Glossary of world aeromodelling terms

Source : aliexpress
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
