Radio Controlled Hobbies: A Technological History

You push a lever on your remote, and your remote control plane veers to the left. It almost seems like magic. Radio control is one of the most magical inventions of the modern era. It has a very long and intriguing history.

Linguistic research into the origins of the word radio reveals that it was from the prefix radio-meaning concerned with radiations. The word radio came into being before Hertzs discovering of electromagnetic radiations. Initially what was radio-telegraphy and radio-telephony over time came to be just radio. One of the first people to popularize the term was another pioneer in America in the field of wireless transmission: Dee Forest.

Tesla demonstrated wireless telegraphy in 1893 almost eight years after the discovery of the electromagnetic waves by Hertz. Jagdish Chandra Bose in 1894 used electromagnetic waves to ignite gun powder and strike a gong in Calcutta (Now Kolkatta) in India. That possibly was the dawn of wireless/radio communications and its applications in science. Tesla in 1896 transmitted wireless signals for nearly 30 miles distance and patented his first four tuned circuit wireless system as being the first practical wireless transmission equipment. Marconi in 1899 spanned the English channel with this wireless transmission.

The dawn of the new century also was the beginning of a new era when Marconi performed the first trans-Atlantic radio signal in 12th December, 1901. The crystal sets which were patented by J.C. Bose came to be commonly used for detecting and receiving radio signals. There have been numerous disputes over who exactly was the first to conceive the idea or wireless transmission, Tesla or Marconi. In between somewhere there is one Popov who was also a pioneer in this field! Tesla is said to have run into financial troubles that greatly limited his run in the race. But nevertheless, Tesla seems to have been the first, but the controversy over this is not our concern now. Whoever it was, the truth stands is that it was one of the finest inventions in the history of science.

The first decade of the century saw many entrepreneurs and experimenters working with wireless radio but it was about at the near end of the first decade that definite hobby interests sparked. Radio signals were originally produced by spark transmitters, which were noisy and inefficient. Then the alternator-transmitter and then the arc-transmitter came into being.

The invention of vacuum-tude diodes and triodes revolutionized the radio transmission and receivers. The invention of triode amplifier generators made audio possible and started a new era of audio radio. The vacuum tubes were the staple component for a long time until the invention of the transistor which made the equipment more precise, concise and efficiently mobile!

Then, AT&T used the vacuum tubes to transmit voices over phone lines and this lead to the experimenting of speeches over long distances for audience to hear over loudspeakers. Commercialization was thought about from the initial days but there was no way to restrict the transmission to specific paid users and broadcasting remained commercial-free. Then AT&T started the idea of advertising to finance the programming, and it is here to stay until this very date. There have been constant innovations in the field of radio broadcasting with the latest craze being internet radio. So, radio is NEVER out of date but it is forever coming in new forms.

The Basics Of Radio Controlled Plane Flight

Radio controlled planes can rack up quite a bill when you consider all of the different things you have to buy in order to enjoy the hobby. You have to buy the plane model itself, as well as all the radio and motor equipment to keep it in the air. Then you have to buy gasoline, or pay for electricity to charge the battery. All in all it can be a very expensive venture. After you spend all of this money, nothing is worse than seeing your investment crash to the ground and erupt into a huge fireball (well, maybe not the fireball part; however, you can expect all of your components to be smashed beyond any working state). So when you fly your plane for the first time, you have to use extreme caution in making sure that you dont ruin your plane and consequently waste your money.

The most important part is to choose the day and the place carefully. On the ideal day, there are perfectly clear skies, with little to no wind. Hopefully it is also warm, but if it isnt that wont jeopardize your mission (unless you are shivering so much that you cant effectively control the plane). You should go to a place that offers some sort of good take-off point. Sidewalks and roads are perfect for this. You should also try to look for an area that is low on houses, trees, and preferably doesnt have many people around.

First you need to check all of your equipment. Even if you are a pro at handling radio controlled planes, nothing can save you from faulty equipment. Check and double-check everything before you send the plane up. Be sure to pay special attention to the landing gear. Make sure it is secure, and that it will be able to withstand the force of impact when the plane touches the ground after you are done flying. Also check all of the connections between the motor and the fuel supply or batteries. Test all of the radio equipment to make sure that every motion is interpreted by the plane. Hold it in your hand as you or a friend tries all of the levers and knobs.

Set your plane on some sort of surface that will act as a good runway. If youre in a park with sidewalks, find a large strip of sidewalk that will give your plane plenty of room to roll, gather speed, and take off. Just make sure there are no people walking in the way. Get up to speed, and if everything goes right you should lift smoothly in the air. Hopefully you will have read through the manual that came with your plane. Every radio controller is slightly different, so I cant give you detailed instructions on that aspect of the flight. You will have to read your manual to find out how to do it well.

After the flight you need to do yet another inspection of the equipment. If it was in good shape at the beginning of the flight and the flight went by without a hitch, it isnt likely to have some sort of new problem that has suddenly shown up. However, you should always investigate anyways, and save yourself some grief in the future. If you notice something wrong, you can take the plane directly home and take care of it, rather than wait until you notice it the next time you come out to fly.

Follow all of these procedures, along with any local laws or regulations that may affect your flying session. Flying is a fun hobby, and if you are able to follow all of the guidelines that I have provided, as well as any other factors that may affect you personally, then you will find it to be a very enjoyable and worthy pastime.

Choosing A Radio Controlled Plane

When you buy a radio controlled plane for the first time, you may have some difficulty choosing the plane that will introduce you to the remote controlled hobby. You will want something that will be fairly cheap to purchase, and will give you a chance to learn how to fly remote controlled planes before you move onto more advanced planes. If you buy the first plane that you see, you could end up having a very bad experience for your first time, and be completely turned away from the hobby. This is why it is very important to know that there are many different characteristics that you can look for. In this article I will go over most of them. So read on to find out about what you need to look for to have the best experience possible when you fly a radio controlled plane for the first time.

First you need to assess your own building skills. You can buy airplane kits that require you to build the entire thing from scraps of wood, or you can buy kits that just require you to snap a few parts together. If you want to make a huge, prolonged project out of your radio controlled plane, then you can buy one that requires full assembly. However, you should always be sure that your building skills are up for it. If you dont want to spend the time required to do this, or if you dont have the prowess to build it, then you can buy a plane that does not require any assembly at all. You just pull it out of the box, and youre ready to go flying for the afternoon.

Next you will want to look for something that has stability for people without are flying for the first time. It may not seem like it, but to fly a radio controlled plane you need at least some skill. But, if you search for the right item you can find something that is more geared towards beginners. Slow flying speed is always a benefit, just as driving slow is a good way to learn how to control a car for the first time. You will want a light plane with larger wings that can catch the wind better. This will make takeoff easier. You will also want to look for planes that have flat bottoms, and wings mounted high on the body. If you get a plane that has all of these features, your maiden flight will be as smooth as possible.

Next you need to consider the model of the airplane you are going to buy. You can get model replicas of almost any type of plane, from the first Wright Brothers plane to modern military jets. If you are buying a model plane, you are probably already interested in planes to begin with. Think of what plane you are most intrigued by when you look through plane books, and see if you can find a kit that is modeled after that plane. This will give you a personal interest in the model that you are getting. When you fly it for the first time, it will be almost like being in the cockpit of the actual plane.

After you have decided on these issues when picking your plane, the rest is just up to personal preference. But if you pay close attention to these and pick your plane carefully, you will find that radio controlled flying is a great way to spend your time. It is a very rewarding hobby, and it can last you a lifetime if you choose planes that are compliant with your level of skill. After all, you dont want to go out on your first flight and then crash your plane directly into the ground or a tree. So choose your first plane carefully, and you can avoid being immensely frustrated in the future.

Remote Controlled Cars Make A Fun Hobby

If someone is interested in radio controlled hobbies, they almost always start with a car. Unlike a boat or a plane, cars usually wont be completely destroyed if they fail. It is very easy to make a basic radio controlled car, but as you do it you will discover that there is a huge amount of knowledge that can be gained. As you gain this knowledge, you can start to use advanced techniques to create cars that are stronger, faster, or more efficient than your previous ones. You can throw one together in a few minutes, or you can spend months creating an amazing car with superb speed and handling. The amount of effort you put into it is entirely up to you.

If you are just starting with radio controlled hobbies, it is probably wise to just buy a pre-made radio controlled car. You can buy these in toy shops almost anywhere. It may be slow and clumsy, and it may not satisfy your technological urges, but it is a good place to start. Play with it for a couple of days, and then take it apart. Look at the way the motors are connected to the wheels, and look at the general architecture of the car. After you understand it all, you will have much better luck when you start to build your own. You may even be able to use a few parts, such as the body of the car or the radio equipment. The motors will probably not be as strong as you would like.

After you have gained this essential basic understanding of the way that radio controlled cars work, you can start on whatever you want your next project to be. For most people, their goal is to build a model car from wood or plastic, install the electrical components, paint it, apply decals, and basically get it looking as good and performing as good as possible. Others may want to build an incredibly fast remote controlled car to show off to friends. No matter what you want to do, you will only be able to achieve it if you take it one step at a time and learn everything there is to know about remote controlled hobbies.

Many different resources can help you out along your way to becoming an expert in radio controlled hobbies. You will probably be spending a lot of time researching all of the different information that you need. You can find it all over the internet, including many different tutorials. For more specific questions, you can go to community groups and forums. This is where people from all over the world gather together on the internet to discuss their hobby, support each other, and brag about their latest accomplishments. Usually they are very welcoming to newcomers, especially if you are very clear and polite in asking your question.

Radio controlled cars dont have to be without competition. If you want to put your car up against those of other enthusiasts, you can find many different races and exhibitions around the world. Just do a quick internet search, and find out what the nearest option is. You might have to take a weekend trip, but it will be worth it to be around those who are as passionate as you about what you are doing. These meetings may include races, or just a good old convention to share tips and tricks with other radio hobbyists. You would be surprised at the large amount of information that you can learn from the people who go to these events.

Starting a new hobby may be daunting at first, since there is a wealth of information that you probably know nothing about. However, if you just get started with the basics and use all of your resources that are at your disposal, you will be able to succeed.

Where To Find Guidance on a Radio Controlled Project

Undergoing the entire complicated process of building a remote controlled model is a very daunting thing to do. If you are passionate about getting to know radio controlled hobbies better than anyone else, then you will definitely have to start somewhere. However, with no previous experience you will probably run into quite a few hitches as you work on your project. For example, if you are building a model airplane and you plan to install a motor in it, there are countless things that could get in your way. Maybe you dont understand how exactly to piece together the wings. Maybe your plane catches fire every time you try to run it. Maybe you dont even know where to start.

No matter what is getting in your way, there are many ways that you can get past it. A good start for any radio control project is to find plans or blueprints that you can follow for the entire length of the project. You can buy kits that include all of the pieces, or you can find plans on the internet and cut your own wood. It just depends on how much effort you want to put into the project. After you have the plan (which should include diagrams and exact measurements), you can begin to gather supplies. If you stick with everything that the plan says, you will be much less likely to hit a snag. As you work, you will learn skills required to make personal touches to the plan.

The best way to have constant support no matter what goes wrong is to make friends with some sort of expert in the field. Is your uncles wifes cousin a fanatic for remote controlled hobbies? Get his phone number, call him up, and see if you can get some help. Most of the time people will be more than happy to share their knowledge with someone who is interested in similar things. You can also meet radio control gurus at conventions, races, or even supply shops. It is good to know someone locally, since you can meet wit them and show them whatever your problem is, and they can even glue a few pieces together, or do whatever else needs to be done.

For small inquiries that dont require hands-on assistance, you can use the internet. There are numerous online communities for radio controlled hobbies, which come in the form of message boards, mailing lists, or blogs. These can be found with a quick search engine keyword, and are usually home to numerous extremely intelligent people whose combined knowledge covers pretty much everything about radio controlled hobbies. If you ask a question of these communities, you will almost immediately receive multiple helpful responses. Using advanced technology like digital cameras and microphones, you can get an even more personal response.

Finally, you can get your information from a good, old-fashioned book. Libraries are full of so much knowledge, it is surprising that they go so unappreciated in todays culture. If you go to the library in search of books about radio controlled hobbies, you will find numerous resources that will help you out greatly. Your query could range from the electronic aspect to the construction. In a similar vein, you can subscribe to magazines that regularly cover this sort of hobby, giving new plans, details, and advice for all subscribers.

If you use all of these different resources, you should have no problem building and enjoying the radio controlled hobby that youve always wanted. Embarking on the journey alone is definitely not advisable, since you will have to do many things that no normal human is faced with. From cutting the wood into precise chunks that will make up the different components to installing the electrical parts, each step requires close attention to detail. It is good to have backup in case you dont quite understand something.

Finding Components For Your Radio Controlled Hobby

There are two approaches to building a radio powered model of a vehicle such as a boat, car, plane, or helicopter. The first is to buy a kit that contains everything that you need. If you buy this, all you need to do is snap everything together, or glue it into place. This is a great place to start for anyone who is interested in radio controlled hobbies. However, after you make this first project, you will probably want to move on to the more advanced method of construction. This involves finding very precise plans for a radio controlled project, and creating it from scratch. You will use wood, power tools, and glue to get your miniature vehicle looking as close to the real thing as possible.

Throughout the course of building a radio controlled project from scratch, you will almost certainly find yourself lacking certain items. Whether your exacto-knife breaks or you accidentally set your wood on fire, you should always have a vendor that you can fall back on for your supplies. There are many different choices for people who you can buy components from, both local and long-distance. Usually hobbyists will end up finding certain people who they are comfortable buying from, but here you will find some of the main ones that you should investigate before you decide on a single one.

Local hobby stores will almost always have some form of whatever you want. If you just need a quick substitute for some item that you lost or broke, then craft stores will have what you need. You can find knives, some kinds of wood, paint, model glue, and various other small items. However, most of the time you wont be able to find products that are specifically geared towards radio controlled hobbies. You will have to decide for yourself whether you can make do, but more often than not you will want to hold off and buy specialized items that will allow for the ultimate in precision.

To find tools that are specifically used for radio controlled hobbies, you should look online for specialty stores. There are many web pages that sell (or even just point you towards) items that are perfect for the project that you are working on. Usually they will have user reviews so that you can see what kind of response the items get from radio controlled hobbyists who use the item for the same thing that you need it for. Before you buy from a certain site, you should search on the internet for experiences that people have had with it. How fast is their shipping? Do their customers ever receive broken items? These things are rarely problems, but you should still be sure before you order.

EBay has quite a few tools and parts that can be useful in the making of a radio controlled project. If you know exactly what you are looking for, you can usually find it for less than any other site. However, if you want to look around for something and find out about the best items to use, eBay is probably not the best choice since it doesnt provide user reviews and recommendations for the items. This is why it is a good idea to do your research on a site that is geared towards radio controlled hobbies, and then find the same items on eBay after you have decided which ones will work best for you.

If you buy high quality parts for your remote controlled project, you will probably not have to buy them again. If you buy cheap and low quality parts, they will break very soon and you will end up buying them over and over again (which will ultimately be more expensive than if you had bought the nice parts to begin with). So do the research, and find out about the best tools and parts to suit your needs.

The Process Of Building A Radio Controlled Plane

People can spend hundreds and hundreds of hours on building a radio controlled plane. It is a hobby that is very pervasive throughout the world, and no matter where you can go you can find at least a few die-hard enthusiasts who will continue to devote their time to creating the best radio controlled plane possible. Some people get started on the project on a whim, without putting proper thought into the amount of effort that it will take to get finished. If you are thinking about making a radio controlled plane, you should know exactly what will be required of you. You may decide that it is too much work for too little payoff or you may be passionate enough to stick with it and give it a try.

The first, and the longest, part of the process is to build the model. By itself, the model is no more than a bunch of wood, glue, and maybe a bit of metal in the shape of a plane. How much effort you spend on this will be dependent on what your goal is. Do you just want something that will get off the ground? If thats the case, the style wont matter too much to you. You can build a very basic box that will be able to lift off. However, most of the time hobbyists will create lifelike representations of existing airplanes. This involves creating an airframe out of a light material such as balsa wood, then covering up the sides with some kind of plastic. The dimensions are usually scale representations of whatever plane the model is based off of.

After the basic model is built, the builder will begin to bring the whole project together by installing the motor and radio components. They should always be easily removable, in case they need to be replaced. Get everything fit in to make sure you created the model correctly. Usually, you will buy all of the motors and radio transmitters in one set, and by following some quick instructions you can get it all pieced together. After you have installed it once to make sure, you should take it all out and finish the details of the model. Add decals, paint it, and do anything else that you have in mind. Once that is done with, put the motor equipment back in one last time.

Unless you have followed directions word for word down to every last detail, your plane probably wont be ready to fly right away. At this point you can take it out to a field or a park and attempt a takeoff, but you shouldnt hold your breath. You might have been lucky enough to get it right the first time, but you will probably need to make some tweaks. This is by far the most frustrating part of making a radio controlled plane. You will have to determine whether it is a problem with aerodynamics, or whether your radio equipment simply isnt working. If you are stuck on this step, its a good idea to consult a radio controlled hobby expert to see if you can get a diagnosis.

The process definitely takes a lot of time and a lot of effort, but it is worth it in the end. When you can make a flawless takeoff and maneuver the plane through the air, you will be proud of the work that you have done. While you are toiling over building the model, getting everything to work right, and getting it to take off, just imagine that first moment when you are able to take off. Go out to the park one day, and see if you can catch another model plane enthusiast out flying his or her plane. Take a turn, and get a taste for what is coming in the future. If you keep reminding yourself of that, you will be able to remain inspired.

Getting Started With Ham Radio Control As A Hobby:

Ham or amateur radio as a hobby involves some hard work in the form of getting licensed, and acquiring knowledge of the technical details. The hobby itself starts in the first step by one getting the ham device. Selection of a good ham radio is best done under the guidance of a person who knows about the radios well. More than that, one must know the local laws and rules with respect to the ham operation.

Getting to know your ham:
It is important to know about hams and, to know about your own ham as soon as you feel the urge to buy / assemble one. If you want to know about the ham, then again, internet, books and other hobbyists are all good places to start with. If you know no technical details of the electronics but find yourself fascinated by the idea, then it is time to learn a bit of jargon in the field.

So, if you do not know something, you should come out and seek answers either from those who might know or from resources like the library or the internet. One must spend some time and effort to learn about the hobby that one wants to pursue. Just a wish is not a good enough reason to pursue a hobby. One needs more than just a wish to be able to pursue an activity as a hobby. So, recognition of the hobby and the right kind of activity that suits you is important.

Ham operation can be taxing and sometimes it can be tiring in spite of the modern equipment that does the scanning on its own. It is like the astrophysicist searching for some communications from aliens. If that idea grabs your attention, then this hobby will be to your liking since the activity is virtually the same, except for the helpful fact that we know there is someone who exists for sure, and one gets more than just radio signals of unknown nature. You get interaction from real people, from out there in the world, who live in flesh and blood as you do.

Your choice of equipment depends on how involved you are, and what your budget is that you can afford to invest in a ham equipment. There are good stores out there that sell ham radio at a reasonable cost. Again, as usual, its wise to chat with those who are ham radio operators, and also to visit and know the prices from various shops that sell ham radios to be able to select the best deal.

The cost of the radio equipment that can connect to longer distances will be higher than the ones that have a lesser range. Moreover, the recent advancements like digital voice transmission and such can be more costly than the simple Morse code wireless telegraphing model.

Getting licensed is the next hurtle. The amateur radio operator license exam does not require Morse code proficiency any more as it is has been allowed to be dropped as agreed in 2003 in the World Radiocommunication Conference in Geneva. The test will include the knowledge of ham etiquette, the communication laws that apply internationally as well as in your region and such. Once licensed, one is free to use the allotted bandwidths and is allowed to change or modify the equipment within the limits imposed by spurious standards.

Sowhat are you waiting for? Go get a ham and get your license: get going!

Resources For The Beginner Who Wants To Pursue Radio Controlled Hobbies

If electronic gadgets fascinate you and you want to do more than just use them, then you are a great candidate for pursuing a radio controlled hobby. If designing and assembling electronic devices is your fascination then you will be interested by RC models, whereas if you are more interested in wireless transmission and making communication contacts with people around the world, then you are more cut out to pursue hams.

These overlap many times, and most ham operators have a flair for radio controlled models, and vice versa. This is because they are attracted to anything that concerns radio waves. The best resource available to a beginner in radio controlled hobbys is the internet. It is a storehouse of information with valuable bits of knowledge on all aspects of the hobby. But interestingly, as opposed to amateur radio which is far easier to search for online, searching for RC model enthusiast groups is a bit tricky! If you try to use any search engine to search for remote controlled toys, you will find scores and scores of sites listed, most of which deal with sales of the toy grade or sometimes hobby grade models.

This does not mean that one wont find good resources on the subject online, just that one might have to change the keyword to find the best results. One other way is to use the online communities and forums which can be indispensable tools for connecting to people with similar interests. There are dozens of Yahoo!, MSN, AOL, and Google groups for this purpose. In addition to this, there are online communities, blogs and friends network sites. These will be good places to start. There are numerous groups and one must try to find one with people close to home as well as those that have activities related to the hobby. One word of caution always applies that one should never reveal personally identifiable details online unless you are confident in what you are doing.

The benefit of online search is that distance is not a factor, and there are virtually no other restrictions. You may also meet with more experienced hobbyists who can guide you pretty well in pursuing your hobby. Talking to experienced hobbyists can help you make a good decision, and can help you learn a lot. There is a lot available online and someone must know where and how to get to the useful information. You must try to collect information on the history of the hobby that you are pursuing, and the current issues and contemporary relevant things with regard to the hobby.

You should consider the amount of time you want to devote to your hobby. Time is an important aspect that one needs to consider before pursuing ones hobby in a serious manner. Without adequate time available on hand, one cannot pursue the hobby of amateur radio. RC hobbies involving toys and devices also requires some time.

Financial investment should also be considered. This is one important criteria and is the bridge that changes you from I want to be a radio hobbyist to I am a radio hobbyist. Amateur radio sets are available in ready-to-use form. The costlier models usually have a longer range and better quality. On the same grounds, the better and latest RC models will require a considerable investment.

Just use all of the resources at your disposal, and you are sure to find that radio controlled hobbies are very fun and rewarding.

Activities For Radio Hobbyists

Amateur radio or ham is largely a hobby activity. The majority of thel hobby time is spent on making contact and having conversations with people in distant regions and from different cultures. Two way communications, identifying their location and station, zone, region and place is the usual custom. This is always followed by other casual communications. If the contact is made for a contest to make two way communication with as many stations or ham radio operators as possible, this all the information that is shared.

DX-ing and DX-peditions:
An amateur radio operators main hobby is to make contact with as many stations as possible from as many parts of the world as possible. DX stands for Distant Stations. The DX-ing usually is followed with the QSO. (a Q code., see below) which means a conversation.

DX-peditions are different in the sense that they are expeditions organized / planned solely for the purpose of making contacts with some special or rare stations and regions. Some people travel long distance just to make contact with some unrepresented region or place.

Radio Frequency scanners available now a days form the tool of great use in these attempts. The radio scanner scans for signals until a strong signal is found and so on.

QSL cards:
The Q code is a standardized collection of three-letter message encodings, all starting with the letter “Q”, initially developed for commercial radiotelegraph communication, and later adopted by other radio services, especially amateur radio. In todays audio signal transmission age, the Q codes are not essential. but still in use and are viewed as a sort of tradition.

As a part of DX-ing and DX-peditions the QSL card or the proof of contact card is shared. QSL is one such Q-code that means I acknowledge receipt. The common practice was that the ones who made contact at a particular frequency exchange a QSL card in the mail to confirm their contact and conversations. These QSL cards can be used as a proof of their making contact and amateur operators who make contact with a certain number of other amateur radio operators in a specified time is awarded. Moreover, they are distinguished and honored since they are deemed to be efficient amateur radio operators.

Remote region contacting:
Some countries have less amateur radio operators, and making contact with these is considered special. So, when a radio amateur from these regions makes contact, other ham operators flock to make communication with this / these hams. Making contact with these less represented places has its awards and special considerations in the award programs.

Hamfests:
Social events for the ham families and friends. Its something akin to the family oriented social fests where there are sales, exchanges, meetings and fun. Similarly, the fest is filled with selling and exchanging hams, meeting real life ham friends and fun events for a day or sometimes over few days.

Discussion groups and Nets:
Ham operators form a discussion group based on common interests other than ham or it can also be a ham related discussion group and they can form nets or networks.

If a radio hobbyist gets involved with all of these different activities, he or she is sure to never be bored. Look into some of them, and see if you would like to get involved.
