Radio Control Batteries Info

Radio Control Batteries FAQ

How do radio control batteries work?

When a load (motor, receiver, anything that takes power) is connected to a battery, electrons travel from the positive terminal to the negative terminal (also referred to as electrodes). The flow of electrons causes a chemical reaction in the inner electrolyte of the battery providing power to the load.

In rechargeable batteries, the chemical reaction can be reversed. This, in essence, puts things back the way they were. Thats why a rechargeable battery can be used over and over. By charging it, you just keep reversing the chemical reaction allowing it to start over.

What types of batteries do radio control vehicles use?

There are a few common types of radio control batteries:

Zinc-carbon This is the technology of inexpensive dry cell, non-rechargeable batteries such as AA, AAA, C, and D. Zinc and carbon serve as the electrodes while an acidic paste serves as the electrolyte.

Alkaline This is the technology of the more expensive dry cell, non-rechargeable batteries. Duracell and Energizer are two of the most popular manufacturers of alkaline batteries. These batteries have zinc and manganese-oxide as their electrodes and an alkaline compound as the electrolyte.

NiCd Nickel Cadmium radio control batteries are rechargeable with nickel-hydroxide and cadmium electrodes and potassium hydroxide as the electrolyte.

NiMH Nickel-metal hydride batteries are also rechargeable. They have a nickel hydrogen and a hydrogen absorbing alloy as the electrodes and potassium-hydroxide as the electrolyte.

Lithium polymer These have lithium nickel cobalt oxide-based and carbon based electrodes with a polymer biphasic electrolyte. (Say that ten times quickly!)

Whats the difference?

The obvious difference between dry cell batteries in relation to the others is that these types of batteries are not rechargeable. Once the irreversible chemical reactions inside them have occurred, they no longer react to create power.

In the world of radio control batteries, dry cells are used mostly for transmitters and receivers. The reason for this is that the radio components have much lower power consumption than the motor components of radio controlled vehicles. For this low power application with infrequent battery changes, many people would simply rather carry a spare pack of brand new dry cell batteries for replacement than deal with rechargeable radio control batteries.

The difference between the two most common rechargeable radio control batteries, the NiCd and NiMH, is not an exact science. The battery sizes used for radio control batteries come in both types, and there really arent many differences except that NiMh is lighter than NiCd.

NiMH have a higher discharge capacity and therefore may last longer depending on the size and application. They have virtually the same initial power and life cycles. One difference that interests a lot of people is that the NiMH batteries contain less toxic material and therefore create fewer environmental issues.

Lithium polymer batteries are creeping up on the market of radio control batteries. They claim higher power at lighter weight, no memory problems, and longer charge life.

What is the memory effect?

Rechargeable batteries do actually have what is commonly referred to as a memory. If a battery is consistently used at only partial capacity, the crystal structure of the inner chemicals will physically change, altering the capabilities of the battery. In essence, if you consistently use 25% of a batteries charge, it will change to only offer you 25% of its original charge.

For
radio control batteries

used in cars, running your vehicle until the charge is used up may not be so difficult. But if you use these radio control batteries in airplanes, draining the battery all the way down in your plane can obviously be disastrous.

Finally, lithium polymer batteries like those above never develop the dreaded memory effect and coupled with their light weight they are perhaps the ideal RC batteries availalbe today!

Model airplanes information

Essential Gas & Electric Model Airplanes Info

(All links open new windows)
Much of the attraction of model airplanes is how realistic the aircraft looks in comparison with its full size counterparts. Thanks to advances in technology, the components have come a long way in their construction. This is due in part to the fact that todays models are created from a variety of different materials, each having its own benefits.

Wood has always been a popular material for constructing models, and in the past most frames and components were wooden. Many model airplanes are still made from wood, especially by those model builders who want to completely start from scratch when designing and building their own aircraft.

Balsa wood is a common material used in model construction because of its ease of carving and lightweight properties. Wood is fairly inexpensive and easy to find, and once you learn the basic skills it is fairly easy to work with. The ready availability of woodworking tools also makes this a popular form of construction for gas powered
model airplanes

today.

Fiberglass has also been a common material for making model airplanes because of its sturdy nature. The drawback of fiberglass is that most model builders have to buy pre-made frame pieces for fiberglass construction. It just isnt a material that many people work with in their own workshops. But the strength it provides in relation to its weight makes it a great model aircraft material.

From those builders who like to work from kits, the main advance in airplane frames and components has been the manufacturing of injection molded Styrofoam & plastic parts such as GWS
electric radio control airplanes.

The molding of plastic certainly isnt a process you would want to carry out in your own garage, but this technology offers several benefits to the construction of model airplanes. The main benefit is that pieces and components can be formed that are very precise and of great detail. This results in smooth curves, accurate and well-defined detail, and a basically more aerodynamic and realistic model.

So what is injection molding, anyway? In injection molding, a detailed mold is created for model components. These molds are made in a variety of ways from detailed carving to creating a mold from an already formed piece. Once the mold is created, small plastic pellets are heated and the resulting melted plastic substance is injected into the mold. Injection is more effective than pouring because it gets the plastic into small crevices and very detailed parts of the mold. The plastic is then allowed to cool, and thus the part is formed.

Essentially, many models today are made from a collection of each of the types of materials depending on the components themselves. Basically, the type of material you will use for each of the parts of your aircraft depends on size and sturdiness of the individual part, the level of detail you want, and how much of your model airplanes components you want to build from scratch.

Whatever material you decide to use, have fun and happy building!

Hovercraft RC Introduction

All About Hovercraft RC
(Some links open new windows)






Hovercraft RC

are also sometimes called Air Cushion Vehicles or ACV. They can fliy like a plane but can float like a boat and can drive on land like a car all the while traversing ditches and small gullies. A thrust propeller pushes the craft forward on its bubble' of air. Rudders, like on an airplane, steer the direction of the craft.

This all applies to remote control hovercraft as well as the real thing. Needless to say, it's a unique method of transportation and an exciting hobby too!
The idea for a hovercraft is attributed to Christopher Cockerell (later knighted Sir Christopher for inventing the Hovercraft) when he was working with small boats.

Today they are used for many applications where people or equipment need to travel at high speed over water but be able to load and unload on land.

The hovercraft RC engine provides the power to drive large fans that blow air under the craft and the air is trapped by a rubber skirt that enables it to travel over a wide range of terrain.
Hovercraft RC, or remote control hovercraft have, until recently, been built by a small group of keen modelers but lately the hobby has become much more popular.

Model hovercraft, like many other RC models such as boats, airplanes, cars and helicopters, offer some problems in terms of scaling and operation when reduced from their full operating size.

The general operating principles remain the same but some modifications in the skirt arrangement are needed to make a successful remote control hovercraft replica of the original.

With hovercraft RC, the size of objects encountered on land and the wave size on water are two major problems when scaling model hovercraft. With gas engine driven craft there is also the added problems of water spray and dust, which will choke an engine and cause many running problems. The water poses a similar problem for electric powered remote control hovercraft.

Single engine hovercraft RC use one engine to provide thrust and lift for the craft with the air being split into two flows. About 30% of the air is used under the craft for lift and the rest of the air exits the rear of the craft over a rudder and provides thrust.

This creates simple model hovercrafts with the advantage that they can be controlled from a low cost 2-channel radio control system.
Twin engine model hovercrafts provide one engine for lift and one for thrust. The engines can operate independently and therefore require at least a 3-channel radio system.

The lift motor can be set using one throttle setting and the thrust controlled independently from another radio control channel. This type of hovercraft RC model generally provides better performance in terms of the height it can hover and the speed it can achieve.

We hope you find this information interesting and above all helpful while you research the exciting and unique hobby of hovercraft RC.

Franked or Free Congressional Mail Privileges

Franking, Franked or Frank is derived from the Latin word "francus" meaning free. Franked or free mailing of letters made their legal appearance in the United State on November 8, 1775, when the Continental Congress decided to give its membership the privilege of sending mail, free of charge, via a resolution that read: On motion made, resolved that all letters to and from the delegates of the United Colonies, during the sessions of Congress pass, and shall be carried free of postage, the members having engaged upon their honor not to frank or enclose any letter but their own. In place of a postage stamp, every piece of mail was to bears the registered signature or "the frank", of the congressman or senator and that means the USPS was to deliver mail at no cost to him. The first U.S. Congress enacted a franking law in 1789. At various times addition persons in the employ of the government were extended the privileges of free mail, including the President, the Vice-President, and the Cabinet officials. Because the privilege was most likely abused "Franking" was often called the "Franklin Privilege" while Benjamin Franklin was the U.S. Postmaster General. Franked mail covers are a popular stamp collectors item. That is, there are collectors who want franked letters of the Presidents, his Cabinet Officers, Generals and other important officials such as Congressmen and Senators. Stamp collectors and Autograph collectors are looking for the VIP signatures on these franked covers. Possibly the best use of the Franking privilege was during war time when Soldiers, Sailors, Airmen and Marines were allowed to send mail home to their loved one's by simply writing "Free" where the stamp would normally go on a letter. I assume and hope that this franking privilege is being done today by our military in Iraq and Afghanistan. Over the last 200 years U.S. Franked Mail Covers have been a popular Stamp and Autograph collectible.
