Glossary of Terms
Ailerons:
Each side of this airplane has a hinged control sur-
face, called an aileron, located on the trailing edge of the wing.
Move the aileron stick on the transmitter left, the left aileron
moves up and the right aileron moves down. Moving the left
aileron up causes more drag and less lift causing the wing to
drop down. When the right aileron moves down, more lift is
created, causing the wing to rise. This interaction causes the
airplane turn or roll to the left. Perform the opposite actions,
and the airplane will roll to the right. This is how you control
the airplane’s direction in flight.
Carburetor:
By adjusting the needle valve in the carburetor,
you control the engine’s lean/rich fuel mixture and determine
the airplane’s speed.
Charger:
This is the device used to charge/recharge batteries.
If Ni-Cd batteries are provided with the radio, a charger is usu-
ally provided as well.
Clevis:
The Clevis connects the wire end of the pushrod to the
control horn of the control surface. A small clip, the clevis has
fine threads so that you can adjust the length of the pushrod.
Clunk:
Located in the fuel tank, a clunk is weighted and
ensures that the intake line has a steady supply of fuel.
Computer Radio:
By using advanced programming functions
of the transmitter, you can adjust the airplane without changing
any mechanical structures.
Control Horn:
This arm connects the control surface to the
clevis and pushrod.
Control Surfaces:
The moveable part of the wing and tail
that causes the aircraft to roll (aileron), pitch (elevator) or yaw
(rudder).
Dead Stick:
When the airplane is in flight gliding, without the
engine running, it is called “dead stick”.
Dihedral:
The degree of angle (V-shaped bend) at which the
wings intersect the plane is called dihedral. More dihedral gives
an airplane more aerodynamic stability. Some sailplanes and
trainer planes with large dihedral dispense with ailerons and
use only the rudder to control the roll and yaw.
Electric Starter:
This is the small motor commonly used to
start the airplane’s engine.
Elevator:
The hinged control surface functions as an elevator,
which you adjust to control the airplane’s pitch axis. Pulling the
transmitter’s control stick toward the bottom of the transmitter
adjusts the elevator upward, and the airplane begins to climb.
Push the control stick forward, and the airplane begins to dive.
Expanded Scale Voltmeter (ESV):
This device is used to
check the voltage of the battery pack.
Flight Box:
The box in which you store and transport your fly-
ing equipment is called a flight box.
Flight Pack or Airborne Pack:
These interchangeable terms
describe the radio equipment that is installed on the airplane.
Fuel Overflow Line (Vent):
This line pressures the fuel tank
and provides an even fuel flow to the engine. It also functions
as an overflow line when the fuel tank is full.
Fuel Pickup Line:
This line connects the fuel tank to the car-
buretor, usually with a clunk on the tank end to keep the fuel
flowing while the aircraft is in flight.
Fuselage:
The main body of an airplane.
Glow Plug Clip/Battery:
A 1.2-volt battery with a clip, which
is connected to your engine’s glow plug and is used to start the
engine. You remove it once the engine is running smoothly.
High Wing:
The term describes an airplane that has its wings
mounted on the top of the fuselage.
Hinge:
Moving blades on the control surface that allow you to
control the airplane’s movement. All hinges must be glued
properly and securely to prevent the airplane from crashing.
(This has already been done for you on the Easy Fly)
Horizontal Stabilizer:
The horizontal surface of the tail gives
the airplane stability while in flight.
Leading Edge:
The front of a flying surface.
Main Landing Gear:
The wheel and gear assembly the air-
plane uses to land. It is attached to the bottom of the fuselage.
Muffler:
This device muffles engine noise and increases the
backpressure from the engine’s exhaust stack, which can
improve the airplane’s performance at low speeds.
Needle Valve:
This mechanism within the carburetor adjusts
the fuel mixture and throttle. Refer to your instructions for
directions on how to adjust the needle valve.
Ni-Cd:
This abbreviation stands for Nickel Cadmium, the
chemical compound used in rechargeable batteries.
Nitro:
Short for nitromethane, a fuel additive that improves an
airplane’s high-speed performance. 10% to 15% nitro content
is recommended for
Nose Gear:
The part of the landing gear that is attached to the
nose of the fuselage. The nose gear is usually connected to the
rudder servo to help you steer the airplane on the ground.
Pitch Axis:
The horizontal plane on which the airplane’s nose
is raised or lowered. By adjusting the elevator, you can raise the
airplane’s nose above the pitch axis (climb) or lower it below
the pitch axis (dive).
