radio control Harley Davidson motorcycle

An exciting radio control Harley Davidson motorcycle is now available and who else but the folks at Harley Davidson would put their nameplate on radio control vehicles as realistic as this?


The authentic styling of the motorcycles makes them appealing to a wide variety of radio control enthusiasts. The most popular version of the motorcycles is the 1:3 scale made by New Bright.


For the collector, this radio control Harley Davidson motorcycle shows off a high level of detail on the 28 long framework and accompanying accessories. It has realistic brake lines, chrome pipes, true rubber tires, and mirrors you can actually see a reflection in. The motorcycle also has steel handlebars and a folding steel kickstand along with a variety of other plated and metal parts.


Another feature the collector will like is the realistic sounds the motorcycle makes including rev, idle, gear changes, and a horn. For a quieter bike, these sounds can be turned off using a volume switch on the gas tank. The motorcycle also comes with its own display stand to show it off with.


For the hobbyist, the front and rear spring suspension help give the radio control Harley Davidson motorcycle a smoother ride making it able to navigate slightly rough surfaces. The control has forward drive, left and right steering, and a brake. The motorcycle is powered by a 9.6 volt NiMH battery cartridge that takes about 4 hours to charge and lasts through 30 minutes of continuous use. The dual joystick controller takes 6 AA batteries for its power and has a range of about 100 feet.

Harley Davidson

For everyone, the radio control Harley Davidson motorcycle in 1:3 scale comes in two models: the Fat Boy and the V-Rod, each one available in a couple of different color schemes. If the large size of the 1:3 scale isnt what you are looking for, New Bright also makes a 1:6 scale radio control Harley Davidson motorcycle that you may find more appealing.


These naturally dont have quite the detail of the 1:3 scale, but they do come with their own mix of realistic features. They have start-up, rev, and horn sounds and the frame sits at about 16 long. The radio control has forward, left, and right steering. The bike is powered by a 6-volt rechargeable battery pack.


Still too big? You may want to check out the mini radio control Harley Davidson motorcycle. This one measures 4 long and comes in the Road King, V-Rod, Fat Boy, Softail Deuce, and Police models. The control has a 10 radius and works in forward, reverse, right, and left. The motorcycle recharges in 45 seconds on a stand, which looks like an old-fashioned gas pump, and the charge lasts about 6 minutes. The bike charger requires 3AA batteries and the controller takes 3AAA.

Typical radio control car gas

The lubrication in the fuel can also help keep the running temperature of the engine desirably low. But you cant rely on too much of a good thing.


While more oil may keep temperatures even lower, it also lowers the ratio of nitromethane in the fuel, which is responsible for the actual amount of power transferred to the vehicle. But putting in too little oil to make room for more of the nitro can result in overheated, worn down engines in which extra power wont do much good.


Typical radio control car gas has a nitro content of about 10% - 20%, but many enthusiasts experiment with their own levels to achieve the mixture of power results and long engine life they are looking for. Larger radio control cars may benefit from higher nitromethane ratios, but remember the warning about too much of a good thing.


There is certainly a level of diminishing returns where more nitromethane doesnt convert to more power and just takes up the space where precious lubrication should be. Its a give and take relationship that takes quite a bit of mastering if you are going to experiment with your own fuel rations.


How does this radio control car gas work, anyway? It uses combustion within the engine to transfer power from the fuel into mechanical power. The combustion chamber has what is known as a hot spot created by a glow plug (similar in concept to a spark plug in regular vehicles).


The pistons create compression, the glow plug gets hotter, and the combination of the two results in the necessary combustion begin to burn and keep burning the fuel to power the engine.


So if gas powered radio control cars strike your interest, remember that the fuel is the key to running and maintaining a powerful engine. And also remember to use the proper safety and caution with the flammable materials involved.As long as the combustion cycle continues to receive the oxygen and fuel it needs to keep the process going, the radio control car gas will continue to burn and power the engine.

Hobby RC Car

Having said all that in favor of electric powered hobby rc cars, I will mention that they don't have nearly the high performance features of their gas powered counterparts but you can improve that with aftermarket parts and engines upgrades. Stock models, out of the box, will usually run up to 10 minutes before the batteries need recharging, which takes about 15 minutes. By having a second battery pack fully charged and ready when the battery runs low will save down time and after all, we want to be playing...not waiting!


If this is your first hobby rc car, you may want to get a Ready-to-Run (RTR) unit complete with a 2-channel radio so you can be on the road in about an hour. Speeds of between 20-30 miles per hour are common and Nikko radio control cars offer a good variety, but they're certainly not the only manufacturers out there. These types of vehicles are usually targeted at new modelers and "backyard" drivers, rather than racers bent on winning organized competitions. But again, as your skills grow, you can improve your hobby rc cars speed and operation with upgrades like a new motor.


Motors are classified as either Stock or Modified. Stock motors have plain bushings, fixed timing, and 27 turns of machine-wound wire and it usually comes with the car kit. Modfied motors have ball bearings, custom winds, and adjustable timing...offering very different performance specs for your radio control cars. Fewer winds usually equals greater rpm's and shorter run time while more wire strands usually means smoother acceleration. Some of the very best (and most expensive) electric motors available are made by a company named Hacker Brushless.

Great RC Battery

When you want an RC battery for your radio control car, truck, boat, heli or plane, you want top quality at reasonable prices. I've spent many hours searching the Internet for these valuable batteries from reliable suppliers and I think you'll be pleased with the results.


Bear in mind that a NiMh battery is superior in many ways to the equivelant NiCd battery in that it's much lighter, the charge lasts longer and nickel-metal hydride is friendlier to the environment because it does not contain the toxic chemicals found in other batteries. They are however more expensive but the price keeps dropping now that LiPoly cells are on the market.


I trust that you'll find all that you need here but if you don't, then feel free to contact me and I'll try my best to supply you with the battery of your choice.

Nitro RC cars

Radio Control System In hobby quality nitro RC cars the radio control system is fully proportional. This means that the speed of the car can be finely controlled. You can go at 0% to 100% full speed, and any speed in between, just like a real car. The same goes for steering the car. You can turn left gently, or turn left aggressively. You can turn right gently, or turn right aggressively.


Radio control parts that are installed inside a nitro RC car:


1. Receiver


2. Fail safe


3. Servo for carburetor and brakes


4. Servo for steering


5. Receiver batteries


6. On/off switch Transmitter - The transmitter is what you hold in your hand.


Your left hand is usually used to squeeze the trigger, which controls the speed of the car. The more you squeeze, the faster the car will go. If you want to stop or brake, push the trigger towards the opposite direction. Your right hand controls the steering wheel on the transmitter. This controls the direction of the car, whether to turn left, right, or just go straight. The stick type used two sticks. The left stick is used to control the speed of the car, and the right stick is used to steer the car.


The pistol type uses a trigger and a steering wheel. The trigger is used to control the speed of the car, the wheel to steer the nitro RC cars. The transmitter needs a 12-volt supply to run, usually via eight AA sized batteries. Receiver - The receiver is a small rectangular device mounted on the nitro RC car. It has a wire (usually 19) that acts as an antenna to receive signals from the transmitter. Gas RC cars need a 2-channel radio control system. 2-channel means that there are 2 servos connected to the receiver. The receiver needs a 6-volt supply to run, usually via four AA sized batteries.


Tips: Never, ever, cut the antenna wire. I know the wire is long but still, resist the temptation to cut it. To avoid radio glitches, keep the receiver and antenna as far away as possible from the 2-stroke engine. Servos - The servos are small mechanical motors with decide the speed and direction the car will travel. Nitro RC cars have two servos, one connected to the carburetor, another to the steering mechanism. The servo connected to the carburetor controls the speed of the car. It also controls the braking mechanism. The second servo is connected to the steering mechanism, controlling the direction of the cars front wheels. Frequency Crystals - The transmitter sends signals to the receiver on a specific frequency. Removable frequency crystals, located at both the transmitter and receiver, determine this frequency.

Download Free Flight Simulator

So your looking for an simulator? There are so many available now it can be very confusing but this article will help clarify things.


To start with I will suggest that you do yourself a huge favor and download free flight simulator FMS (Flight Model Simulator) because it's an excellent tool if used properly. The big mistake that so many people make is to believe that the simulator will teach them to fly. A simulator cannot teach anything, whether you download free flight simulator or anything else. They are simply not programmed with that ability. Many software packages have a built-in tutorial that allows the user to step through the functions of the program as it explains how to use each one. The RC flight simulator does not have this feature.


For instance, it does not explain that stick movements should be gentle and only enough to get the model to perform a maneuver. It does not explain that the model must be controlled into and out of a turn with the ailerons. These are the functions of an instructor. The flight simulator is a tool to practice the maneuvers that have been taught by an instructor. A student pilot, especially a beginner, can develop some very bad habits while using a simulator that are difficult to break later.


There is a young pilot who taught himself to fly using an RC flight simulator (I don't know if it was a download free flight simulator or not). When he arrived at the field to get some one-on-one instruction, he had already developed some bad habits. He managed to fly circuits around the field maintaining a good altitude although a little low according to the instructor. The problem that he had developed was his execution of the turns. He would make the turn with a series of very quick movements of the aileron stick. This was obvious by the erratic banking into the turn. The instructor showed him on several occasions how to make the turns smoothly with gentle movements of the sticks. He is now flying an aerobatic plane and his turns are only slightly less erratic.


For beginners, RC flight simulators are excellent tools for building spatial orientation, motor skills, and confidence. For more experienced pilots, flight simulators, even the download free flight simulator, can help in building motor skills required in doing the more difficult maneuvers. The amount of benefit that the pilot can gain from the simulator depends entirely on how well the simulator emulates the model. On most simulators, the flight characteristics can be adjusted so that it more closely emulates the "feel" of the model. None of the flight simulators have progressed to the point that the flight physics are perfect but they are close enough that they can be of significant benefit.


Dne of the most difficult things to master for the beginning pilot is approach orientation. There is a natural tendency for the beginner to move the stick in the direction he wants the model to go. When the model is moving toward the pilot, the aileron and rudder controls are reversed. This means that in order for the model to turn to the pilot's left, the stick must be moved to the right. Using a simulator, even a download free flight simulator, allows the pilot to practice approaching maneuvers for hours on end so that it becomes second nature to move the stick in the correct direction for the model to take the desired flight path. After approach orientation has been mastered, all other maneuvers start to become easier to accomplish, especially landings.


The primary benefit of flight simulators, including FMS download free flight simulator, is that of building motor skills. The pilot, whether a beginner or experienced, can practice specific maneuvers for hours without having to be concerned about weather, time of day, temperature, or number of people at the field. The motor skills that are developed through hours at the simulator are basically the same as "muscle memory" in golf. This means that the skills are related more to the muscles reacting to a simple command than the brain sending a series of commands to the muscle.


For instance, the pilot wants to perform a snap roll with a Giles 202 model. He thinks "snap roll" and his fingers simply move the sticks to the appropriate position rather than his having to think in what position the sticks need to be. The end result of the muscle memory is where modelers get the term "feel" for a model. Since there is no positive feedback system built into a transmitter, there is not true feel for a model. The feel of the model comes from the difference in the expected feel based on muscle memory and the actual feel from the movement of the sticks.


Many beginners do not progress as well as others simply because of a lack of confidence. This is especially true if the student is not able to fly very often due to conflicts in scheduling time to devote to learning to fly. With each trip to the field, he must re-learn some of the things that he has forgotten during his absence from the field. He must again reinforce his motor skills and regain his muscle memory or feel for the trainer. Since his progress may be much slower than that of other students at the field, he may become frustrated and much less confident. The download free flight simulator allows the beginner to practice what he has learned to maintain or improve his motor skills and not lose his confidence. When he goes to the field, he will subconsciously think, "I can do this."


A few years ago, there was an article in one of the leading R/C magazines about the benefits of an RC flight simulator. There was a story of a young man who flew a club trainer a few times then bought a flight simulator. He knew enough of the basics to be able to hone his skills on the different model configurations offered on the simulator. After several months of practicing on the simulator, he went back to the field and flew every model at the field including a ducted fan jet plane. He had no problems with basic maneuvers because he had developed the skills required through many hours of practice with the simulator. This is an extreme case but it shows what can be accomplished through using a simulator, even FMS download free flight simulator, if the basic methods have been taught.


If pilots get proper instruction and use the flight simulator to practice what is taught, it can be of significant value in learning to fly or to perfect various maneuvers. It can greatly increase the "stick time" that the pilot is able to achieve in given period of time. It is a tool that if properly applied can help a pilot to progress at a much faster rate than normally possible. Above all, it is up to the pilot to make sure that this tool is properly applied by getting the right kind of instruction and not try to learn on his own.


If, after you download free flight simulator FMS, you want to explore commercial versions, then be sure to take a look at the hugely popular Real Planes G3 simulator below...and enjoy!

READY TO RUN (RTR)

Maybe the best way to enjoy the simplest in radio control is to go for an all inclusive cheap radio control cars package.


You can get these from toy stores, hobby shops, online, or just about any of your discount department stores. This form of RC car generally comes ready to ride straight out of the box. The car comes with its own radio controller with one or more frequencies, rechargeable batteries, and the car itself. These come in various scales, colors, and complexity. You can purchase cheap radio control cars anywhere form the size of a matchbox on up.


Perhaps the best part about these simple cars is that they dont have smaller, loose parts and are therefore great for small children. Many of the top-notch RC enthusiasts cut their teeth on easy to find, cheap radio control cars. You can get into one of these for anywhere from $15 to $100, depending on what bells and whistles you want.
