DELAY
: (
HELI
) slows the servo’s reaction time when changing from one condition to another. Eases any “jumps” in transition 
from one pitch setting to another, etc. Also see

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: transmitter’s rotary control and button used in various ways during programming. ..................................................  11
Dial mix: mix that uses a knob or slider as the master control, moving the slave servo based upon the movement of the 
knob or slider. See Prog. mix.
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 Twin aileron servos.

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 Battery care and charging.
DP16K: see CAMPac.
DSC
: direct servo control. Programming and cable combination which allows operation of all receiver channels and 
functions without the transmitter transmitting. Plugs into trainer port of transmitter and special plug on receiver. Leave 
power off for both transmitter and receiver.
