to operate the D/R and Expo function.
◆Dual Rate and Exponential
The Dual Rate and Exponential function allows two control rates to be programmed
25
and selectedwith a switch. Dual rates and expos are available on the aileron,
elevator and rudder channels. Changing the dual rate value not only affects the
maximum control authourity but also affects the overall sensitivity of control.
A higher rate yields a higher overall sensitivity. The sensitivity around center can
be tailored using the Exponential function to precisely adjust.
Dual and Expo rates can be controlled by their respective dual rate switches or by
one common switch. The choices for this are found on the D/R SWITCH SEL screen
in the System Setup Mode for Airplanes.
Dual rate values are adjustable from 0–125%. The factory default settings for both
the 0 and 1 switch positions are 100%. Exponential values are adjustable from 100% to +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.

he Dual Rate and Expo functions for aileron, elevator and rudder can be combined
on a single switch, high or low rates to be selected via one switch. The choices for
this are found on the D/R SWITCH SEL screen in the System Setup Mode for
Airplanes.(have a look at page 50.)
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
26
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 single switch.The choices for this are found
on the D/R SWITCH SEL screen in the System Setup Mode for Airplanes.
Exponential is available for the aileron, elevator and rudder channels. Expo values
are adjustable from-100% (full negative expo), straight line, and +100% (full positive
expo). The factory default settings for both the 0 and 1 switch positions are straight
line or 0%. You can select one between the witch's two position to open the desirable
EXPO rate. The position of the switch is the place of ajusting the accordingly EXPO
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 neutra
value. Press to enter

wrong channels. The right aileron should be plugged into the aileron channel,
while the left aileron should be plugged into the flap channel.
◆throttle idle
Throttle idle function used to safety close engine, for fixed wing
aircraft, it is always a very safe switch, lock throttle to the closed position. When
the throttle lock switch is activated, and all the other servos are normal, throttle
idle function lock throttle servo/ESC to specific position (normal low or close the
throttle). Throttle idle switch is also can be selected. Switch choice positions
including rudder double proportion, auxiliary 2, aileron double row or the elevator
servo's double ratio switch position
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 fourcharacter 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.

◆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.

each—one for flight mode position N, and the other for Stunt 1 and Stunt 2
positions. The U, or Up, mixing adjusts the tail rotor compensation for the mid to
high throttle/stick setting, and the D, or DOWN, mixing adjusts the tail rotor
compensation for the mid to low throttle/stick setting.In the Function Mode, use
the UP or DOWN keys to select Revolution Mixing screen.!!
◆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.

◆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

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.

◆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.
◆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

●In the withdrawn or extensions of the conditions don't let the steering gear run
overload.be sure they could be in full deflection operation.
●Ensure that all of the steering gear running freely, no connected or bound aside.
A bind of the control connection will lead the steering gear. to cost excessive
current . A stall of the steering gear can be in just a few minutes for draining batteries.
●Once be noticed in the flight, correct any control surfaces.Because this condition
could damage the Partial pressure gauge in the steering engine.Ignore the beating
buzz or beating flyingis very dangerous.
●When installing steering gear, use the rubber gaskets and provide brass servo
gasket,Don't put the steering gear installed screws too tight, because this will make
rubber gasket inhibition invalid.
●To ensure the safety of the servo arm fixed in the steering gear.
●Do not use steering gear arm when the steering gear arm turn to yellow or
decoloration .The steering gear arm is a fragile, at any time could suddenly be
rupture, and it could well lead to a plane crash.
●Often check all related install screw and link. The vibration of plane is due to
link or often too loose screw.。
◆General descriptions

or good maintenance words they can also cause the potential risk.
It is very important to fix your system right. In addition,your professional ability need
to be enough to control the plane.if you were a new hand ,please learn the
experience from the old hand , or the local shop.
◆Safety knowledge
●Be sure you battery have the right charging in the first fight.
●Tracking at any time your system is on,and then you could know how long your
65
system could last .
●Before the first flying ,check the Underside distance,please have a look at the daily
flight check chapter.
●Before flying ,check all the appearance control .
●Don't fly in the public, parking lot or other personal property losses.
●Don't fly in the bad weather.Very poor visibility can lead to problems or the plane
out ofcontrol of the direction.strong wind also can lead the same problem.
●Don't risk.when flying ,you notice the Unstable or abnormal situation.
◆Standard operation
The model is concerned with the flying model plane's security issues and good
judgment. But in view of safety, we encourage the operators of the remote control
