Ni-Cd: Nickel Cadmium rechargeable battery. Typically used to power transmitter and receiver. See Battery care
and charging.
NiMH: Nickel Metal Hydride rechargeable battery. Newer battery technology than Ni-Cd. Longer run times but more specific
peak charging requirements. [Require a (zero) delta peak charger labeled specifically for use with NiMH batteries.]
NORMAL: trainer mode that does not give student radio the computer programming features of the master radio. See Trainer.
NT8S: standard transmitter battery pack. See Accessories.
NULL: not assigned or never changed. Ex: a mix which has a null switch assignment is always active, and can never be
changed in flight (turned off) no matter which switch is moved.
OFFSET: (HELI) separate trim settings available to each idle-up (using CONDITION) setting, or assigned to separate
switches from the condition switches. When offset is ON, movement of the trim levers adjusts the OFFSET, not the
normal condition’s trims. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .86
Offset mix: mix that independently moves the slave servo a set percentage of its total throw, not in relation to any
master. See Programmable mix.
PA2: Pilot Assist. Optional onboard device that uses optical sensors to correct model’s orientation to upright.
PARAMETER submenu: sets specific parameters. Includes reset, type, modulation, second aileron servo setup, and ATL. . . . .28
PCM: Pulse Code Modulation. An electronically encoded method of transmitting data to a receiver to help minimize the effects
of interference. (Transmission is on an FM wavelength, and uses FM crystals, module and trainer cord.). See Modulation.
Peak Charger: charger that automatically stops charging when the battery is fully charged (commonly called “peaked”).
See Battery care and charging.
Piezo gyro: gyro that uses a piezo crystal to sense angular changes. See Gyros and Governors.
Pitch-to-rudder mix: see REVO.
PITCH CURVE: (HELI) curve that sets the response of the collective pitch servo(s) to movement of the throttle/collective
S
TICK
. Independently adjustable in the normal flight mode, one for each of the 3 idle-ups, and one for throttle hold.
Adjusted to provide ideal blade response for various types of maneuvers being performed. For simplicity, the normal
condition’s curve may be set in the BASIC menu. All 5 curves are also adjustable in the ADVANCE menu. . . . . . . . . . . .84
PPM: Pulse Position Modulation. Also known as FM. Type of signal transmission. See Modulation.

Rudder-to-aileron mix: (ACRO / GLID) used to counteract undesirable roll (roll coupling) that happens with rudder input,
especially in knife-edge. Gives proper aileron input to counteract roll coupling when rudder is applied. Not a
preprogrammed mix. See Programmable mix. This is the default programming for one linear and one curve mix in
ACRO and GLID.
Rudder-to-elevator mix: used to counteract undesirable pitch (pitch coupling) with rudder input, especially in knife edge flight.
Not a preprogrammed mix. See Programmable mix. This is the default programming for one curve mix in ACRO.
