Have you thought building plastic model airplanes might be a fun hobby, but don’t know where to start learning how to do it? Maybe you have some questions about the process that you would like clarified. If either is the case, you have come to the right place. This article is devoted to modeling airplanes starting from the ground up, the perfect resource for beginners or those looking for some different techniques. While this article focuses specifically on model airplanes, most of the techniques and practices can be applied to other such kits as trains, tanks, ships and cars. Best of all, this article is easy to follow, and can provide museum-quality models if the instructions are adhered to

Once there was a young man named Ted who grew up beside a busy airport. Each day shiny airplanes flew right past Ted's front door. Year by year he became more passionate about these flying machines. Barely out of his teens, Ted gained his commercial pilot licence. He now brings his intense passion enthusiasm and design.

FOLLOWING ARE THE FUNCTIONS Of PARTS Of AIRPLANES

Folks With Respect To Essential Must Have Parts Pieces For Remote Controlled Airplanes The Below Professional, Very Sophisticated Specialist Information Is Critical And Key:- Throttle

.

Throttle assembly of a glow plug engine Throttle controls the speed of the engine and hence how fast or slow the propeller turns.

BELOW WE TALK ABOUT The DIFFERENT PARTS

On a glow plug (or petrol) rc airplane engine the throttle works the same as any internal combustion engine throttle, by changing the amount of fuel and air that enters the combustion chamber of the engine.

COMBUSTION!

The carburettor is operated by a single servo connected to the venturi of the carb, which opens and closes (thus changing the fuel/air mixture) in response to your throttle stick movements on the transmitter.

SPARKS THAT FLY!SPARKING

On an electric rc airplane the throttle is usually referred to as MOTOR POWER rather than throttle. Very basic electric rc planes (i.e. toy ones) might not have proportional control to motor power but just a simple on/off switch instead. Electric planes that do have proportional control to motor power have an electronic speed control, or ESC, that controls power to the motor in direct response to your Tx stick movements.

ESSENTIAL LANDING INFORMATION

In the air throttle/motor power not only controls the forward speed of the airplane but also, more importantly, the rate of climb and descent, because different amounts of lift are generated at different airspeeds. For example, if your landing approach path is too low you can make the airplane rise slightly without changing speed much, simply by opening the throttle instead of using up elevator.

Conversely, closing the throttle will cause the airplane to sink before the speed reduces.

Using throttle/motor power in this way is the correct way to fly your rc airplane, but many pilots use the elevator to control altitude and rates of climb and descent rather than engine speed. Elevators

.

The elevators are the hinged section of the tailplane, or horizontal stabiliser, at the very rear of the airplane and are the single most important control surface

ELEVATOR CONTROLS AND HOW THEY WORK

Elevators control the horizontal pitch attitude of the airplane, in other words whether the nose of the plane points upwards or downwards.When elevators are in the up position (upward deflection) the nose of the airplane is forced to point upwards, and with the elevators deflected downwards then the nose is forced downwards

This resulting nose up/nose down pitch attitude comes about as the upward/downward deflection of the elevators changes the amount of down force being generated by the tailplane

It's worth noting that a plane can still fly level, or even be descending, with a very nose-up attitude but a nose-down pitch attitude will almost always result in the plane entering a dive, thanks to our friend gravity

Elevators directly effect the plane's airspeed more than the need to climb or dive. Using elevators changes the airplanes pitch attitude Elevators should be used in conjunction with rudder and/or ailerons when making a turn, to maintain altitude during the turn and also to get the plane to bank during the turn

Ailerons.

AILERON AND LONGITUDINAL CONTROLS

Not all rc airplane controls include ailerons, in fact the majority of 3 channel radio control trainers use rudder instead. But where fitted, ailerons control the roll of the airplane about its longitudinal axis (imagine a straight line running through the centre of the fuselage, from nose to tail)

Ailerons work in pairs and are found on the trailing (rear) edge of the wing, and they work opposite to each other i.e. when one aileron moves up, the other one moves down and vice versa. Using ailerons changes the airplanes roll Ailerons work by changing the amount of lift generation over the wing. As an aileron moves upwards so it disrupts the smooth airflow over the wing surface and so lift is reduced slightly on that wing

Over on the other wing the aileron moves downwards and increases lift slightly. As a result, the airplane tilts and hence rolls towards the side that's experiencing less lift. When up elevator is applied at the same time as ailerons, the airplane is pulled round in to a banked turn;

the ailerons cause the plane to roll and the up elevator causes the nose to pitch round in that direction. Ailerons are used in all aerobatic maneuvers that involve a rolling motion.

RUDDER AND DIRECTIONAL CONTROLS

The rudder is the hinged section of the fin, or vertical stabiliser, at the rear of the airplane. It's used for directional control by changing the yaw of the airplane and works in the correct sense i.e. moving the rudder to the left causes the airplane to turn left and vice versa. Using rudder causes the airplane to yaw

Applying rudder makes the nose of the airplane point to the left or right, but rudder alone does not make the airplane roll like ailerons do

It's actually the dihedral, or the upward 'V' angle of the wing when viewed from the front, that makes the plane roll when rudder is applied; a plane with very little or no dihedral will have a much flatter turn when rudder is applied

This is all to do with a natural force called Dihedral Effect

Planes with ailerons require less dihedral than planes that rely solely on a rudder for turning, as the ailerons make the plane roll

Rudder is also very important on the ground, it's the one control that will keep your rc airplane tracking straight during a take off run or landing roll, if your plane isn't fitted with a steerable nose or tail wheel

Other important controls found on more complex rc airplanes include flaps and retractable landing gear, or 'retracts'. Flaps

FLAPS AND AILERONS

Flaps are located on the trailing edge of each wing, between the aileron and fuselage. They're used to generate more lift at slower flying speeds and, at greater deflection, to slow the airplane down close to landing by causing excessive drag.

UNLIKE AILERONS, flaps are connected in such a way that they both drop exactly the same amount together so as not to upset the roll attitude of the plane when they are deployed

Flaps are typically operated with a toggle switch or rotating dial on the transmitter. A dial is the better option because this allows the pilot to use as little or as much flap as he wants, according to the situation. Flaps operated by a single position (on/off) toggle switch will be all or nothing

When a lesser amount of flap is used (for example, 10° or so) it's quite common for the airplane to pitch upwards as soon as the flaps are lowered

This is a result of the extra lift being generated and the pilot needs to be aware of this happening before he activates the flaps

.

The trick here is to use elevator compensation, either manually or have it mixed in the radio so that when flaps are lowered, the elevator automatically drops slightly to help maintain the plane's path

Flaps Are Lowered For Landings Retracts

UNDERCARRIAGE, WHEELS AND RETRACTABLE GEAR

Retractable landing gear (undercarriage) is landing gear that folds away into the airplane's wings or fuselage once the plane has taken off

Retracts are often used on larger rc airplanes, particularly scale models where the real airplane has retractable undercarriage

Larger non-scale airplanes can also have retracts, particularly competition rc airplanes where it's necessary to reduce the amount of drag on the plane in the air. Obviously an airplane with no landing gear hanging below it experiences a lot less drag than one with

Retractable landing gear, or 'retracts '

Retracts can be operated mechanically by a servo, driven by compressed air or more recently electric worm-drive. The retraction of the landing gear is operated by the flicking of a single switch on the transmitter, typically either on the 5th or 6th channel

. Control surface mixing

Some rc airplanes are designed in such a way that they cannot have separate controllable surfaces. Planes with a large delta wing and no tailplane, for example, such as my Weasel shown below:

RC PLANES CHANNEL MIXING

There are other types of rc airplane control mixing too, but those listed above are by far the most common that you'll encounter. RC channel mixing

Channel mixing is another type of mixing supported by modern computer radios, whereby two separate channels can be mixed to operate together

A common example of channel mixing is an aileron and rudder mix; a small amount of rudder is automatically applied when you operate the ailerons

The purpose of this is to produce a cleaner turn and can prevent the effects of adverse yaw, a common situation whereby the tail drops during a turn due to increased drag over the higher wing. Aileron Differential is the 'mechanical' answer to this issue

Another example of a popular channel mix is to have elevator compensation with flap operation - as the flaps are lowered, the elevators automatically deflect downwards to counteract the natural tendency for a plane to pitch up as flaps are lowered (a result of extra lift being generated by the lowered flaps). Proportional RC airplane controls

PROPORTIONAL CONTROLS

You'll often see the word proportional when looking at radio control systems. By proportional control, we mean that the control surfaces respond directly to how much you move the stick of your transmitter

In other words, if you only move the stick a small amount then that channel will only respond a small amount. Moving the stick to the maximum position will move that channel to its maximum

Apart from the cheapest rc toys, all modern-day radio control systems are proportional. Non-proportional functions of an rc model or toy will be simple 'on/off' or 'left/right' functions

It's so important to have proportional control of your rc airplane, as this ensures accurate control. And bear in mind that most radio control planes will respond to the slightest control surface deflection - just a few millimeters deflection will be enough to change the plane's path through the air

UNDERSTANDING RC PLANES' CONTROLS

Understanding your rc airplane controls, or indeed the controls of any rc model, is of paramount importance if you want to enjoy your model to its fullest and get the most out of the hobby

Always take a bit of time to understand how your new rc airplane, helicopter or vehicle is operating and responding to your transmitter inputs, rather than just moving a stick and watching the model change direction. You'll be a much better rc'er for it

    How do planes fly:

    There are four forces which act on a plane and which must be considered during design:

    • lift
    • weight
    • thrust
    • drag


    During level flight, lift from the wings exactly balances the plane's weight. However, the other two forces do not balance; the thrust from the engines pushing forward always exceeds the drag (air resistance) pulling the plane back. Hence the planes moves through the air.

    Let's be clear about the difference between the engines and the wings and the different jobs they do. A plane's engines are designed to move the aircraft forward at high speed. This makes air flow rapidly over the wings, which throw the air down towards the ground, generating an upward force called lift. Lift overcomes the plane's weight and holds it in the sky.

    So the engines move a plane forward while the wings move it upward. The diagram shows how Newton's Third Law of Motion is applied to the wings and engines of an airplane
