◆Programmable Mixing 1–6
The T7AH-2400 offers six programmable mixes that allow stick or switch inputs to
control the output of two or more servos. This function allows any channel mixing
to any other channel, or to mix a channel to itself. The mix can remain ON at all
times, or it can be switched OFF when using a number of different switches in flight.
Mix values are adjustable from 0 to 125%. Each channel is identified by a four-
character name (i.e., Aileron - AILE, Elevator - ELEV, etc.). The channel appearing
first is the master channel. The second channel is the auxiliary channel. For
example,AILE - RUDD indicates aileron-to-rudder mixing. Each time the aileron
stick is moved, the rudder will automatically move in the direction and to the position
based on the value input in the programmable mix screen. Mixing is proportional,
because small inputs of the master channel will produce small outputs of the slave
channel. Each programmable mix has a mixing offset. The purpose of the mixing
offset is to redefine the neutral position of the slave channel.

10.3 Function Mode Functions
◆Dual Rate and Exponential
The Dual Rate and Exponential function allows two control rates to be programmed
and selected with a switch. Dual rates and exponentials are available on the aileron
, elevator and rudder channels. Changing the dual rate value not only affects the
maximum control authority but also affects the overall sensitivity of control. A higher
rate yields a higher overall sensitivity.
Dual rates can be controlled by their respective dual rate switches (aileron, elevator
and rudder). An auto dual rate function is available that allows to automatic
selection of the desired rates via the three-position flight-mode switch.
Exponential values are adjustable from -100% to +100%. The factory default
settings for both the 0 and 1 switch positions are 100%. Either switch position may
be selected as the low or high rate by placing the switch in the desired position and
adjusting the value accordingly.

The Exponential function allows two exponential rates to be programmed and
selected with a switch. Exponential is available on the aileron, elevator and rudder
channels. Changing the exponential value does not affect the maximum control
authority but only affects control sensitivity. Exponential is normally used to reduce
control sensitivity around neutral while still allowing high control authority at the
extremes of throw. The sensitivity around center can be tailored using the
Exponential function to precisely adjust control feel.Exponential rates can be
controlled by their respective rate switches (aileron, elevator and rudder),
or combined on a flight mode switch. Exponential is available for the aileron,
elevator and rudder channels. Expo values are adjustable from -100% (full negative
expo), LIN (linear), and +100% (full positive expo). The factory default settings for
both the 0 and 1 switch positions are LIN or 0%. Either switch position may be
selected to give any desirable EXPO rate by placing the switch in the desired
position and adjusting the value accordingly.
Note: A negative (-) Expo value will increase sensitivity around neutral, and a
positive (+) Expo value will decrease sensitivity around neutral. Normally a
positive value is used to insensitize control response around neutral.
◇To Adjust the Exponential

eliminate the cross plate interaction in extreme times.
◆Throttle Hold
The Throttle Hold function is used to practice autorotation and is often use as a
safety switch for electric helicopters, holding the throttle in the off position. When
the throttle hold switch is activated, the throttle hold function holds the throttle
servo/ ESC in a specific position (normally low or off throttle) while all other servos
function normally. The throttle hold switch is also selectable. Switch selection

◆Throttle Curve
The T7AH-2400 offers three (3) separate throttle curves with five (5) adjustable
points per curve. This function allows you to adust the throttle curve to optimize
engine rpm at a particular pitch setting. Once the throttle curves are established,
each can be activated in flight using the 3-position flight mode switch. The flight
mode switch offersthree (3) selectable curves: N=Normal, 1=Stunt 1, 2=Stunt 2.
The N, or Normal, position should be used for starting the engine and hovering.
Positions 1 and 2, or Stunt 1 and Stunt 2, should be used for aerobatic maneuvers
and forward flight.
Note: The throttle trim and hovering throttle lever are only operable when the flight
mode switch is in the Normal position. Thus, in the 1 or 2 positions, these two
functions have no effect. Each of the five (5) positions of the throttle curve are
independently adjustable from 0–100%. These five (5) positions correspond to
the position of the throttlestick.The transmitter is factory preset to the throttle
curve as indicated by the solid line in the figure below. Individual points can be
activated and increased/decreased to suit your specific needs.

◆Pitch Curve
Adjustment of the pitch curve is very similar to the throttle curve adjustment
described in the preceding section. A thorough understanding of the throttle curve
section will make pitch curve adjustment easier to understand.
The T7AH-2400 offers four (4) independent pitch curves: Normal, Stunt 1, Stunt 2
and Hold. Each pitch curve contains five (5) adjustable points — L, 1, 2, 3, and H.
Note: When setting pitch curve for throttle hold, it is necessary for the throttle hold
to be active. if this function is inhibited, the throttle hold pitch curve will not be
visible on the screen.

◆Hovering Pitch Rocker
The hovering pitch rocker operates in the same manner as the hovering throttle
rocker. It is operable while the flight mode is in the N, or Normal, position, and its
function is to shift the center point (#2) of the curve either upward or downward to
adjust pitch at the hover position.
◆Revolution Mixing (only used with non-heading hold gyros)
The Revolution Mixing Function mixes tail rotor input with the Throttle/Collective
function to counteract torque from the main rotor blades. When set up correctly,
the helicopter should climb and descend without a tendency to yaw in either
direction. Because torque reaction varies with different power settings, it is
◆Setting Up Revolution Mixing
First, adjust the helicopter so that it will hover in a neutral position with the tail rotor
trim at center. Next, establish the helicopter into a stable hover; then steadily
increase the throttle to initiate a stable climb. The body of the helicopter will move
in the opposite direction to the main rotor rotation. Increase the U, or Up, setting
until the helicopter will climb with no tendency to turn or rotate. At a safe altitude,
close the throttle and the helicopter will descend with the body turning in the same
direction as the main rotor. Increase the D, or Down, mix until the helicopter
descends with no tendency to turn or rotate. When attempting this procedure,
throttle stick movements should be slow, and the initial acceleration and
deceleration swings should be overlooked.
。

◆Manual Gyro Sensitivity Adjustment
Manual Gyro Sensitivity Adjustment allows the pilot to select from two different
gyro sensitivities during all flight conditions. This function is activated in
conjunction with the rudder dual rate switch.
◆Automatic Gyro Sensitivity Adjustment
The Automatic Gyro Sensitivity Adjustment feature allows the pilot to automatically
alter the sensitivity of the gyro from either of two pre-determined settings through
the use of the flight mode switch. As different flight modes are selected (Normal,
1, 2, Hold), the Gyro’s sensitivity rate will switch to the pre-determined com
pensation rate for each particular flight mode in use. [ PROG.MIX1 ]

◆Programmable Mixing 1–3
In helicopter mode the T7AH-2400 offers three (3) programmable mixes that allow
stick or switch inputs to control the output of two or more servos. This function
allows mixing any one channel to any other channel or the ability to mix a channel
to itself. The mix can remain ON at all times, or be switched OFF in flight using a
number of different switches. (Refer to chart below.) Mix values are adjustable
from 0 to 125%. Each channel is identified by a four-character name (i.e., Aileron -
AILE, Elevator - ELEV, etc.). The channel appearing first is the master channel.
The second channel is the slave channel. For example, AILE - ELEV would indicate
aileron-to-elevator mixing. Each time the aileron stick is moved, the elevator will
deflect, and the elevator will automatically move in the direction and to the position
based on the value input in the programmable mix screen. Mixing is proportional,
so small inputs of the master channel will produce small outputs of the slave
channel. Each programmable mix has a mixing offset. The purpose of the mixing
offset is to redefine the neutral position of the auxiliary channel.
● ON: Mixing always on ● F-NR: Flight mode normal
● F-S12: Stunt modes 1 and 2 ● F-S2: Stunt mode 2
● HOLD: Throttle hole toward self ● GEAR: Gear channel toward self
