Scaling Exponentials
This function is a special function which has two sub-functions: one is dual rate setup and the other is
exponent setup. Dual rate function is used to set different rate according to different type of aircraft. For
example: Aircraft needs larger movement when you choose 3D and it needs smaller movement when
choose 3A. In addition, smaller movement is appropriate for beginners and larger movement is appropriate
for practiced ones. All above needs to be completed by setting rate. Exponential function is used to get a
better effect for professionals. When exp is positive, the sensitivity of neutral point data's output will be
decreased and the sensitivity of two terminal points will be increased. It is opposite when Exp is negative
Exponentials function is used to adjust the rate and exponential of the airplane. Once activated, 2
buttons select which parameter value to modify. The function can be set in 5 conditions. (Condition
instruction can be acquired on manual from page1 to page 7)
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 curve of all sticks or knobs (Ail、Ele 、Thro、Rud、VrA~VrE). 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 increase 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 corve. The horizontal dotted line displays
in real time the corve position after the exponential function.
Select the stick or the Knob which need to set. After that, touch the enable button to enable this
function and then select the Rate button or the Exp. button. Use the wheel to modify the corresponding
value.
As shown in the picture 21.5, VrA is selected. The exponential function is activated. The selected
parameter is rate and is set to its maximum value. The horizontal dotted line shows the VrA 60 on the left
side. But the horizontal dotted line indicates that the resulting channel output is at the position between
20 and 40 under the middle position showing the efficiency of the exponential function.
