Airplane, multicopter:
This function can be used to
switch the end point of each channel of the aileron,
elevator and rudder to the two position/third position
switch.
●The rudder angle adjustment can be set for each
direction of the switch and the left and right (up and
down) directions of each channel. Ratio (D/R): This
function can set the rudder angle of each channel such
as aileron, elevator and rudder to two-speed switch.
●The end point adjustment can be set for each
direction of the switch and the left and right (up and
down) directions of each channel. EXP: Ailerons,
elevators, throttles, rudders, etc. The stick action near
the neutral point can be set to be slower or more
sensitive, and the action curve can be set according to
the needs of the maneuver.
● When the set value is negative, the action near the
neutral position becomes slow. It becomes sensitive
when the value is set to a positive value.
● D/R can set the respective ratios, and set the
direction of the switch and the left and right (up and
down) directions of each channel. Switch selection: D/R
ratio for setting aileron, elevator, rudder and other
channels and EXP switch can be selected from switches
SA~SD.
Note: The DR mode of all channels is controlled and
switched by the same switch set.
Helicopter:
This function is used when the aileron,
elevator, and rudder channels need to be switched to
use a end point other than the initial setting in different
flight operations.
● The end point adjustment can be set separately for
each switch direction and each condition.
* Travel (EXP): The aileron, elevator, throttle, and
rudder can be set to be slow or sensitive in the vicinity of
the neutral. The action curve can be set according to the
needs of the maneuver.
● Press the "-" button, and the action near the neutral
position becomes slow. Pressing the "+" button will
become sensitive.
●EXP setting can be made separately for each gear of
the switch

Terminology explanation and usage reference:
EXP (Exponential), the exponential curve, is used to
convert the linear relationship between the stick and the
rudder amount into an exponential curve. That is to
change the rudder sensitivity of the mast to the upper
and lower 1/2 position at the midpoint and the 1/2 to the
top and bottom of the mast. The EXP function generally
needs to switch between different setting values with the
size action (D/R) switch.
1 Assuming that EXP A EXP B is set to 0%, it is
equivalent to turning off the curve. At this time, the stick
is pushed and the servo will make corresponding linear
motion.
2 Assuming that EXP A EXP B is set to -50%, push
the stick up and down, you can see that when the upper
and lower push rods are within 1/2 position, the servo

action is obviously set to 0% smaller than EXP A EXP B.
A lot, and the putter is greater than the upper and lower
1/2 position, the servo action is significantly larger than
the EXP A EXP B0%. At this time, the linear relationship
between the stick and the rudder amount has been
converted into a downward bending exponential curve
relationship.
3 Assuming that EXP A EXP B is set to 50%, push the
stick up and down, you can see that when the upper and
lower push rods are within 1/2 position, the servo action
is obviously set to 0% larger than EXP A EXP B. A lot,
and when the putter is larger than the upper and lower
1/2 position, the action of the servo gear is obviously
much smaller than 0%, and the linear relationship
between the stick and the rudder amount is converted
into an exponential curve relationship of upward
bending. However, the maximum rudder amount is the
same. The larger the parameter setting value of EXP, the
more obvious the curve changes.
How to make the Dual Rate (D/R) and EXP make
the best effect?
1 Suppose we set 2 different actions (D/R) for the
elevator. The ratio A and ratio B are both set to 100%.
This action is used for aerobatics (eg, somersault flight);
2 Both the rate A and the rate B are set to 50%, and
this action is used for normal practice flights.
3 These two modes seem to solve the control of the
size of the rudder, but ignore the determination of the
maximum rudder, will change the stick sensitivity at the
same time.
4 For example, when the D/R rate A rate B is 100%,
the servo needs to be rotated by 10 degrees, only the
1/3 position of the push rod is required, but the rudder is
required when the D/R rate A rate B is 50%. Rotating the
machine by 10 degrees requires a push rod to 2/3. The
difference in operation makes it difficult for the pilot to
adapt. Causes the same stick position to be different.
5 With the use of the EXP parameter, the problem of 4
above can be solved very well, and the two action (D/R)
values correspond to two different EXP values. For
example, the rate A and the rate B are both 100% and
the EXPA EXPB is -60%.
6 Both the rate A and the rate B are 50% and the
EXPA EXPB is 0%. In this case, the servo needs to be
rotated by 10 degrees, and the position of the push rod
in the two D/R modes is almost close. Maintaining the
consistency of the mast sensitivity of the two D/R modes
in the normal flight small amplitude (less than 1/2) rod
amount correction, without affecting the maximum rudder
amount (aerobatics, etc.), the above example is only
Explain the set value of the hypothetical use of the size
action. Actual use requires several flight adjustments to
determine the parameters to achieve the best results.
