think, Walkera has taken a bold move. Plastic gives the chassis elasticity, you can actually feel this when you are flying, it feels smoother over that Carbon Fiber and Aluminum helis, that’s what makes the V450D03 so cool.                                              Different from the V450D01, almost all material used is different. For the V450D01 it is Carbon Fiber + Metal, and for the V450D03, it’s almost all plastics. And they have different design in structure, keeps all the best electronics but with better arrangement on them.                                                                                                                                                                                                 No matter you are a Beginners or Expert, you will love the V450D03. It has the Stability, thanks to 6-Axis Gyro, it has the Agility and Handling, thanks to the well made Plastic parts, the brushless power system and digital metal gear servos. So if you are a beginner with experience on Co-Axial and Single Rotor Helis, this is your best choice for outdoor heli (Remember to put training kit on the landing skids to start practicing).                                                                                                                                                                                                                                    

Same as other newer Walkera Models, the Super CP is capable of online update, with the updater UP02 and UP02A adaptor (Purchase Seperately).

Quadcopter: 3 Things you Need to Know

drone12

Helicopters, Drones, Airplanes, Quadcopters? What does it all mean? This week we’re clearing the confusion on the very popular quadcopter. This has got to be one of the newest, trendiest, and most popular kinds of drone for sale. If you’re interested, we’ll bring you three things you must know about quadcopters.

First things first, what the heck is a quadcopter?

No need for confusion here, a quadcopter is simply an “unmanned helicopter having four motors.” Most hobby sites, like ours, also use the term to refer to any RC Drone with four motors. Want the breakdown on all other types of multicopters? Heres the list:

Helicopter: 1 motor                                                                                                                                                       copter35                                       Bicopter: 2 motors        copter36 Tricopter: 3 motors copter37  Quadcopter: 4 motors drone13 Pentacopter: 5 motors drone14 Hexacopters: 6 motors drone15 Octocopter: 8 motors drone16

The multicopter phenomenon currently ends with a Drone/Helicopter with 8 motors (which is plenty).

What you need to know if you purchase a quadcopter:

Well, first off, congratulations on your new quadcopter! We sincerely hope you enjoy it. Just like becoming a new driver, you’ll need to know a few things before you fly your drone.

1. Drone Registration: It is a mandatory thing to do for all drones weighing .55 pounds and less than 55 pounds must be registered to the FAA. Don’t worry, it won’t cost you much, but you must do it before flying your drone.

2. Locate your Power Switch: Sorry if we sound like Captain Obvious here, but you’d be surprised, sometimes it is hard to find this tiny switch. Once you do find it, turn your quadcopter on to see if it had any charge. Test your controller by pressing buttons to make sure that your quadcopter and remote are in sync. If there is no signal, refer to your owners manual to sync both of your devices.

3. Charge Time:  All quadcopters are different, but knowing your quadcopter’s charge time is very important. Find out the time LIMIT. Do not exceed your charging limit because you WILL burn out your battery and have to purchase a new one.

4. Flight time: The more money you spend on your quadcopter, the longer you’ll be in the air. When a quadcopter is about to die, it will simply fall from whatever height it is at. If you know your flight time, you can estimate at what time you should bring your quadcopter down to a shorter height as to not cause damage.

5. Range of Flight: How far does your quadcopter go? Know your range of flight so you can always be in control. For all quadcopters, there is a 400 foot height restriction to prevent interference with Aircraft.

6. Short list of general rules to know:

– Avoid flying in residential or highly populated areas. Not all people are comfortable with quadcopters, and if you lose control, you could crash into someone.

– Keep your drone within eyesight at all times.

– Check your local laws to see if there are any restrictions on where you can or cannot fly your quadcopter.

How to fly your quadcopter:

Now that you know the lingo and the rules, here’s how to get your quadcopter in the air.

Before you fly, check everything off this list:

  • -Remote battery is charged
  • -Quadcopter battery is charged
  • -Micro SD card is in place if there is a camera option
  • -Make sure all pieces of your quadcopter are secure
  • -Pick a flight location with a soft landing and no crowd
  • -Make sure there is no wind or rain to cause flight problems
  • -Be sure you can maintain a direct line of sight at all times with your quadcopter

Learn the lingo of your Transmitter:If you ever need to refer back to your manual for additional instructions, there will be certain terminology to understand in order to use your controller.                         drone17

Roll: Action of pushing the right stick to the left or right. This will “roll” your quadcopter diagonally to the left or right.

Pitch: Action of pushing the right stick forwards or backwards. This will tilt the quadcopter to move forward or backwards.

Yaw: Action of pushing the left stick to the left or right. This will help you change directions while in flight.

Throttle: Action of pushing the left stick forward. This will adjust the height or altitude of your quadcopter. This is the action you will need to use to get your quadcopter off the ground.

Trim: Buttons that will help you increase or decrease the sensitivity of the roll, pitch, yaw, and throttle.

Getting off the ground: All you need is throttle. Use your left stick to put your drone in the air. Make sure you move your left stick smoothly and slowly to achieve more height. Slowly release your left stick to gently place your quadcopter back on the ground.

Once you feel comfortable with flying up and down, try out the rest of your remote functions. One by one, add throttle and yaw, throttle and roll, and throttle and pitch. Moving between all of these functions will get you more comfortable with flying your quadcopter.                                                                                   Credits: http://www.hobbytron.com/blog/   http://   

How to Fly a Quadcopter – The Ultimate Guide

How-to-Fly-a-Quadcopter-The-Ultimate-Guide-Cover-Image

This guide will show you how to fly a quadcopter, step-by-step.

Everyone goes through different struggles when piloting a quadcopter for the first time. UAV flying definitely has a learning curve.

So if you’re having trouble flying your quad, you’re just getting started, or you’re looking to hone your skills — don’t worry.

You’re in the right place.

No matter your quadcopter model, this guide will help you prepare for your first flight, stay safe, get airborne, and learn some basic and advanced quadcopter flying techniques.

Our goal is to give you a guide that will take out all of the guess work – from going through a pre-flight checklist, learning the controls, controlling your quadcopter’s flight pattern, and even some advanced techniques. Have fun!

Definitions

General terms:

Line of site – The pilot can see their quadcopter during flight.

FPV (First Person View) — The pilot can see where they’re flying through the UAV’s camera.

Parts:

Transmitter/Remote Control – The hand-held device that allows you to maneuver the quadcopter and adjust its settings.

Propellers – They spin according to the manual controls of the pilot. The intensity of the spin correlates to the intensity of the quadcopter’s movement.

Camera – Many quadcopters either come with a camera or allow the pilot to attach a camera to them. This is how pilots practice aerial videography and photography. (A camera came in second place when we interviewed UAV experts about their favorite drone accessory.)

(Note: For simplicity’s sake, this article assumes that the left stick controls yaw and throttle, and the right stick controls roll and pitch. Some transmitters allow the pilot to switch these controls based on what’s most comfortable.)

Roll – Done by pushing the right stick to the left or right. Literally rolls the quadcopter, which maneuvers the quadcopter left or right.

Pitch – Done by pushing the right stick forwards or backwards. Tilts the quadcopter, which maneuvers the quadcopter forwards or backwards.

Yaw – Done by pushing the left stick to the left or to the right. Rotates the quadcopter left or right. Points the front of the copter different directions and helps with changing directions while flying.

Throttle – Engaged by pushing the left stick forwards. Disengaged by pulling the left stick backwards. This adjusts the altitude, or height, of the quadcopter.

Trim – Buttons on the remote control that help you adjust roll, pitch, yaw, and throttle if they are off balance.

The Rudder – You might hear this term thrown around, but it’s the same as the left stick. However, it relates directly to controlling yaw (as opposed to the throttle).

Aileron – Same as the right stick. However, it relates directly to controlling roll (left and right movement).

The Elevator – Same as the right stick. However, it relates directly to controlling pitch (forwards and backwards movement).

Maneuvering:

Bank turn – A consistent circular turn in either the clockwise or counterclockwise direction.

Hovering – Staying in the same position while airborne. Done by controlling the throttle.

Figure 8 – Flying in a “figure 8” pattern.

Flight modes:

(Flight modes can typically be adjusted with certain buttons on your remote control/transmitter.)

Manual – Similar to flying a helicopter. Once you tilt the quadcopter (roll) it will not auto-level itself back to its original position. Even if you let go of the stick and it returns to the middle, the quadcopter will stay tilted.

Attitude (Auto-level) – Once the sticks are centered, the copter will level itself out.

GPS Hold – Returns the quadcopter’s position once the sticks have been centered. The same as attitude mode (auto-level) but using a GPS.

Quadcopter Controls

When learning how to fly a quadcopter, the controls will become your bread and butter.

They will become second nature once you know how they act individually and how they interact together to form a complete flying experience.

With any of these controls, the harder you push the stick, the stronger your quadcopter will move in either direction.

When you first start out, push the sticks very gently so the quadcopter performs slight movements.

As you get more comfortable, you can make sharper movements.

There are four main quadcopter controls:

  • Roll
  • Pitch
  • Yaw
  • Throttle

Roll, Pitch, Yaw, and Throttle of a Quadcopter - Image 1

Simple sketch of roll, pitch, yaw, and throttle on a transmitter (left image) and quadcopter (right image).

(Image source: Quadcopters Are Fun)

Let’s go through each of them.

Roll

Roll moves your quadcopter left or right. It’s done by pushing the right stick on your transmitter to the left or to the right.

It’s called “roll” because it literally rolls the quadcopter.

For example, as you push the right stick to the right, the quadcopter will angle diagonally downwards to the right.

Explaining a Quadcopter's Roll - Image 2

Example of a quadcopter rolling left and right. Notice the tilt of the quadcopter and the angle of the propellers.

(Image source: Best Quadcopter Spot)

Here, the bottom of the propellers will be facing to the left. This pushes air to the left, forcing the quadcopter to fly to the right.

The same thing happens when you push the stick to the left, except now the propellers will be pushing air to the right, forcing the copter to fly to the left.

Pitch

Pitch is done by pushing the right stick on your transmitter forwards or backwards. This will tilt the quadcopter, resulting in forwards or backwards movement.

Explaining a Quadcopter's Pitch - Image 3

Example of a quadcopter pitching forwards and backwards. Note that this view is from the left side.

Yaw

Yaw was a little bit confusing for me in the beginning. Essentially, it rotates the quadcopter clockwise or counterclockwise.

This is done by pushing the left stick to the left or to the right.

Check out the video below for an example.

(Watch from 3:00 to 3:40 and pay attention to how he adjusts the sticks.)

 

Yaw is typically used at the same time as throttle during continuous flight. This allows the pilot to make circles and patterns. It also allows videographers and photographers to follow objects that might be changing directions.

Throttle

Throttle gives the propellers on your quadcopter enough power to get airborne. When flying, you will have the throttle engaged constantly.

 

To engage the throttle, push the left stick forwards. To disengage, pull it backwards.

Make sure not to disengage completely until you’re a couple inches away from the ground. Otherwise, you might damage the quadcopter, and your training will be cut short.

Important note:

When the quadcopter is facing you (instead of facing away from you) the controls are all switched.

This makes intuitive sense…

  • Pushing the right stick to the right moves the quadcopter to the right (roll)
  • Pushing the right stick forward moves the quadcopter forward (pitch)
  • Pushing the right stick backward moves the quadcopter backward (pitch)
  • And so on.

So pay attention to that as you start changing directions. Always be thinking in terms of how the quadcopter will move, rather than how the copter is oriented towards you.

Getting to Know Your Remote Control/Transmitter

A transmitter is a hand-held controller that lets you pilot your quadcopter and control its flight pattern. When you make an adjustment with the sticks, it sends a signal to your copter telling it what to do next.

Check out this picture describing each part of the transmitter:

Right Stick

The right stick controls roll and pitch.

In other words, it moves your quadcopter left/right and backwards/forwards.

Left Stick

The left stick controls yaw and throttle.

In other words, it rotates your quadcopter clockwise or counterclockwise, and it adjusts the height at which you are flying.

Trim Buttons

Each control has its own trim button, as you can see from the image below.

Trim Buttons on a Transmitter - Image

(Image source: Quadcopter 101)

When you first push your throttle to get your quadcopter off the ground, you may notice that the UAV automatically tilts and flies to one direction (or multiple).

This happens when the controls are unbalanced. To balance them out, certain controls need to be trimmed.

Check out the beginning of this video, where the pilot trims a few of his controls:

(Watch from 0:47 to 1:07)

 

If this happens, you can use the corresponding trim button to adjust the control’s natural intensity. This will stabilize the copter when pushing the throttle.

An Overview of the Main Quadcopter Parts

When learning how to fly a quadcopter, it’s important to understand the machine you’re commanding.

If something goes wrong, you want to be able to diagnose and fix the issue. You also want to understand the capabilities of each part and how they play into flying a quadcopter.

Here are the main parts of a quadcopter:

  • The frame
  • Motors
  • Electronic Speed Control (ESC)
  • Flight Control Board
  • Radio Transmitter and Receiver
  • Propellers
  • Battery and Charger

The frame connects all of the other components. For a quadcopter, it’s shaped in either an X or a + shape.

If you’re building your own quadcopter, you want to consider the size and weight of the frame and how it will affect your flying experience.

The motors spin the propellers. A quadcopter needs four motors, because one motor powers a single propeller.

The higher the kV, the faster the motor will spin. Kv is often quoted in RPM per volt, which means that a 1000 Kv motor on a 10V supply will rotate just under 10,000 rpm at no load.

Electric Speed Controls (ESCs) are wired components that connect the motors and the battery. They relay a signal to the motors that tells them how fast to spin.

At any one time, each of your motors could be spinning at different speeds. This is what lets you maneuver and change direction. It’s all conducted by the Electronic Speed Controls, so they’re very important.

The Flight Control Board is the “commander of operations”. It controls the accelerometer and gyroscopes, which control how fast each motor spins.

The radio transmitter is your remote control, and the receiver is the antenna on the copter that talks to the remote control. When you make an adjustment on the transmitter, the receiver is what understands that adjustment and sends it to the rest of the quadcopter system.

A quadcopter has 4 propellers, and each one helps determine which direction the quadcopter flies or whether it hovers in place.

The battery is the power source for the whole quadcopter. This needs to be charged and recharged, because without a battery, you cannot fly your quadcopter.

The charger charges your battery so you can take multiple flights.

(Pro tip: We recommend buying multiple batteries. This way, you won’t have to wait for the first battery to charge in order to take more flights. You can charge the first battery while you insert the second, third, fourth one, etc.)

The Pre-Flight Checklist (Do NOT Skip This)

Going through a pre-flight checklist will keep you and your copter safe.

It will also make sure you don’t waste time fixing components and getting things ready, when you could be having a blast flying your quad.

Here’s a checklist you can use before each flight:

  • If you have a camera, check that you have your micro SD card inserted.
  • Make sure the transmitter battery is charged.
  • Make sure the quadcopter battery is charged.
  • Insert the battery.
  • Make sure the battery is inserted securely.
  • Make sure each propeller is secure.
  • Check that there are no loose parts on the quadcopter.
  • Check for missing or loose screws.
  • Turn on the transmitter.
  • If your copter needs to calibrate and get satellite lock, wait until it finishes.
  • Make sure there is enough room for launch and flight.
  • Make sure the throttle (left stick) is all the way down.
  • Turn on the transmitter.
  • Back away 3 or 4 steps (or to a safe distance).
  • Keep facing the quadcopter the entire time.
  • Keep a direct line of site at all times when flying, so you can always see your quadcopter. You want to keep a direct line of site so you know when you’re about to crash. Also, sometimes, quadcopters can fly out of the range of the transmitter’s signal, which can cause your copter to fly off on its own (bye bye quadcopter). Keep the transmitter’s range in mind, and don’t let your quadcopter fly out of that range.

How to Fly a Quadcopter – Choosing a Place to Learn

Any UAV pilot will tell you that learning to pilot a quadcopter in an enclosed space is asking for something to go wrong – either with you, your belongings, or the drone itself.

As you get more experienced, and your control becomes natural, flying in tight spaces will be a cinch.

But as a beginner, choose a place that will minimize the impact any mistakes might have.

We suggest starting out in a large, open space, such as a park or a field. Many people prefer to learn on grassy ground, so if the quadcopter needs to make a crash landing, it will at least have some sort of cushion.

Next, stay away from people or animals. Any crashes could cause serious injury.

And finally, wind can be your worst enemy when learning the nuances of flying. To reduce the chance of flying in the wind, try to fly in the morning.

Important Safety Precautions

Quadcopters are basically flying lawnmowers.

They can be dangerous if not operated carefully.

Here are some quadcopter safety precautions to keep in mind:

  • If you’re about to crash into something, turn the throttle down to zero, so you don’t potentially destroy your quadcopter, injure somebody, or injure yourself.
  • Keep your fingers away from the propellers when they’re moving.
  • Unplug/take out the battery of the quad before doing any work on it. If it turns on accidentally and the propellers start spinning, you might have a tough time doing future flights with missing fingers.
  • If you’re a beginner learning to fly indoors, tie the quadcopter down or surround it by a cage.

    How to Get Your Quadcopter Off the Ground

    Alright! Now that you understand the controls and you’ve taken all of the right safety precautions, you’re ready to fly.

    To get your quadcopter in the air, the only control you need is the throttle.

    Push the throttle (left stick) up very slowly, just to get the propellers going. Then stop.

    Repeat this multiple times and until you’re comfortable with the throttle’s sensitivity.

    Slowly push the throttle further than before, until the copter lifts off the ground. Then pull the throttle back down to zero and let the quadcopter land.                                                                               (Watch from 1:15 to 1:40)

     

    Repeat this 3-5 times. Notice whether the copter is trying to rotate left or right (yaw), move left or right (roll), or move backwards or forwards (pitch).

    If you notice any movements happening without you making them happen, use the corresponding trim button to balance them out.

    For example, if you notice the copter moving to the left when you push the throttle, adjust the “roll” trim button next to the right stick.

    Keep adjusting the trims until you get a relatively stable hover off the ground by only using the throttle.

    Congrats! You know how to get your quadcopter airborne.

    Now, let’s learn how to hover in mid-air.

    How to Hover in Mid-Air and Land

    To hover, you will use the throttle to get airborne. You will then use small adjustments of the right stick to keep the quadcopter hovering in place.

    You may also need to adjust the left stick (yaw) slightly, to keep it from turning.

    Use the throttle to get the copter about a foot to a foot-and-a-half off the ground.

    Make tiny adjustments with the right stick (and the left, if necessary) to keep the copter hovering in position.

    When you’re ready to land, cut back the throttle slowly.

    When the quadcopter is an inch or two off the ground, go ahead and cut the throttle completely and let the UAV drop to the ground.

    Repeat this until you get comfortable hovering off the ground and landing gently.

    Flying Left/Right and Forwards/Backwards

    To fly a quadcopter left, right, forwards, and backwards, you will need to hold the throttle at a steady rate to keep it airborne. You will then use the right stick to maneuver the quadcopter in the direction you want it to go.

    First, bring your copter to a hover.

    Push the right stick forward to fly it a couple feet forward.

    Pull the right stick back to bring it back to its original position.

    Now, move it further backwards a couple feet, and return it to its original position.

    Push the right stick to the left to move your copter a couple feet to the left.

    Move it back to its original position, then fly it a couple feet to the right.

    If it starts to rotate (yaw), adjust the left stick to the left or right to keep the copter facing the same direction.

    (Pro tip: When you move in either direction, you will probably notice the quadcopter dropping in altitude. To keep the copter at the same altitude, push the throttle and give it more power whenever you turn or move.)

    How to Pilot Your Quadcopter in a Square Pattern

    You’ve gotten off the ground, and you know how to fly a quadcopter in the four basic directions.

    Now, it’s time to combine these skills and start flying in patterns. This will help you get a feel for simultaneously engaging the controls.

    To fly in a square pattern, keep the quadcopter facing away from you the entire time.

    Push the right stick forward (pitch) and fly forward a couple feet. Then, return the right stick to the middle and hover in place.

    Then push the right stick to the right (roll) and fly to the right a couple feet. Then, hover in place for a few seconds.

     

    Pull the right stick backwards and fly backwards a couple feet. Then, hover in place for a few seconds, and push the right stick to the left and return the quadcopter to its original position.

    You’ve just flown in a square! Keep doing this until you get comfortable with it, and then move on to our next pattern – flying in a circle.

    How to Fly a Quadcopter in a Circle

    This is where you will hone your simultaneous control skills.

    To fly a quadcopter in a circle, you will use pitch, roll, and throttle at the same time.

    As usual, use the throttle to get airborne. Then, decide whether you want to fly clockwise or counterclockwise.

    For this example, we’ll assume you’re flying clockwise (to the right).

    Keep the quadcopter facing away from you, and push the right stick diagonally up and to the right. This will engage both pitch and roll at the same time, and start flyinging the quadcopter in a circle to the right.

    After a couple feet, start rotating the right stick more to the right, so you engage more roll. This will start maneuvering your quadcopter to the right.

    After a few more feet, start rotating the right stick diagonally to the bottom right, and continue to circle the right stick around until the copter returns to its original position.

    Try changing directions, and slowly rotating the right stick to fly in a circle. If you notice the quadcopter starting to rotate and face different directions, adjust the quadcopter’s yaw by pushing the left stick to the left or right.

    How to Rotate (Yaw) Your Quadcopter

    To rotate your quadcopter, use the throttle to get airborne.

    Once at a comfortable hover, push the left stick in either direction. This will rotate the quadcopter in place.

    Rotate it 360 degrees. Then push the left stick in the opposite direction and rotate it 360 degrees the other way.

    Keep doing this until you’re comfortable with it.

    Flying a Quadcopter Continuously

    Flying a quadcopter continuously requires you to rotate and change directions simultaneously.

    This will take some getting used to, because the quadcopter will be facing different angles in relation to how you’re facing, so you will need to pay close attention to how each movement of the sticks will affect the quadcopter’s flight.

    First, take off and hover.

    Rotate (yaw) your copter to a slight angle.

    Use the right stick to fly it left/right and forwards/backwards. Get comfortable flying the quadcopter while it faces a different direction.

    Rotate it to another angle, and use the right stick to maneuver it again.

    Keep doing this until you’re comfortable flying at different angles.

    To fly continuously, slowly push the right stick forward.

    As you’re pushing the right stick forward, push the right stick slightly to the left or to the right at the same time.

    Fly in different directions by pushing the right stick forward (pitch) and adjusting it left and right, and using the left stick (yaw) to change the direction the copter is facing.

 

Then, try adjusting the quadcopter’s height by moving the left stick forward and backward (throttle).

Congrats! Now you know how to fly a quadcopter with continuous movement.

Keep practicing until you can direct your quadcopter at will. Then, move on to the next section, where we’ll discuss different milestones for you to shoot for.

RC Helicopters

 

Beginner’s Guide to RC Helicopters

NOT LONG AGO, RC helicopters were nothing more than a curiosity. There were only a handful of kits on the market and you practically had to be a mechanical engineer to put one together.

There might be one—or if you were lucky, two—helicopter pilots at a local flying field. Helicopter pilots would usually be left to themselves, subject to an array of whispered jokes such as, “Those things don’t fly; they are so ugly the ground repels them,” or “They don’t fly, they beat the air in to submission,” and others. Knowing looks were exchanged by the airplane pilots that said, “He’s a nice enough guy but he’s a little strange; he flies helicopters.”

Fast forward to today. At many flying fields, the helicopters present at a field can equal or even exceed the number of airplanes. Even if they are hidden in the back seat of their trucks, many of the sneering airplane pilots secretly own an electric helicopter or two.

Now there are so many kits available in nearly every imaginable shape and size that a beginner interested in getting started in the hobby can easily be overwhelmed. Offerings range from RTF helis that you can unpack, charge, and fly, to kits that you have to build from bags of parts.

Sizes range from diminutive electric-powered models that you can fly in your living room to turbine-powered scale masterpieces that require a trailer to transport them to the flying field. A first-time helicopter buyer is likely to encounter a confusing array of terms such as ARF, RTF, BNF, coaxial, fixed pitch, collective pitch, electric, nitro, and gas.

What this article is going to attempt to do is explain these terms and help the first-time helicopter buyer make an informed decision concerning which category best suits his or her needs and interests.
Size (abridged from article):Modern electric-powered helicopters are slightly more difficult to classify size wise, but they generally range from rotor spans in the 7-inch range (the tiny T-Rex 100) to the 700 size, spanning nearly 5½ feet. I’ve seen an electric-powered Scale helicopter with a main rotor span of slightly more than 90 inches!

Loose comparisons can be made to nitro-powered helicopters. A 550 electric is roughly the same size as a .30-size fuel-powered helicopter; a 600 electric is .50 size, and a 700 electric is .90 size. The 100 through 450-size smaller electrics have no mainstream fuel-powered equivalent.

Many factors go into deciding which size helicopter to purchase.
Flight Controls (abridged from article): Not unlike an airplane, a helicopter requires four primary flight controls: pitch (elevator), roll (aileron), yaw (rudder or tail rotor), and throttle. The elevator and ailerons are combined on the right stick (Mode 2) in what is called the cyclic control. This is what gives us directional control of the helicopter.
Rotor Head Designs (abridged from article): As mentioned, we generally have two types of main rotor head design: fixed pitch and collective pitch. The advantage of fixed pitch is that the design is simple so it’s inexpensive to produce.

As the name implies, the pitch angle of the main rotor blades is fixed and the amount of lift produced varies by changing rotor head’s rpm. In addition to the simplicity of the design, a fixed-pitch rotor head requires only one channel to control altitude.

The disadvantages of fixed pitch are that performance is somewhat limited, and if you get the rotor head too slow while descending, you might not get the rpm back in time to prevent impact with Mother Earth.
Tail control (abridged from article): Torque produced by the main rotor has to be counteracted or the heli’s fuselage will spin in the opposite direction of the main rotor. Typically this is accomplished by the addition of a tail rotor.

Like the main rotor system, the tail rotor can be either a fixed-pitch variable-speed design, or a fixed-speed variable-pitch design. Fixed-pitch tail rotor designs have a small motor mounted on the tail and the variable pitch ones drive the tail rotor from the main motor.
Fuel or electric power (abridged from article): The debate between fuel power and electric power has been going like the Energizer Bunny. The winner is … there’s no clear winner. Each has its own learning curves and unique support equipment to purchase.

In the case of fuel power, you need a fuel pump, glow plugs and a way to light them, and, of course, fuel. Then you have to learn to operate and tune an internal-combustion engine. Most fuel-powered helicopters use traditional model fuel (methanol, oil, and nitro methane), but there are two-stroke gasoline-powered engines available as well.

Several flights can be made on a single receiver battery charge so you can get a number of flights in while only stopping to refuel.

If you go with electric power, there are speed controllers, motors, and batteries to purchase. To fully explain how to properly choose your electrical system components such as the speed controller, electric motor, and batteries would encompass a small book.

Fortunately there are a number of packages available, supplied with components chosen from extensive flight testing, that are proven to work well together. Then you have to learn how to properly charge, and handle LiPo batteries.  Credits: http://modelaviation.com  Written by Andrew Griffith   http://       

 

Know the Different Battery Types for Electric RC Vehicles

Various RC vehicles run on different power sources. Among these, RC cars or boats that run on electricity are the easiest to operate. With electric remote control cars or boats, there is no need for sophisticated technical knowledge or the need for glow plugs or fuel.

The only requirements are to charge the batteries and to ensure correct wiring. That’s pretty much it!

Rechargeable battery packs for RC vehicles can be typically either one of the following: NiCd, NiMH, or Li-Po cells. Following are more information on RC batteries.
