Suitable brushless motors are installed as the most common pushers to provide better flight performance and longer flight time. Pusher-propeller planes are preferred so that the propeller is not in view of the camera. Flying wing designs are also popular for FPV, as they provide a good combination of large wing surface area, speed, maneuverability, and gliding ability. Because these restrictions prohibit flying beyond the visual range of the pilot an ability which many view as the most attractive aspect of FPV , most hobbyists that fly FPV do so outside of regular RC clubs and flying fields.
There are various ways to construct and assemble an RC aeroplane. Various kits are available, requiring different amounts of assembly, different costs and varying levels of skill and experience. Some kits can be mostly foam or plastic, or may be all balsa and ply wood.
Construction of wood kits typically consists of using formers and longerons for the fuselage and spars and ribs for the wing and tail surfaces. Many designs use solid sheets of balsa wood instead of longerons to form the fuselage sides and may also use expanded polystyrene for the wing core covered in a wood veneer , often balsa or obechi. Such designs tend to be slightly heavier but are typically easier to build.
The lightest models are suitable for indoor flight, in a windless environment. Some of these are made by bringing frames of balsa wood and carbon fiber up through water to pick up thin plastic films, similar to rainbow colored oil films.
The advent of " foamies ," or craft injection-molded from lightweight foam and sometimes reinforced with carbon fiber , have made indoor flight more readily accessible to hobbyists. EPP Expanded Polypropylene foam planes are actually even bendable and usually sustain very little or no damage in the event of an accident, even after a nose dive.
Some companies have developed similar material with different names, such as AeroCell or Elapor. Amateur hobbyists have more recently developed a range of new model designs utilizing corrugated plastic , also sold as Coroplast.
Fans of the SPAD concept tout increased durability, ease of building, and lower priced materials as opposed to balsa models, sometimes though not always at the expense of greater weight and crude appearance. Flying models have to be designed according to the same principles as full-sized aircraft, and therefore their construction can be very different from most static models.
RC planes often borrow construction techniques from vintage full-sized aircraft although they rarely use metal structures. Ready to fly RTF airplanes come pre-assembled and usually only require wing attachment or other basic assembly. Typically, everything that is needed is provided, including the transmitter, receiver and battery.
RTF airplanes can be up in the air in just a few minutes and have all but eliminated assembly time at the expense of the model's configuration options. Almost ready to fly ARF or ARTF airplanes require final assembly typically including engine and fuel tank installation or electric motor, speed controller, and battery , servo and pushrod installation, control surface attachment, landing gear attachment, and sometimes require gluing the left and right wing halves together.
The fuselage, wing halves, tail surfaces and control surfaces are already constructed. ARF airplanes typically only include the airframe and some accessories such as pushrods, fuel tank, etc. Therefore, the power system glow engine, gas engine, or electric motor and any required accessories and radio system servos, transmitter, receiver, and battery must be purchased separately.
Because they do not come with a transmitter, they must be bound to one instead. This is desirable for flyers that already own a transmitter. There are several incompatible radio standards often found with Bind-N-Fly models. A programmable transmitter which can store custom parameters for multiple models is desirable so that trim and other advanced functions do not need to be altered when switching models.
Receiver Ready Rx-R models are similar to BNF models in that they are mostly assembled but let the user add their own receiver and battery, avoiding the need to deal with transmitter incompatibilities. Plug-N-Play radio control planes are the perfect answer for aeromodellers who want to buy and fly more than one RTF RC plane, but don't want to have a separate transmitter for each one.
Wood kits come in many sizes and skill levels. The wood, typically balsa and light ply, may either be cut with a die-cut or laser. Laser cut kits have a much more precise construction and much tighter tolerances , but tend to cost more than die-cut kits. Wood kits include the raw material needed to assemble the airframe, a construction manual, and full-size plans.
Assembling a model from plans or a kit can be very labor-intensive. In order to complete the construction of a model, the builder typically spends many hours assembling the airframe, installing the engine and radio equipment, covering it, sometimes painting it, installing the control surfaces and pushrods, and adjusting the control surfaces travels. The kit does not include necessary tools, so they must be purchased separately.
Care must be taken when building models from wood kits since construction flaws may affect the model's flying characteristics or even result in structural failure. Smaller balsa kits will often come complete with the necessary parts for the primary purpose of non-flying modeling or rubber band flight. These kits will usually also come with conversion instructions to fly as glow gas powered or electric and can be flown free-flight or radio-controlled.
Converting a kit requires additional and substitution parts to get it to fly properly such as the addition of servos, hinges, speed controls, control rods and better landing gear mechanisms and wheels. Many small kits will come with a tissue paper covering that then gets covered with multiple layers of plane dope which coats and strengthens the fuselage and wings in a plastic-like covering. It has become more common to cover planes with heat-shrinking plastic films backed with heat-sensitive adhesive.
These films are generally known as 'iron-on covering' since a hand-held iron allows the film to be attached to the frame; a higher temperature then causes the film to tighten.
This plastic covering is more durable and makes for a quick repair. Other varieties of heat shrinkable coverings are also available, that have fibrous reinforcements within the plastic film, or are actual woven heat shrinkable fabrics.
It is common to leave landing gear off smaller planes roughly 36" or smaller in order to save on weight, drag and construction costs. The planes can then be launched by hand-launching, as with smaller free-flight models, and can then land in soft grass. Flute board or Coroplast can be used in place of balsa wood. Planes can be built from published plans , often supplied as full-sized drawings with included instructions.
Parts normally need to be cut out from sheet wood or foam using supplied templates. Once all of the parts have been made, the project builds up just like a wood kit. A model plane built from scratch ends up with more value because you created the project from the plans.
There is more choice of plans and materials than with kits, and the latest and more specialized designs are usually not available in kit form. The plans can be scaled to any desired size with a computer or copy machine, usually with little or no loss in aerodynamic efficiency. Hobbyists that have gained some experience in constructing and flying from kits and plans will often venture into building custom planes from scratch. This involves finding drawings of full-sized aircraft and scaling these down, or even designing the entire airframe from scratch.
It requires a solid knowledge of aerodynamics and a plane's control surfaces. Plans can be drawn up on paper or using CAD software. Several materials are commonly used for construction of the airframe of model radio-controlled aircraft. The earliest model radio-controlled aircraft were constructed of wood covered with paper. Later, plastic film such as Monokote came to be widely used as a covering material.
Wood has relatively low cost, high specific Young's modulus stiffness per unit weight , good workability and strength, and can be assembled with adhesives of various types. Light-weight strong varieties such as balsa wood are preferred; basswood , pine and spruce are also used. Carbon fiber , in rod or strip form, supplements wood in more recent models to reinforce the structure, and replaces it entirely in some cases such as high performance turbine engine powered models and helicopters.
The disadvantage of using carbon fiber is its high cost. Expanded polystyrene and extruded polystyrene foam Styrofoam came to be used more recently for the construction of the entire airframe. Depron the type of foam used for meat trays blends rigidity with flexibility, allowing aircraft to absorb the stress of flying.
Expanded polypropylene EPP is an extremely resilient variety of foam, often used in basic trainers, which take considerable abuse from beginners. Foam is used either in an injection mold to make a molded airframe or is cut out of sheet to make a built up airframe similar to some wood airframes. Airplanes of foam construction are frequently referred to as "Foamies". Twinwall extruded polypropylene sheet has been used from the mid nineties.
Commonly known as Correx in the United Kingdom, it is mentioned in the sections above. Currently the Mugi group based in West Yorkshire still promote and use this material in 2mm thickness sheet form. Very tough and lightweight it has only two disadvantages. Firstly it needs particular two-part contact glues. Secondly the material is difficult to paint due to low surface adhesion. Self-adhesive coloured tapes were the answer.
Components are often laminated, taking advantage of differing flute directions for strength and forming. Models tend to exceed mm wingspan with carbon fibre tubing used for local reinforcement. The thickness used among modellers is from 2mm to 4 mm thickness. Models made out of this material are commonly known among modellers as "Spad" types simple plastic aeroplane design. The number of channels technically, servo channels a plane has is normally determined by the number of mechanical servos that have been installed, with a few exceptions, such as the aileron servos, where two servos can operate via a single channel using a Y harness with one of the two servos rotating in the opposite direction.
On smaller models, usually one servo per control surface or set of surfaces in the case of ailerons or a split elevator surface is sufficient. Generally, for a plane to be considered fully functional, it must have four channels elevator, rudder, throttle, and ailerons. A four-channel RC system gives the aeromodeler the same basic degree of control that a full-sized aircraft's primary flight controls do:.
Three channels controlling rudder or rarely ailerons, along with the elevator and throttle are common on trainer aircraft. Four channel aircraft, as mentioned above, have controls for elevator, rudder, throttle, and ailerons.
For complex models and larger scale planes, multiple servos may be used on control surfaces. In such cases, more channels may be required to perform various functions such as deploying retractable landing gear, opening cargo doors, dropping bombs, operating remote cameras, lights, etc.
Transmitters are available with as few as 2 channels to as many as 28 channels. The right and left ailerons move in opposite directions.
However, aileron control will often use two channels to enable mixing of other functions on the transmitter. For example, when they both move downward they can be used as flaps flaperons , or when they both move upward, as spoilers spoilerons. Delta winged aircraft designs commonly lack a separate elevator, its function being mixed with the ailerons and the combined control surfaces being known as elevons.
V-tail mixing, needed for such full-scale aircraft designs as the Beechcraft Bonanza , when modeled as RC scale miniatures, is also done in a similar manner as elevons and flaperons. There can be one motor for propulsion and one for steering or twin motors with the sum controlling the speed and the difference controlling the turn yaw. The plane is flown until it runs out of fuel then lands in the fashion of a glider. Turning is generally accomplished by rolling the plane left or right and applying the correct amount of up-elevator "back pressure".
A three channel RC plane will typically have an elevator and a throttle control, and either an aileron or rudder control but not both. If the plane has ailerons, rolling the wings left or right is accomplished directly by them. If the Model Jet Planes Youtube Not Working plane has a rudder instead, it will be designed with a greater amount of Dihedral Effect , which is the tendency for the airplane to roll in response to sideslip angle created by the rudder deflection.
Dihedral Effect in model airplane design is usually increased by increasing the Dihedral Angle of the wing V-bend in the wing. The rudder will yaw the plane so that it has a left or right sideslip, dihedral effect will then cause the plane to roll in the same direction. Many trainers, electric park fliers, and gliders use this technique. A more complex four channel model can have both rudder and ailerons and is usually turned like a full-sized aircraft.
That is, the ailerons are used primarily to directly roll the wings, and the rudder is used to "coordinate" to keep the sideslip angle near-zero during the rolling motion. Sideslip otherwise builds up during an aileron-driven roll because of adverse yaw. Often, the transmitter is programmed to automatically apply rudder in proportion to aileron deflection to coordinate the roll.
When an airplane is in a small to moderate bank roll angle a small amount of 'back pressure' is required to maintain height. This is required because the lift vector, which would be pointing vertically upwards in level flight, is now angled inwards so some of the lift is turning the aircraft.
A higher overall amount of lift is required so that the vertical component remains sufficient for a level turn. Many radio-controlled aircraft, especially the toy class models, are designed to be flown with no movable control surfaces at all. Some model planes are designed this way because it is often cheaper and lighter to control the speed of a motor than it is to provide a moving control surface. Instead, "rudder" control control over sideslip angle is provided by differing thrust on two motors, one on each wing.
Total power is controlled by increasing or decreasing the power on each motor equally. Usually, the planes only have only these two control channels total throttle and differential throttle with no elevator control. Turning a model with differential thrust is equivalent to and just as effective as turning a model with rudder. Lack of elevator control is sometimes problematic if the phugoid oscillation isn't well-damped leading to unmanageable "porpoising".
See "Toy class RC" section. These ruddervators are controlled with two channels and mechanical or electronic mixing. An important part of the V-Tail configuration is the exact angle of the two surfaces relative to each other and the wing, otherwise the ratio of elevator and rudder outputs will be incorrect.
