Data reset: erase all data in a specific model. See
RESET.
Delta peak charger: common name for a specialized charger designed and required to properly peak charge both NiMH
and NiCd batteries, actually called a Zero Delta V Peak Charger. See
Battery Care and Charging.
Dial: transmitterís rotary control and button used in various ways during programming.

Differential: uneven movement in each direction of a control surface. Usually used when discussing ailerons or when
describing an undesirable unevenness in movement of other controls. See

Diode: an electronic device which only allows current to flow one direction. Used to protect radio against power surge
and reversed polarity during charging. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .14
Discharge: to deplete the electrical energy in a battery pack, usually to its lowest safe voltage, for storage or as a part of
regular maintenance. See

Dual aileron servos: (
ACRO
) a model using 2 servos on 2 separate channels to operate ailerons. May include
flaperon action.

Dual elevator servos: (
ACRO
) a model using 2 servos on 2 separate channels to operate elevators. Includes elevon,
V-tail.
Dual rates (
D/R,EXP
): reduce/increase the servo travel by flipping a switch (or by stick position). Used to make model
more comfortable to fly in different maneuvers. 7C supports triple rates by simply assigning dual rates to 3 position
switches. Includes exponential function, see
EXP

Elevator: surface which controls the modelís rate of climb or descent. Also called cyclic pitch on helicopters.
Elevator-to-flap mix: (
ACRO
) Used to apply flaps along with elevators to increase lift, allowing modeler to fly at
slower speeds, make tighter loops or turns, etc.

Elevator-to-pitch mix: (
HELI
) used to adjust pitch to counter the loss of angle of attack when elevator input is given. Not
a preprogrammed mix. See
Programmable mix.

ELEVON
: flying wing configuration with 2 servos working together to create both aileron and elevator action.

Elevons: two surfaces, one on each wing, which work as both ailerons and elevators. See
ELEVON.

UTTON
: control button used during programming to return to previous menu or close menu altogether.
END POINT
: often abbreviated EPA. Adjusts the total travel in each direction of proportional
servos
regardless of their control
assignment. Ex: adjustment to
AIL
channel will adjust only the servo plugged into channel 1 even if being used as one of two
flaperons or elevons. Note: End point is not an absolute; mixing can still drive the servo farther than this setting. . . . . . . . . . .32
