Thanks Nige69. I just tried using the Rate setting and it does work like Dual
Rate on an FS-GT3b. Never would have figured that out reading the FlySky
or the Absima manuals.

The most detailed explanation is on the Help screens for Steering Exponential
- those instructions also apply to the Throttle Exponential settings
- but the Throttle Exponential Help screens do not include the detailed explanation. Hmmm..

So, the FS-iT4 has Dual Rate but FlySky changed the name to just "Rate".

Here is how the Help screens for Steering Exponential reads (less the graphic):

__________________________________________________ ______

STEERING EXPONENTIAL:

The steering exponential function modifies the transfer curve between the
steering wheel and channel 1.

Once activated, 2 buttons select which parameter value to modify:
Rate: adjust the slope of the curve. The smaller is the slope, the shorter
is the throw of the corresponding servo.
Exp: adjust the linearity of the curve. A value of 0 corresponds to a
perfectly linear curve. A positive value decreases the sensitivity near the
neutral position and increases it on the extreme sides. A negative value
increases the sensitivity near the neutral position and decreases it on the
extreme sides.

The vertical dotted line displays in real time the position of the steering
wheel.

The horizontal dotted line displays in real time the steering position after
the exponential function.

(HELP EXAMPLE GRAPHIC

In this example, the exponential function is activated, the selected
parameter is exponential and is set to its maximum value.

The vertical dotted line shows a steering wheel 20% under the neutral position
but the horizontal dotted line indicates that the resulting servo throw is less
than 10% showing the efficiency of the exponential function.

The activation of the steering exponential function can be assigned to a push
button.

The steering rate can be assigned to a trim switch.
The steering exponential can be assigned to a trim switch.

Good deal! Another piece of the puzzle falls right into place. Sweeeet.
