Ailerons. Each side of this airplane has a hinged control
surface, called an aileron, located on the trailing edge of the
wing. Move the left aileron up and the right aileron down, and
the airplane will turn or roll to the right. Perform the opposite
actions, and the airplane will roll to the left. 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 NiCad batteries are provided with the radio, a charger is
usually 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 the 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 on 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
flying 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
carburetor, 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 used to start the engine.
You remove it once the engine is running smoothly.
High Wing. This term describes an airplane that has its wings
mounted on the top of the fuselage.
Hinge. The hinges are the 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 2.)
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
airplane uses to land. It is attached to the bottom of the
fuselage.
Muffler. This device muffles engine noise and increases the
back pressure from the engine's exhaust stack, which can
improve the airplane's performance at low speeds. Mufflers are
usually required by R/C Clubs.
Needle Valve. This mechanism within the carburetor adjusts
the fuel mixture and throttle. Refer to your engine's
manufacturer instructions for directions on how to adjust the
needle valve.
