where the mechanics and electronics work together to produce the best performance.
‡ Differential
Uneven movement in each direction of a control surface. Usually used when discussing ailerons or when
describing an undesired unevenness in movement of other controls.
‡ Digital
Please see the digital servo web page: http://www.futabarc.com/servos/digitalservos.html

‡ Drag
The air resistance to forward motion. Drag can be increased with the use of certain types of devices installed

large amounts of drag, while modern aircraft such as military jets, have very low drag.
‡ Dual Rates
A switch that can make controls more or less sensitive. Lower rates are better for beginners, who tend to
overcontrol.
‡ Elevator
Hinged control surface located at the trailing edge of the horizontal stabilizer, which provides control of the
airplane about the pitch axis and causes the airplane to climb or dive. The correct direction of control is to
pull the transmitter elevator control stick back, toward the bottom of the transmitter, to move the elevator
upward, which causes the airplane to climb, and vice versa to dive.
‡ Elevator-to-Flap Mixing

tighter loops or turns, etc.
‡ Elevon (Air only)
Used for delta wing and tailless aircraft which have 2 servos operating 2 aileron-like control surfaces as
both elevator and aileron.
‡ Empennage
The vertical and horizontal tail surfaces of an airplane.
‡ Engine cut
Also known as throttle kill, or throttle cut. Used to safely shut engine off.
