3D

A form of flying style. With special acrobatic flying characters that are generally below the stall speed. For example torque rolls, 'walk in the park', harriers, hangers, etc.

BC / Non-Ringed

Generally this term is heard in a nitro engine, ABC stands for A = Aluminum, B = Brass, C = chrome or Composite like Nickel

This engine uses an aluminum piston and a Liner Cylinder from Chrome or composite coated brass that makes the engine more efficient for high performance. This machine does not use piston rings and pistons with very tight cylinder liners. The latest ABC machines like JBA Engine, generally hard / heavy to play

As it’s by hand. Because it is very tight it is not recommended to rotate the ass machine by hand without any fuel coming in

Adjustable Travel Volume (ATV).

ATVs are used to set the maximum travel servo on each side of the servo's neutral point. Setting ATV is useful for servo moves according to the control we want that will affect the style of flying or style.

After Run Oil

Special lubricant in design to remove residual unburned fuel. Fuel can cause corrosion or rust in some parts of the machine. By using the after run oil, the remaining fuel is removed, and the machine parts give a new protective layer. Cheap way to take care of the machine and keep the machine running long.

Ailerons

The control surfaces on the rear end of the wing are used to turn in opposite motions (one up, one down). One aileron will push the air up and one aileron will push the air down. This will make the plane turn

Or do rolling motion, so if roll right, and then right aileron will go up.

Airfoil

Wings shape when viewed from the side. Usually shaped like water drops

Amphibian

Aircraft that can carry off or landing on land and in water,

With design like hull ship, or by using float. An amphibious plane can land on the water and then pull out the wheels to rise in the air.

Angle of Attack

The angle on the wings to split the air at the time of flight, the more the angle increases the more float but will result in obstacles at the speed of the plane in accordance with the angle used.

Area

Figures, usually shown with units of square inches or feet to show the wingspan.

ARF

The term model, which shows under the model of the aircraft / helicopters is almost ready to fly, but still adds some more items to be ready to fly properly, such as engines etc.

The term ARF is now in use also on the electric plane, but in Indonesia the meaning is slightly different, where ARF electric in Indonesia means the electric aircraft is already included servo, motorcycle, esc, propeller or even battery and charger.

Axis

Imaginary lines where the body rotates to the left or right.

Backlash

One that states the condition of the wheel of the plane, too loose to slip or too tight, and the result that it produces

Ball Link

The connector uses a sphere and a circular link that sills the ball, used to connect the servo to the controller of the driving surface such as rudder etc.

Base Load Antenna

Short antenna on the model, which is used to replace the long antenna model

Battery Eliminator Circuitry (BEC)

An electronic circuit used to lower the voltage (volt) to achieve the voltage required by the receiver. BEC is commonly used in electric RC, but is also now used on engine-powered RCs when using lithium batteries

BB

This abbreviation shows the stance BALL BEARING on crankshaft RC machine. Ball bearings will make the machine more smooth and durable.

Binding

Something that happens when the servo works exceeds the strength of the circle or the circle is too long or short.

Blade Balancer

Also called "'prop balancer" on the plane. Used to see the balance of propeller or blade from side to side to eliminate vibration.

Blade Strike

A condition where propeller / blade hit another object. It looks like minimal damage, but the blade or propeller should be checked carefully and note the quality of its strength for flight safety, if unsure, better replaced.

Boring Holes in the Sky

Fly Fun on r / c plane regardless of pattern or flight path.

Buddy Box

2 the same transmitter is connected by a cable (trainer cord). This is very useful for learning to fly, or just the same plane has dual control. Instructor can immediately take control of the aircraft / heli with "trainer switch" on the transmitter.

CA (Abbreviation for "Cyanoacrylate")

Instant glue with some vikositas, (thin, medium, think and gel). This type of glue is suitable for balsa aircraft and other materials. CA has a stronger strength than Super Glue. But do not use on plane with foam material

RC Aeromodelling For Beginner

Here are tips for those of you pilot a beginner or you who are want to start the hobby RC aeromodelling please read the tips and hopefully can help you.

Aircraft type

Start with an inexpensive foam plane with a wingspan of about 60cm-100cm with a motor model of the pusher above the fuselage and wings are position the top (glider). Wing aircraft fuselage above position will be more easily controlled than the air under the wing or the middle (because it does not choose the best acrobatic wing above). Air that is too small is not good to be the best to learn as easily shifted by the wind but the planes are too big is not good because of the momentum generated when it crashed could result in considerable damage and the plane with the motor in front is vulnerable to damage the motor or shaft, remember you learn ... the best you can be sure will fall.

Channel

Start with 3-channel, aileron usage can sometimes be confusing for beginners due to its role as well as the combination with elevators. You can start with the aircraft as windragon which provides functions 3 and 4 channels. (3 air channel spin direction by relying rudder). But if you are good enough to use 4 channels in the simulator, you can skip this step.

Transmitter

Avoid using digital transmitter that is too complicated as Turnig 9X or Fly sky 9x, this is not for beginners. Transmitter for beginners is a transmitter that can be used directly without a lot of settings. Remember that you learn how to fly aided transmitter rather than vice versa, over time you will increasingly understand the need for a transmitter in accordance with the character of your fly.

There are four modes transmitter but only two are popular namely Mode 1 and Mode 2, mode 2 is usually the user with normal hand (dominant right) and throttle located on the left, while mode 1 is usually the left-handed (left dominant) and the throttle located on the right. To better understand refer to the illustration.

There are two ways to use the transmitter sticks:

The first two fingers (thumb and forefinger) position sticks two fingers clamped it.

Both with just the thumb stick position under the palm of your thumb.

I myself personally more comfortable with the first due to a faster drive and finger stick transmitter also not shifted from the sticks, while the thumb apart easily shift is also somewhat difficult to point backwards, but this is the choice of your habits so please try both.

Altitude (Very Important)

Pilot beginners usually afraid to fly high, and they will fly low, this is a mistake that is very fatal, yes I say so because ideally to learn it to be a high-flying, ideally try to fly higher with a minimum height of about 100mtr, later this will facilitate you learn orientation toward the plane, and when you lose control over the direction of a plane or make a mistake then you still have time to correct, if you compare to fly low.

As much as possible surrounding the air directing you or spinning away in front of you, avoid flying across your most novice pilot will maneuver the wrong direction when interfaced with the aircraft.

Speed

Aircraft fast indeed very pleasant but it also required quick reflexes, need to learn before you master this reflex, try to fly at low speed, not too low because the aircraft would be vulnerable stall (losing altitude), later on, the longer you will be proficient in reflex aircraft movements. ups ... so want to try his cobra movement Shukoi. :)

Electronic

Before you fly the plane RC recognize and learn the functions on the plane including the electronic pilot beginners usually cannot wait to fly, but first try to do a last check before flying like functions aileron, rudder, elevators, motors and also the battery's capacity aircraft and transmitter.

Time

Flying time depends on your habits, but an enjoyable time is early morning and late afternoon, when the sun is not too glaring but still do not forget to wear sunglasses and a hat, and stay focused on your aircraft during flight.

Field

And no less important than all this is the location you fly, avoid flying close to tall buildings, tower / power cables, this is very dangerous. Try to get a region that has a low view is quite far (author screwy ... the hell of the desert). Avoid fly a plane facing directly into the sun, note the wind speed and weather conditions around the pitch, and when the wind was strong not determined to keep flying. And also a good idea to be accompanied by someone who already

Mustang P51D Warbird 2.4Ghz 4CH 29.5" WingSpan RC Airplane

History: One of the best, popular and delightful warrior flying machine of WWII, the P-51 was intended to satisfy a British prerequisite dated April 1940. Due to the quickly mounting billows of war in Europe, the UK requested that North American Aircraft outline and fabricate another warrior in just 120 days. The NA-73X model was delivered in record time, however did not fly until 26 October 1940. The main RAF generation models, assigned Mustang Mk Is, experienced thorough testing and assessment, and it was found that the 1,100-hp Allison motor was appropriate for low-elevation strategic surveillance, yet the motor's energy diminished drastically over a height of 12,000 feet, settling on it a poor decision for aerial battle or block attempt parts. As a result of this, the RAF left its eight automatic rifles in place, additionally fitted the Mustang with cameras. In this arrangement, it served in no less than 23 RAF squadrons, starting in April 1942.

Specification :

• Ready To Fly (RTF), Complete Full 4 Channel (Elevator，Rudder, Throttle, Aileron), Electric Power (EP) Airplane Kit
• 2.4Ghz spread spectrum technology: better anti-interference ability, faster reaction speed, least power consumption

Radio control scale aircraft modeling

Perhaps the most realistic form of aeromodeling, in its main purpose to replicate full-scale aircraft designs from aviation history, for testing of future aviation designs, or even to realize never-built "proposed" aircraft, is that of radio control scale aeromodeling. RC Scale model aircraft can be of any type of steerable airship lighter-than-air (LTA) aviation craft, or more normally, of the heavier-than-air fixed wing glider/sailplane, fixed-wing single or multi-engine aircraft, or rotary-wing aircraft such as autogyros or helicopters.

Full-scale aircraft designs from every era of aviation, from the "Pioneer Era" up to World War I's start, through to the modern day in the 21st century, have been modeled as radio control scale model aircraft. Builders of RC Scale aircraft can enjoy the challenge of creating a controllable, miniature aircraft that merely "looks" like the full scale original in the air with no "fine details", such as a detailed cockpit, or go into seriously replicating many operable features of a selected full scale aircraft design, even down to having operable cable-connected flight control surfaces, illuminated navigation lighting on the aircraft's exterior, realistically retracting landing gear, etc. if the full-sized aircraft possessed such features as part of its design.

Various scale sizes of RC scale aircraft have been built in the decades since modern digital-proportional, miniaturized RC gear came on the market in the 1960s, and everything from indoor-flyable electric powered RC Scale models, to enormous "giant scale" RC Scale models, in scale size ranges that usually run from 20% to 25%, and upwards to 30 to 50% size of some smaller full scale aircraft designs, that can amazingly replicate some of the actual flight characteristics of the full scale aircraft they are based on, have been enjoyed, and continue to be built and flown, in sanctioned competition and for personal pleasure, as part of the RC scale aeromodeling hobby.

Free flight (model aircraft)

The essence of free-flight is that the aircraft have no need for any form of external control, for instance by radio. Aircraft of this type have been flown for over two centuries. They are designed to be inherently stable in flight; if disturbed by a gust of wind or a thermal up-current they will return automatically to stable flight. For this reason most free flight aircraft are not replicas of man-carrying ones, for they are designed for a quite different purpose. Their stability is achieved by a combination of design and trim, - the relationship between centre of gravity, wing and tailplane incidence and rudder setting.

Because they are much lighter with respect to their wing area, free-flight aircraft fly much slower than the engine-powered radio-controlled models that many people first think of when ‘model aircraft’ is mentioned. Most of them glide at little more than walking pace and few weigh more than 500 grams.

Usually the sole object in free-flight is flight duration, and one of the sport’s fascinations and challenges is to design the most efficient aircraft within the various competition limits on such parameters as minimum weight, maximum wing area and motive power. It is solely a stopwatch, rather than any judge’s opinion, that decides the result.

Types of R/C helicopters

Common power sources are Nitro (nitromethane-methanol internal combustion), electric batteries, gas turbines, petrol and gasoline.

Mechanical layouts include CCPM in all power sources, fixed-pitch electric rotors and coaxial electric rotors.

Practical electric helicopters are a recent development but have rapidly developed and become more common, overtaken nitro helicopters in common use. Gas-turbine helicopters are also increasing in popularity, although the high cost puts them out of reach of most people.

Nitro

Nitro helicopters come in different sizes: 15, 30, 50, 60 and 90 size. These numbers originated from the size of nitro engine used in the different models (0.30 cu in, 0.50 cu in and so on). The bigger and more powerful the engine, the larger the main rotor blade that it can turn and hence the bigger the aircraft overall. Typical flight times for nitro helicopters is 7-14 minutes depending on the engine size and tuning.

Electric

The 233 km/h fast electric helicopter TDR

Recent advancements in battery technology are making electric flying more feasible in terms of flying time. Lithium Polymer (LiPo) batteries are able to provide the high current required for high performance aerobatics while still remaining very light. Typical flight times are 4-12 minutes depending on the flying style and battery capacity.

In the past electric helicopters were used mainly indoors due to the small size and lack of fumes. Larger electric helicopters suitable for outdoor flight and advanced aerobatics have become a reality over the last few years and have become very popular. Their quietness has made them very popular for flying sites close to residential areas and in places such as Germany where there are strict noise restrictions. Nitro helicopters have also been converted to electric power by commercial and home made kits.

The smallest remote-controlled production model helicopter made (Guinness World Records 2006) is the Picooz Extreme MX-1 sold at many toy stores (although this is infrared controlled, not radio), electronics stores and internet stores, costing about $30 (£28). The next smallest is the standard Picooz helicopter.

Several models are in contention for the title of the smallest non-production remote-controlled helicopter, including the Pixelito family of micro helicopters, the Proxflyer family, and the Micro flying robot.

A recent innovation is that of coaxial electric helicopters. The system's inherent stability has, in recent years, made it a good candidate for the design of small models for beginner and/or indoor use. Models of this type, as in the case of a full-scale helicopter, eliminate rotational torque and extremely quick control response, both of which are very pronounced in a CCPM model.

While a coaxial model is very stable and can be flown indoors even in tight quarters, such a helicopter has limited forward speed, especially outdoors. Most models are fixed-pitch, i.e. the collective pitch of the blades can not be controlled, plus the cyclic control is only applied to the lower rotor. Compensating for even the slightest breeze causes the model to climb rather than to fly forward even with full application of cyclic (nick). More advanced coaxial constructions with two swashplates and/or pitch control - common for the big coaxial helicopters like Kamovs - have been realized as models in individual projects but have not seen the mass market as of 2009.

Radio controlled helicopters

Radio-controlled helicopters (also RC helicopters) are model aircraft which are distinct from RC airplanes because of the differences in construction, aerodynamics, and flight training. Several basic designs of RC helicopters exist, of which some (such as those with collective pitch, meaning blades which rotate on their longitudinal axis to vary or reverse lift) are more maneuverable than others. The more maneuverable designs are often harder to fly, but benefit from greater aerobatic capabilities.
Flight controls allow pilots to control the collective and throttle (usually linked together), the cyclic controls (pitch and roll), and the tail rotor (yaw). Controlling these in unison enables the helicopter to perform most of the same manoeuvres as full-sized helicopters, such as hovering and backwards flight, and many that full-sized helicopters cannot.
The various helicopter controls are effected by means of small servo motors, commonly known as servos. A piezoelectric gyroscope is typically used on the tail rotor (yaw) control to counter wind- and torque-reaction-induced tail movement. This "gyro" does not itself apply a mechanical force, but electronically adjusts the control signal to the tail rotor servo.
The engines typically used to be methanol-powered two-stroke motors, but electric brushless motors combined with a high-performance lithium polymer battery are now more common, as improved performance and decreasing prices bring these within reach of more people. Gasoline and jet turbine engines are also used.

Aircraft Aeromodels

A radio-controlled aircraft (often called RC aircraft or RC plane) is a model aircraft that is controlled by remotely, typically with a hand-held transmitter and a receiver within the craft. The receiver controls the corresponding servos that move the control surfaces based on the position of joysticks on the transmitter, which in turn affect the orientation of the plane.
Flying RC aircraft as a hobby has been growing worldwide with the advent of more efficient motors (both electric and miniature internal combustion or jet engines), lighter and more powerful batteries and less expensive radio systems. A wide variety of models and styles is available.
Scientific, government and military organizations are also utilizing RC aircraft for experiments, gathering weather readings, aerodynamic modeling and testing, and even using them as drones or spy planes.
