How do you make head or tail of this fairly detailed specification for your rc electric vehicle, without it resulting in your eyes glazing over? Help is at hand right here. Let us go through these features one by one and you will be overjoyed with enlightenment.

SP28404 brushless motor
This is the latest, more advanced, powerful type of motor, which is reflected in the overall (higher) starting price of the automobile in which it is fitted. The benefits to you are a potentially speedier, more dynamically efficient RC vehicle, with the added bonus that it should be simpler to maintain. RC automobiles with brushed motors however, are the classic, conventional types.

SP28405 brushless electronic speed control
The RC electric vehicle’s speed is regulated with an electronic speed controller (abbreviated to ESC). This is the component that controls the drive motor mentioned above, together with the general electronics. Most automobiles come integrated with the motor and ESC, but are separate purchases in the more enhanced set-ups.

Anodized aluminium centre drive joint
More commonly known as the RC electric vehicle’s drive shaft, this is the central rod that runs from the front to the rear of the automobile. Being made of aluminium makes it lighter without compromising on the vehicle’s overall stability and sturdiness.

Compact front/rear differentials
A differential is a device that in most cases incorporates gears and is designed to drive each pair of front and rear wheels with equal force, but still allows the wheels to rotate at different speeds. Differentials on good electric vehicles are high performance.

Suspension arms with adjustable Width
The suspension arms provide your RC vehicle with powerful cushioning, as in a conventional car. Being adjustable allows the vehicle to be driven at optimum suspension on different terrains, especially when running over bumpy or rocky ground and when turning corners.

Anodized aluminium radio tray
This is tray that houses the in-built radio receiver in your RC vehicle. Being anodized gives it increased corrosion and wear resistance, making it harder than bare aluminium.

Solid shock towers and front/rear bumper
Integrated with the suspension system, the shock towers provide a damping effect on the overall vehicle suspension.

High quality on-road tires with chrome sprayed rims
The specification for this RC electric vehicle relates to an on road racing car. The makeup of the tires is important here. It is like differentiating between a mountain bike, with its thick, knobbly, high-friction tires and a road bike, with its slimmer, low-friction tires and a less prominent tread. It all comes down to performance requirements on the terrain that the RC vehicle was designed/intended to run on. The chrome rims adds a splash of quicksilver that finishes off the wheels nicely.

7.2v 1100mAh Ni-Mh battery power (required), 7.2v 1500mah Ni-Mh battery or 7.4v 1300mah lithium battery pack (optional)
7.2-volt nickel cadmium batteries are standard power sources, often referred to as battery packs. Although they are identical in size, they differ in capacities ranging up to 3700mAh typically. As the battery pack is extra, it is advisable to go for the largest capacity that you can afford, if you desire more running time (the downside is that you’ll need more time to charge it up).

Anodized aluminium motor heat guard
Unsurprisingly, your RC electric vehicle’s motor will get very hot. The guard thankfully provides protection against heat, which results from high speed running.

High duty front bumper foam
As with conventional, real-world automobiles, the front foam bumper needs to deliver maximum protection to your RC vehicle against impacts.

Vehicle dimensions
Length, width, height, ground clearance, net weight, wheel diameter and wheel width are self-explanatory.
Your RC electric vehicle’s wheelbase will be the length from the leading edge of its front wheels to the trailing edge of its rear wheels.

Track
Track refers to track width, the distance between the center of the left tire and the center of the right tire.

Gear Ratio
This is the relationship between the numbers of teeth on two gears that are meshed or two sprockets connected with a common roller chain, or the circumferences of two pulleys connected with a drive belt.

So, there you have it. We’ve just covered some of the basic technical terms that you are likely to come across when you are enjoying your time shopping for your future RC electric vehicles. Whatever you do, don’t be fazed by these terms – think of it as an educational experience, a journey of discovery that is a part of your enjoyment of RC electric vehicles.

Electric Vehicles

Nowadays people have more varied choices in buying vehicles and cars. As now they have the option of electric vehicles. But what exactly electric vehicle is? In simple words an electric vehicle, or EV, is a vehicle with one or more electric motors for propulsion. Thus, the motion may be provided either by wheels or propellers driven by rotary motors, or in the case of tracked vehicles, by linear motors.

The energy used to propel these kind of can be obtained from various sources such as:

1. From chemical energy stored on the vehicle in on-board batteries: Battery electric vehicle

2. From both an on-board rechargeable energy storage system (RESS) and fueled propulsion power source: hybrid vehicle

3. Generated on-board using a combustion engine, as in a diesel-electric locomotive

4. Generated on-board using a fuel cell: fuel cell vehicle

5. Generated on-board using nuclear energy, on nuclear submarines and aircraft carriers

6. From more esoteric sources such as flywheels, wind and solar

7. From a direct connection to land-based generation plants, as is common in electric trains and trolley buses

Electric vehicles generally use electric motors used to drive vehicles because they can be finely controlled, they deliver power efficiently and they are mechanically very simple. Moreover these electric motors often achieve 90% conversion efficiency over the full range of speeds and power output and can be precisely controlled. Thus it won’t be wrong to say that these electric motors can provide high torque while an electric vehicle is stopped, unlike internal combustion engines, and do not need gears to match power curves.

These days electric vehicle is designed in two ways those are Battery Electric Vehicles and Hybrid vehicles. Battery Electric Vehicles covert chemical energy to electrical energy in batteries; whereas Hybrid vehicles, which convert chemical energy to electrical energy via an internal combustion engine and a generator. However, there is another less established form of electric vehicle which is the ‘plug-in hybrid’. This ‘plug-in hybrid’ attempts to combine the benefits of both these designs and allows the moderate capacity batteries of a hybrid vehicle to be recharged not only from the internal combustion engine and generator.

Electric Vehicles include electric wheelchairs, the Segway HT, electric motorcycles and scooters, motorized bicycles, golf carts and neighborhood electric vehicles. Furthermore some working electric vehicles include heavy work equipment, fork lifts, and numerous other service and support vehicles. Thus, if you are an environment conscious then electric vehicle is best for you.

Hybrid Electric Vehicle is Going to Be the New Trend of Auto Industry

Nowadays, scientists all over the world are more and more concerning the safety and environmental protection of the car. In order to achieve the sustainable development of the human society and auto industry, all the countries are trying to research different kinds of new technologies to improve the harmony between automobile and environment, especially the developed countries. It is no doubt that electric vehicle is going to be the main development direction of auto industry, which has transited from the experimental stage to test run stage. To guide the trend of world auto technology, many famous auto manufacturers are bringing out new concept vehicles which are safe, environmental protected and with high technical level.

Let us get to know about the characteristics and development of different kinds of automobiles. According to the different kinds of power supply, the automobiles can be divided into three kinds, namely, battery electric vehicle, fuel cell electric vehicle and hybrid electric vehicle.

The battery one merely relies on the battery to supply the power, however, the performance and price of the batteries can not make a breakthrough at the present time. The development of this device does not achieve the intended goal.

The fuel cell one has the advantages of high energy conversion rate, environmental protection and long service life, however, the development of this device is limited by the poor advancement of fuel cell research.

Then it comes to hybrid one which uses the electrical motor and engine to be the power unit. This kind of automobile can implement the low energy consumption, low pollution and high degree of automation through the coordination of the two inner devices. The automobile manufacturers all over the world have turned the emphasis to the development and research of hybrid electric vehicle since 1995. The enterprises in Japan, America and Germany have developed different kinds of hybrid electric vehicle includes car, minibus, truck and so on.

Take a Japan auto Company for example, which is always at the leading edge of this kind of automobile research. The level of its hybrid electric vehicle research has reached a practical level. It brought out the first mass production hybrid electric vehicle in 1997. Then, the minibus was brought out, which adopted the integrated system from the first production. To get better fuel efficiency and lower pollution, the Japan auto Company plan to apply the hybrid electric engine to the whole production in 2012. The related integrated circuit of hybrid electric vehicle is TLP869
