Dihedral: The upward angle of each wing panel. Dihedral creates more stability which makes learning to fly much
easier.
Elevator: The elevator is the control surface on the back of the airplane that moves up and down. This surface controls
pitch.
Epoxy: A two-part glue containing a resin and a hardener. Epoxy is available in several drying times and is stronger than
C/A glue. Epoxy is used in high stress areas such as where wing halves are joined.
ESC: An acronym for Electronic Speed Control. See Motor Controller below.
Horizontal Stabilizer: Mounted in the rear of the airplane, the stabilizer works with the elevator to control pitch.
Motor Controller: Usually called an electronic speed control (ESC), the motor controller controls the speed of the
motor. Motor controllers can also be simple on/off switches.
Peak Charger: A type of battery charger that uses a microprocessor to sense when the flight battery is fully charged.
Once peak-charged, the charger shuts off so the battery does not overcharge.
Pushrods: They connect between the control surface and the servo, transferring the movement of the servo directly to
the control surface.
Receiver: The part of the radio system that receives the signals from the transmitter.
Rudder: The rudder is the control surface on the back of the airplane that moves right and left. This causes the nose of
the airplane to yaw right and left. Because of the dihedral in the wing, the airplane will turn right and left when the rudder
moves right and left.
Servo: The part of the radio system that produces the movement necessary to move the control surfaces. The servo
includes a small motor, gears and a circuit board.
Transmitter: The part of the radio system that you control. It transmits the control inputs to the receiver, which transfers
that information to the servos.
Vertical Stabilizer: Mounted on the back of the airplane, it works with the rudder to turn the airplane. It also gives the
airplane vertical stability.
Wing Hold-Down Dowel: A length of hardwood dowel or aluminum tube inserted through the fuselage at the front and
back of the wing saddle. It is an anchor for the rubber bands that hold the wing onto the fuselage.
Wing Saddle: The portion of the fuselage where the wing is mounted.
Z-Bend: This is a special bend made in the pushrod wire. While it cannot improve your ability to make adjustments, the
Z-Bend is the most secure way to attach the pushrod wire to the servo horn.
