1. Introduction

So, you are interested in rc trucks (radio controlled) models of cars. Whether it is a model with an internal combustion engine (ICE) or a model with an electric motor, this article will help you determine what you prefer, to understand some general principles of model and radio control and buy everything needed for further operation.

2. Types of the car

Radio-controlled model cars can be classified as follows:
Scale (size): 1:12, 1:10, 1:8
The type of engine: internal combustion engine (or nitro) (internal combustion engine) or the Electricity (electric)
Type chassis: road racing, Formula 1, buggies, trucks, monster truck (or monsters)
Consider everything in order:
Scope
Scale model is denoted as eg 1:10 (or 1 / 10) .The most common scale - 1:10 and 1:8. Scale 1:12 is quite rare. Gaining popularity scale 1:18 (very popular among ordinary bench models of cars), there are new models as road vehicles, and monsters.
There is still scope 1:24 and 1:28, which makes a series of Mini-Z Japanese firm Kyosho, but the extent of the approximate; they indicate the average for the series.
And, finally, other extreme - the scale of 1:5 - this is a huge machine (about a meter in length) with gasoline engines.

Engine Type
Engines on the models used are as follows: The internal combustion engine (ICE, also uses the term nitro) and electric motors.
DIC (left picture) are working on a mixture of methanol, nitro methane and oil. This fuel is sold in cans in model shops. It is better to use high-quality branded fuel to the engine worked well and served for a long time. Engines are divided into classes according to their working volume:
Grade 12 (2.11 cu. Sm) - road racing model scale 1:10
15 th grade (2.5 cu. Cm) - road racing model 1:10, buggies, trucks, monsters 1:10
18 th grade (3.0 cubic cm) - buggies, trucks, monsters 1:10
21-grades (3.5 cu. Cm) - highways 1:8, buggies and monster 1:8
25 th grade (4.1 cu. Sm) - buggies and Monster 1:8

Name class went from American classification of volume in cubic inches. For example, the 15-th grade means that the engine capacity is 0.15 cu. inches. When calculated in cubic centimeters obtained: 0.15 * 2.543 = 2.458 cu. cm, ie approximately 2.5.

The higher the class ,the greater engine capacity, the higher the power. For example: the engine power of 15-th class is approximately 0.6 hp to 1.2 hp Engine 25-Class is already developing 2.5 hp and more.

Electric motors (on the right) usually operate on batteries 7.2 V or higher. Batteries are welded together from the elements by 1.2 V. Sell and individual elements for the spikes and ready-made batteries.
Electric motors are classified according to the length of wire wound inside (the number of revolutions) - 10 turns, 11 turns, 16 turns, 24 turns and so The smaller the number of turns to fast engine.

Chassis type

Chassis - the basis of the model. It fixed all the important elements - the engine, electronics, etc. Different types of gear serve different purposes and are developed based on the application.

Formula-1 - designed for the development of high speeds and racing on an absolutely flat surface. Drive - rear-wheel (2WD), although there are models with four-wheel drive (4WD).
Buggies - for racing off-road (sand, clay, gravel, dirt), can jump from a springboard. Drive - Full (4WD) or rear (2WD).
Truckee - similar in construction to the buggy, but have greater ground clearance and bigger wheels. Drive - Full (4WD) or rear (2WD).
Monsters - have huge wheels and can overcome any obstacles and ride on any surface. Large suspension travel allows you to jump from high jumps and fabricate anything. Drive - Full (4WD) or rear (2WD).
Racing models - capable of driving on a flat surface and have a high speed and good handling. Drive - Full (4WD), less rear (2WD).

3. ICE (internal combustion engine) against Electro. Comparison
Before you make a choice, you need to weigh all a and against the type of engine. Proper understanding of the strengths and weaknesses of models with an electric motor and internal combustion engines will rationally spend money and avoid problems and disappointments. So:

Models with ICE
Many models of ICE faster models with electric motor and can exceed the speed of 70-80 km / h. Be that as it may; the impact on the speed of 70 km / h in the curb or a wall could destroy the model completely, or cause costly repairs.
Engines for the car-single-cylinder two-stroke engines, which means that they need fuel (not gasoline and special fuels) .This means that you have to regularly buy fuel to the model (approximate price of 4 liters of good fuel - 45 $, though can is sufficient enough for a long time) . Plus models with engines that you can ride it as long as they wished - the main refueling tank .Typically, models with internal combustion engines are more expensive models with the electric motor (due to the higher cost of the engine).Among the major
pluses of models with internal combustion engines - a realistic sound.

Models with electric
The main disadvantage of analogue computers - quickly sits battery. You are unlikely to ride continuously for more than 15 minutes on one charge. But except for a small-time ride and slightly lower maximum speed throughout the rest of the model with the electric motor are better. The main advantage of models with
the electric motor is their silence, environmentally friendly and much better acceleration compared with models with internal combustion engines.

In any case, you will have to purchase some equipment to the model - the batteries and charger. Rechargeable batteries cost between $ 15 and vary thecapacity and impact of current. Better battery, the higher the price, and itincreases nonlinearly. Chargers are either from 12V (powered from the cigarette
lighter, or normal car battery), or from 220V (network). There are chargers that can operate on 12 and from 220V.
