RC helicopter blade tracking has been a mystery to many new RC helicopter owners, but I'm going to demystify the whole concept for you right now so that you'll have a complete understanding of blade tracking by the time you finish reading this article.
First, we need to answer this important question: What is blade tracking?
Essentially, blade tracking is when one rotor blade rotates in a circular motion and the following blade follows exactly behind it. Both rotor blades spin on the same plane without one blade being higher or lower than the blade it's following. Another way to look at it is that both blades travel through the same airspace created by their spinning. If the rear blade is following the front blade on a higher or lower plane, then it can cause a lot of unwanted vibrations for the RC helicopter.
How To Track Your Blades
If you're flying your RC helicopter for the first time, you need to see if the blades are tracking properly and you may need some help from an experienced RC helicopter pilot. You can check the blade tracking by simply hovering the helicopter in place at eye level and looking at the blades as it hovers. If you see a lot of shaking and vibrating, your RC helicopter is more than likely not tracking properly. If you're not sure if it's tracking properly, do this:
Get two different colors of tape and apply a small strip of one color to one blade. Put a red strip on one blade and a blue strip on the other blade. By using a different color on each blade, it makes it a lot easier to see which blade might be out of track.
Now that you've applied the colored tape, have an experienced RC helicopter pilot hover the helicopter in place so that you can see the blades as they spin. As you watch the blades spin, you'll know if they're in track if you only see a single circle or both blades spinning on one line. If you see two circles or two lines, (red above blue or vice versa) then you'll know that one of the blades are off and needs to be aligned.
To properly track your rotor blades, you need to land the hovering RC helicopter first. After the blades have stopped spinning, you can adjust the blade that is out of alignment. You'll need to have your RC helicopter manual handy so that you can look up the proper blade tracking information in it. Be sure that you adjust the correct linkages in what the manual says and not what someone says. This is the best way to be sure that you've done it correctly.
Once you've tightened or loosened the correct linkage or linkages, you need to have someone fly the helicopter again so that you can look at the blades. You'll repeat this process as often as needed until your blades are tracked properly and they spin on the same plane. Once you've completed proper blade tracking, your RC helicopter will handle a lot smoother than it did before and be much easier to fly.
In this RC helicopter review, we're going to look at the main features of RC helicopters, and just how far the market has come along over the last decade. Since the launch of RC helicopters on to the mainstreams, the ongoing drive for innovation and new product developments has meant that these helicopter models have come on leaps and bounds over the period, and as a result now represent a much more fulfilling flying experience. Whether you're a novice with no interest beyond the pure and simple fun of having a go, or you're much more serious about your hobby, taking on board these vital elements of the RC helicopter review will allow you to decide how best to go forward with your helicopter purchase.
What should you look for when buying your helicopter? What are the best options available on the market? What do you need to do to refine your search to only the best value for money products? Let's get stuck in to answering these questions.
What Should You Bear In Mind?
RC helicopters were not all created equal, and in this RC helicopter review, we're happy to lay it out like it really is. Unfortunately, too many product reviews online are clouded with bias and are anything but independent. That's why it can often be difficult to know what you need to lock for, and what factors make a helicopter a worthwhile purchase. The things you need to bear in mind are the difference between various different models. Are you looking for indoor or outdoor flying? Are you looking for a quiet, electric-powered helicopter, or would you prefer a more robust but noisy motorized product? You need to bear in mind that different helicopters fly differently and provide different functions and features that may make them more or less suitable for your needs.
Channels?
Then there's the question of channels. Channels are essentially what dictates the range of dimensions in which your helicopter can move. Two-channel models are much more limited, and as a result tend to be favored by kids or new helicopter fans. For more advanced fliers, this RC helicopter review recommends 4 or 6 channel helicopters. These may be in practice more difficult to fly, and more difficult to develop control familiarity, but for the helicopter fan who wants the full scope of movement and the most realistic flying experience open to him, the more channels available the better. Remember also that you'll pay more for more advanced technology, so expect to push your budget if you're looking to buy anything more serious.
Budget
The dreaded B-word. When it comes to buying, none of us like it, but we need to think about budget and ensuring we're getting great value for money. A crucial step in that process is buying only what you need - both in terms of functionality and quality. Buying something that is a souped-up rocket isn't going to do your wallet any favors, so don't expect to be loading up on cheap rate, quality products. You most definitely get what you pay for, so make sure you know what you want and intend to buy before settling on the most persuasive RC helicopter review for you.
In a nutshell, this RC helicopter review highlights the difficulties of choosing a helicopter if you don't know the market. Provided you shop with at least some care and attention, you should be able to get yourself to the stage where you're ready to buy the most suitable product for your needs, at a price range that won't break the bank.

The main goal of hovering an RC helicopter is to keep it in one spot with as little moving or drifting as possible. Ultimately, you'd like it to remain absolutely motionless, but in a non perfect world, that's nearly impossible as there are too many factors that will cause drift or motion. For the beginner pilot hovering an RC helicopter can prove to be excessively difficult and many people give up on the hobby because they can't master hovering. While it is possible and people do fly RC helicopters without being able to hover properly, it's not recommended. It's like learning to run before you can walk and you'll eventually run into a problem. Being able to hover teaches control and fine motor skills that you'll want to have to become a better overall pilot. Even top performers practice hovering to hone their skills. There are 4 main hovering positions, or 8 if you count inverted hovering, but I'm not going to get into that as it's a lot more complicated than learning basic, right side up hovering that we'll discuss in this 'how to' article....
Tail in hovering is where the tail is pointing towards you and the nose of your helicopter is away from you. Nose in is the opposite - where the nose of your helicopter is pointing towards you and the tail is pointing away from you. Right side in is where the nose is pointing to the right, the tail is pointing to the left and you're facing the right side of the helicopter. Left side is the opposite, where the nose is pointing to the left, the tail to the right and you're facing the left side of the helicopter.
Pre-flight Setup & Checklist
Before you can learn to hover your RC helicopter, you need to make sure your helicopter and radio is properly setup. If unsure, consult an experienced pilot or your local hobby store. Put your training gear on. If you don't have some, buy it. It costs - and if you're just starting out will save you hundreds in crash damages. The training gear also makes a good visual aid that help you see the pitching and rolling of your RC helicopter before you notice them in your helicopter. If you're flying a nitro helicopter, have lots of fuel available. If you're going electric, make sure your batteries are charged and have more than one available if possible. The more you can fly continually, the faster you'll improve your skills.
Make sure your gyro is set to heading hold mode. While some people recommend flying with a gyro in rate mode because you'll get a better feel for the helicopter, I don't recommend it for the simple reason that unless you plan on building scale ships, you'll probably never use rate mode, so there's no sense learning to fly with it. Also, make sure your radio and helicopter is set up for hovering and that it's not too sensitive. If it's too sensitive or quick to respond, you can try adding some expo to the cyclic to soften the sticks around their centres, or decrease the endpoints to decrease the amount of cyclic pitch and responsiveness of the helicopter. And finally, go through your preflght checks.
Getting a Feel for Your Helicopter
Before you learn to hover, you need to understand how your RC helicopter works. When you move the sticks, how does your helicopter react? If you input right cyclic, how quickly does your helicopter react? The goal is to learn how your helicopter moves and corresponds with the inputs you give. Once your RC helicopter and radio are setup, you'll need a practice area. You're going to want the surface you're practicing on to be as smooth as possible so you can slide around a bit. A gym floor, a large and smooth cement basement, a ice rink or a smooth asphalt make the best practice surfaces - the smoother the better. If you're trying to learn on a rough or uneven surface like grass or gravel, your RC helicopter can catch on it and tip over. The training gear will help you slide around without fear or tippage. Make sure you have at least a 10ft x 10ft (20ft x 20ft or larger recommended) area that is clear of any and all obstructions. The larger your helicopter is, the more space you'll need. If there's no marking to use as a reference point, use a marker or masking tape to create one. Put your helicopter into the middle of the space pointing into the wind (if outdoors) and stand 10 - 15ft behind it. Start to throttle up very slowly - you don't want it to lift off the ground, just get it light on the training gear so you can slide it around. If your main blades rotate clockwise and your helicopter has been built properly, there's a good chance that it will want to drift slightly to the left to counteract the tail rotor thrust pushing to the right. If your rotors spin counter clockwise, your helicopter should drift slightly to the right. Use the trims to compensate for the drifting until your RC helicopter stays fairly stationery. Once you've got the trims set, give a little right cyclic input and watch as the helicopter moves to the right. Then give left cyclic input to move it back to the reference point. Then do the same thing moving your helicopter forwards and backwards. The main goal here is to get a feel for how the helicopter responds to your stick inputs and how much input is necessary to get it to move. You'll find small stick inputs are all that is necessary. Once you're comfortable with side to side and forwards / backwards movement, bring the helicopter back to your reference point and move it diagonally in all 4 directions. This will be a lot harder then left/right forwards/backwards movement because you'll be inputting multiple cyclic commands simultaneously as well as controlling the tail. You'll want to practice this until you can make very precise movements and are comfortable moving your helicopter around. Remember to always fly your helicopter by watching its nose, never by looking at the tail boom.
Learning To Hover All right...on to the good stuff.
Once you've got a feel for how your helicopter moves and how to control it using your radio, it's time to get it off the ground. For this, you'll want to move from your smooth surface to something softer, preferable short grass. This will help to absorb any impact from hard landings and prevent damage. If you have a really small or micro RC helicopter, you can do this on the same hard surface you used earlier as there's not much weight to cause damage. Pick or mark a reference spot and place your helicopter there going through all the pre-flight checks mentioned earlier. Input collective until your helicopter is just a few inches off the ground and try to hold it there. Remember that very small inputs make a big difference, so be gentle on the controls. Pay attention to your helicopter and the balls on the training gear and try to anticipate any movement and try to compensate for it in advance. To become a masterful hoverer you need to be able to tell what's going to happen in terms of movement and react to it in advance to prevent it from happening. As you become more comfortable, start to bring it a little higher and higher until you get it up to 2 - 3ft and can hold it in one spot.
Congratulations!!!
You can now hover an RC helicopter... everything else is downhill from here. Though you'll probably want to go through at least 3 - 5 batteries or tanks of fuel practicing stationary hovering before you start to move your helicopter around to make sure you'll be able to react in time in case of a mishap. As s side note, when practicing hovering, you'll usually want to hover above 2 - 3ft to avoid ground effect. Ground effect is when your RC helicopter is hovered close to the ground (under one rotor diameter) and the downwash of the rotor blades creates a high pressure bubble of air. This bubble of air applies an uneven upwards force which causes the helicopter to wobble or move sideways making stable flight difficult. It's a little like balancing a basketball on your finger (when it's not spinning). For those reasons, when practicing hovering, I prefer to hover at about 3 - 5ft. It's high enough to avoid the ground effect and low enough that I'm looking slightly down at the helicopter and can use the ground as a reference. The higher you get, the harder it is to perceive depth and keep the helicopter in one place - there's also no easily perceivable frame of reference against the sky as there is on the ground. However, with that being said, if you're just starting out you might want to hover a little higher in case you make a mistake so you have time to recover. Many people use the saying "practice 2 mistakes high" meaning that you have time to recover from at least two mistakes before your helicopter becomes acquainted with the ground, the hard way. Tip: Use a simulator for practicing and once you're comfortable on your computer try it on your RC helicopter. Once you're able to easily hover your RC helicopter tail in, it's time to start moving it around a little. Repeat the same left/right forwards/backwards and diagonal movements that you did in the previous section, but this time your helicopter will be 2-3ft in the air and when you get to your new position, hold it there for 15-20 seconds before moving on. Transitioning from flight to hovering will help to improve your skills and take you to the next step. Stationary side in and nose in hovering is significantly more difficult than the tail in hovering exercises mentioned in this article because cyclic commands are 90 or 180 degrees off depending on the position. For example, when nose in hovering, if you input a right cyclic command, your helicopter will move to the left and vice versa, so I'll save them for another time.
Now go out there and enjoy your Remote Control Helicopter, by far the best remote control toy money can buy.
What is the best remote control helicopter?
I've been very interested lately in a lot of different models of RC helicopter and as I've been doing my research trying to decide which one to buy next, I've come to realize just how many different types of RC choppers there are!
The first thing you need to decide is whether or not you want to buy an indoor chopper or an outdoor chopper. Now, an indoor chopper is strictly indoors and these can usually be had for around -40 dollars. Outdoor choppers will run you more money but they are usually larger and have better performance over all.
Keep in mind that with some outdoor choppers you won't be able to fly them inside at all. They are simply too big and require too much room to maneuver to make flying them in a typical room unpractical. There are however some models that sort of blur the line between indoor and outdoor like the Madhawk 300 which is big enough to perform outside (as long as it's not TOO windy) but small enough that you can practice indoors. Once you decide on an indoor or outdoor model than you consider these types before making a purchase:
Double Co-Axial Choppers
These are your basic indoor "toy" helicopters. They are easy to fly, easy to maintain and will generally provide a great deal of fun while cruising around your apartment. They aren't suited for outdoors as the slightest breeze will take them high into the air or smash them into the ground (usually causing a lot of damage!). They make a great conversation piece for your office and are perfect for wasting a bit of time!
Single Co-Axial Choppers
Basically the same as the above except some of these are large enough to fly outdoors. They are stable enough that pretty much anyone can get them to hover and move forward without much effort. Again these are beginner choppers.
Micro RC Choppers
These are the ones that you're probably most used to seeing these days. Normally they will fit in the palm of your hand and although the basic gear underneath is usually the same, they come in a variety of styles including Military and Commercial air craft. When they first appeared on the scene these choppers were really nothing more than cool looking toys that did not fly very well but with recent advancements in the technology these choppers are VERY flyable and are perfect for beginner-intermediate users looking for an easy to fly chopper to hone their skills on.
4 and 6 Channel Choppers
These are the more advanced choppers for people who are into modding and upgrading. Probably not a good first-time chopper as they are more expensive and more prone to damage in the event of a crash (and trust me, you will crash them!).
2.4 GHz Remote Systems
These days you should always try and go with a 2.4 GHz remote system. This refers to the frequency that the choppers controls operate on and 2.4 takes up less current than the older systems. Meaning you get more flying time for each charge and in the world of RC Helicopters, flying time is what it's all about!
The Best Chopper?
Well as you can see, it really depends on your level of skill and where you want to use it. But, from personal experience I would recommend: The Syma S107 for an Indoor Chopper and the Madhawk 300 for an indoor/outdoor chopper. Both are priced very reasonably and offer great quality for the money. Please check out my link below for more detailed reviews on both of those choppers as well as other great reviews on all sorts of RC helicopters and replacement parts!
Cheers!

If you are looking for high advanced technology in your toy helicopter, then a good option would be the new and popular RC helicopter camera. RC helicopter has evolved into a big brand in the last couple of years due to its high quality helicopters and advanced technology.
Now let us check out some of the benefits and features of this camera on RC helicopters. Firstly these cameras are so small in size that you can hide the camera anywhere in your helicopter. Not only this, you could put it in other RC models also, like the RC airplanes and motors. It is quite adjustable and can be fit into any RC product.
With this, you get the facility of video camcorder with which videos can be shot. You can use it as a spy camera. It can be used to capture video. The best part of the camera is that you can capture a long video of nearly one and a half hour.
It has got a space of 2 GB which you will get free. Not only this you may even add up to 4GB to this camera for extra space. So if you want to capture a long video you really do not have to think so much about the time and space of the camera. Now with the inbuilt space of 2GB you will be able to capture a video as long as one and a half hour or more.
Now let us get into the features of these cameras. These cameras that are used in the RC helicopters have got such specifications that the final picture clarity, which you will get, is very high. It has got 648x480pixels camera resolution. Thus the video captured with it will be of very good quality. The weight of this camera is 18 gram.
With this camera you will also get some of the additional accessories like the USB cable and a manual guide for the user and a free 2GB card. So if you are a beginner also you will not find it tough to handle this at all.
Some of the other specifications of this camera include avi video format, mini camera that is mall and can be used anywhere. The size of the camera is nearly about 73mm*20mm*11mm. Apart from this you will get clear video image, clear sound effect in the captured video, wireless camera. So there is no use of long wires or cords.
Now the question comes, from where you can get these camera helicopters? Well you could get these helicopters from all the major hobby shops. But before you actually purchase it, check the camera resolution properly.
The price of this helicopter starts from a minimum .95 and goes to .95. So according to your budget you can buy the helicopters. But when it comes to child's happiness, parents really do not think much about the price.
So if you want to surprise your child with a very new and innovative helicopter then get him this RC helicopter camera.
The UJ376 RC Helicopter is an easy to fly 3 channel helicopter. This helicopter is designed for indoor and outdoor flight. The double rotor design helps stabilize flight and makes it easier to control.

Recently I got the question, "Where do I get parts if I crash my helicopter?"
It's a good question, but I don't recommend you buy a radio control helicopter believing you're going to crash it the first time you fly. And I don't think it wise to start your first flight by seeing how much scattering effect RC helos have on clouds either.
Learning how to control a helicopter is a learning curve that stands uniquely apart from any other radio control vehicle. A radio control airplane comes in for its landing in a glide-type path, moving horizontally, and you usually set it down on landing gear so it rolls to a stop once you contact the ground. (Or you brake it to a stop on planes that have braking systems.)
But you don't land a helo that way. Sure, sometimes you're slipping sideways as you approach the earth, but helicopters have no wheels to absorb some of the impact. When you land that remote control helicopter, you land it... or crash it.
For you first-flight RC helicopter pilots, I suggest a focus on basic helo flying lessons. Get a list of the basic techniques, slowly learn them in their proper order, and practice each technique until you find a comfortable skill level with that technique. Then start working on the next technique.
You can get an RC flight simulator, and learn to fly your model with a computer too.
Of course, your best option is take lessons from a skilled and experienced radio control helicopter pilot. If you know experienced RC helo flyers, ask them for some pointers. Most hobbyists eagerly help novices get started.
If you don't know anybody try searching online for local radio control hobby clubs. Every year here in Indianapolis, either in March or April, the annual radio control submarine regatta is a feature on the television news. RC flying doesn't get that much attention, but plenty of radio control model clubs are around. I don't believe Indianapolis is unique in that respect.
If you can't find anyone for one-on-one training, do a self-study. It'll take longer, researching the information and studying it. But the opportunity to learn is there.
Once you set up your RC helo, practice flying at low altitudes. I'd say not higher than 5- or 6-inches off the ground. Don't go any higher than that.
Get comfortable with hovering. When you're skilled enough to hold the helicopter in position for minutes at a time, start practicing slow side slipping. Get a feel for controlling your helicopter, and build your confidence.
Then practice landings. Pulse your helo to prevent a crash. Increase altitude, and then decrease altitude. Alternate the increase, then decrease action, each time coming a little closer to the ground on the decrease cycle.
If you do crash from 5- or 6-inches high, you won't do a lot of damage to your aircraft. And you easily replace broken rotor blades on most helos. The manufacturers often include spare rotors with the helo in case you break one, or they make replacement blades available online.
The main thing is learning your flying techniques slowly. You'll begin "feeling" your controls and master the art of RC helicopter flying quick enough if you ease into the learning curve.
The payoff for all that hard work is total thrill as you graduate to flying more complicated radio control helicopters.
Oh yeah, and pleasure when you see the amazed looks on the faces of the people around you.

Other than fuel types, what are the major differences between electric and gas-powered remote control helicopters?
Gas-fueled remote-control helicopters are more complicated to use and are generally larger in size than electric models. Electric-powered RC helicopters run quieter because they are powered by either a brushless motor or a brush motor. Although gas-fueled models are noisier, these RC helos have more powerful engines; many pilots find them more exciting. Gas RC helos can fly faster and longer, but these high-fliers require more flying space and maintenance.
Which type of remote controlled helicopter is more expensive, gas or electric?
Gas-fueled remote control helicopters are more expensive because they are just like real helicopters. They have an engine powered by gas or nitro. Gas models run larger and require more power to operate.
Which, gas or electric helo, is more economical in the long-term?
Electric-powered models cost less in fuel -- no need to purchase gas or nitro -- and the parts are generally more affordable.
What type of RC helo requires more maintenance?
Gas-fueled models take more tinkering and can be messy because they have to be filled with gas or nitro before a flying session. They also have to be cleaned up after the flying session. The gas-fueled models are also more difficult to repair.
Which electric-powered remote-controlled helicopter models are top-quality?
I would recommend the Align T-REX 450, Align T-REX CF 600, Guai Hurricane 425, and Guai Hurricane 550 models.
Which gas-fueled RC helo models are top-quality?
The Align T-REX 600 Nitro Pro and the Align T-REX 700 Nitro Pro models are both great choices.
Which electric-powered RC helos are ideal for a beginner?
The Esky Honey Bee 2, Esky Honey Bee CP3, and the Art-Tech Falcon 3D V3 models.
Which gas-fueled remote control helos would you recommend to beginners?
Beginners should start with an electric model; gas-fueled models, as mentioned previously, are more suited for pilots who have owned remote control helicopters previously, as well as pilots who have had flying licenses.
Who is more likely to have fun with an electric-powered model?
The following types of fliers would be best suited for electric remote-controlled helicopters:
Those with more limited budgets Those who'd like to easily buy spare parts Those who don't want to deal with maintenance Those who have no experience and/or Those who don't have much space for flying.
There are hundreds of remote control helicopters available in the market these days. It is important to choose a right helicopter for a right skill level. I am focusing here only for the beginner or novice flyers. There are few things you have to consider when you buy your helicopter at the beginner's level. It is highly recommended that you buy an electric power helicopter because an electric helicopter does not make as loud noise as nitro powered engine and also, it can be flown indoor. The second thing you need to look for is the size of the helicopter. If the size of the fuselage over 12 inch, it makes harder for a novice flyer to fly indoor as it requires more power to lift off making it harder to control. If you have never flown RC helicopter or still leaning, it is to your advantage to start with a small (Mini) electric helicopter as the smaller electric helicopters can be flown indoor in your living room.
You can begin with an inexpensive mini helicopter that cost less than . They come with an infrared control unit and some spare tail rotors. This type of helicopter has only 2 controls. They are up and down and right and left yow. In order to go forward, you may have to add little weight on the front. However, this is good enough to practice to lift off and landing smoothly for the beginners.
The next step up is Megatech House-Fly Unlimited 2.4GHz 8" helicopter. This helicopter has the Megatech dual rotor/fly bar technology which enables the novice pilot to have successful flights even while learning. The rotors are driven by 2 individual motors for each router and 2 servos to control pitch and roll. The turning right and left (yow) is controlled by differential motor speed. The tail rotor is not required in this model. With this kind of helicopter you can hover, go up and down, forward/backward, and slide right and left as well as turn right and left. I highly recommend to buy one like this with comparable functionality. It is very important to that the rotors are driven by 2 separate motors and pith and rolls are controlled by 2 servos. Once you mastered in this kind of helicopter, you can move up to level 2 flyer.
