First let's take a look at the radio tracking collars. Radio tracking collars consist of two different parts. The first part of the pet tracking device goes on the dog's collar and is constantly sending out radio signals. The second part of the radio system is the directional antenna or receiver which is constantly listening for the signal coming from the radio collar. The owner can tell if the dog is closer if the sounds from the antenna get louder or if the dog is getting farther away because the sounds from the antenna are getting softer.

I know what you're thinking...You've seen this on an episode of the Discovery Channel. Yes, you're exactly right. This radio pet tracking device is exactly the same technology that researchers have been using for years to track all kinds of animals. It's the same thing just now are able to purchase this technology for your very own pet.

There are some major problems with the radio tracking collars which make GPS dog collars a very attractable alternative. There is no question that the cost of such systems is very high. These devices are very new to the arena of pet owners and so this has kept the price very high for the time being.

So I'm guessing that you are now worried that you will not be able to afford a pet tracking collar. Well cheer up because GPS dog collars are very effective and cost much less than radio tracking collars. These GPS dog collars are very small in size actually can be used on virtually any pet. New features have made GPS collars even more useful. With higher end models you can call the GPS dog collar from your cell phone and then be instantly told where your dog is. It is also possible to do real time tracking of your dog via the internet. The main drawback to this technology is that you must be in an area with good cellular reception. Another possible drawback is that batteries must be changed every couple of months. ]]> http://www.articlecontentdirectory.com/communications/satellite-radio/getting-you-started-with-gas-powered-rc-car-or-truck.html http://www.articlecontentdirectory.com/communications/satellite-radio/getting-you-started-with-gas-powered-rc-car-or-truck.html Thu, 24 Apr 2008 00:00:00 -0400
Are you new to the RC racing world? Read this article to get yourself started in this fast paced hobby.

There are many ways on how to start with gas-powered RC car or truck. There are many realistic features offered by these remote-controlled cars and trucks. They come in a variety of styles and types in the industry. In choosing one, there are many considerations you should take before eventually owning one.

Radio-controlled cars and trucks lack the power and running time. But if you want to consider, you can convert them into gas powered RC cars, with the use of nitromethane-based fuel. This fuel provides RC cars a level or realism or performance, which are absent on other battery-powered vehicles. Aside from this, they are also highly customizable making it possible for you to integrate RC car accessories and personalize them. There are options of engines and transmitters available to allow you to choose one depending on how you’d want the RC car works.

To help you begin in finding the right gas-powered RC car, the following are the factors you should consider:

1. Engines. The most important aspect in a gas RC car, you can choose from the variety of engine models available to choose from. Generally, most RC cars use a specific type, which is commonly called as "glow" engine. It is a 2-cycle combustion engine, which creates power to the RC car preparing it for realism that also produces exhaust in the process. In replacement of spark plugs utilized by automotive engines, a "glow plug" is used for this engine. It is being heated in turn by a "glow starter." The heat will be held by the "glow plug" to which this is now used to fire engine strokes for rest of the running power.

2. Fuel. Just like the actual gasoline used in automobiles, the nitromethane-based gas fuel the RC cars. The fuel mixture is formulated with special lubricants so that it protects the engine from the excessive heat produced by the combustion process. The lubricants are the same with the gas-oil you use with your small engine equipments or some chainsaws. Accessories such as a special bottle pump may be needed to get nitro-fuel into your fuel tank of the RC car. Filters are also used on these cars and the same with your automobile they require replacement at a proper time interval.

3. Radio. Radio controller is used to control the RC car and could be same type used on electrically-powered RC cars. It is radio controller operates on 2-channel system that needs batteries to make it work. Additional batteries would be needed to power the receiver though there are other receivers that are fed from the motor itself.

4. Sport or competition. This is an aspect you most considered when choosing body style. There are different options for you; you have choices from sedans, trucks, buggies, stock cars, and other popular car models. These are basically available in two versions: sports, and competition version. Sports RC cars typically cost less than the car you intend to race, which of course would need more power and higher speeds. Ball bearings and oil shocks are some of the advanced options included for the competition RC car version.

Depending on the type you need, RC car kits and ready-to-car or RTR kits are available. If you are a beginner, RTR kits are what you need as this comes out of the box ready for the fuel. RC car kit, on the other hand, requires heavy work but allows you to decide how they would be put together. ]]> http://www.articlecontentdirectory.com/communications/satellite-radio/flying-hobbyist-aircrafts.html http://www.articlecontentdirectory.com/communications/satellite-radio/flying-hobbyist-aircrafts.html Wed, 23 Apr 2008 00:00:00 -0400
These flying models of aircrafts comes in all sorts of designs ranging from vintage radio controlled model planes to modern fighter jets like the F16. Most of them resembles the real plane closely because their main purpose is to look like the real piloted aircraft. However, every rule has its exception. Some of the more fancier models of aircrafts are made to model birds and dinosaurs or even a witch on a flying broomstick.

The construction of these aircraft models that have the ability to fly are made very different from models that are static and cannot fly. These flying models borrows heavily on techniques from full-sized vintage aircrafts even though these flying models may or may not be vintage aircraft models. These models also use lighter materials in their construction because it aids in the aircraft light weight used for flying. The materials used might consist of forming the frame of the plane model with thin strips of light balsa wood. Decorations for the body frame may include very thin and light materials and then doping the fabric to form a light and sturdy frame which is also airtight. Sometimes thin paper is used instead of fabric. Since these models of aircrafts will need to be launched in the air, they employ robust designs patterns adapted from vintage aircrafts and use solid sheets of wood to form the spars and the ribs for thw ings and the tail surfaces.

Numerous of these flying models are built from scratch. The hobbyist goes to a model plane shop and picks up a kit or he may choose to go to a hardware store and purchase all the parts he needs. Plans for building such aircrafts are widely published and can easily be found on the Internet. The Internet is a major driving force for the aircraft model hobby because it allows people from all over the world to share their aircraft model building experiences and also to post photos of their own model aircrafts.

In recent years, more and more aircraft models have been manufactured to cater from the increased demand for this hobby. Aircraft models range from the vintage aircraft plane models to the latest fighter jets models. There are a lot of different models out there to suit the varying needs of different collectors. ]]>
