Exponential does not change the total amount of servo travel at maximum control stick deflection. Exponential affects
the ratio between servo travel and control stick movement at less than 100% control stick deflection.
Choosing the Flight Mode
1) Press the Navigation Pad 56 to highlight EXP, then press the ENTER
key to display the EXP menu. The cursor will default to CH>EL.
2) Press the F-MODE key to choose the F-MODE number you would like to
program the Exponential function for. Choose from N, 1, 2, 3, or 4. The
F-MODE (N) display will change, indicating which Flight Mode you are
programming the Exponential function for.
Choosing the Channel
1) Press the Navigation Pad 56 to highlight CH>EL.
2) If you would like to set the Exponential for another channel, press the
YES/+ or NO/- keys to choose CH>AI or CH>RU.
Exponential can be set for EL (Elevator), AI (Aileron), and RU (Rudder).
Changing the Exponential Percentage Values
The Exponential function is linked directly to your Dual Rate switches. This allows you to program Exponential for each of the
three Dual Rate positions separately. For example, with the Dual Rate switch in position 1 (maximum travel), you can set 30%
Exponential, with the Dual Rate switch in position 2, you can set 10% Exponential, and with the Dual Rate switch in position 3,
you can set 0% Exponential (Linear).
WARNING If you have not used Exponential functions in the past, we suggest that you start with a small percentage
of Exponential (approximately 10%~20%) until you get used to the feel of how Exponential affects the control feel of
your model. You will find that Exponential is most useful where strong control response is desired at extreme control
stick positions, but softer control response to small control stick movements is desired in order to make very accurate
small corrections to the flight path.
1) Move the Dual Rate Switch for the channel you are setting to the
position you would like to set an Exponential percentage value for,
either 1, 2, or 3.
2) Press the Navigation Pad 6 to move the cursor to D>0% (L>0% if
setting aileron or rudder Exponential).
3) Press the YES/+ or NO/- keys to set the desired Down (or Left)
Exponential percentage value.
As you change the Exponential percentage values, you can use the graph and I/O numbers to visualize the ratio between
control stick movement and servo travel throughout the entire deflection range. Notice that as you increase Exponential,
the servo travel is decreased near the neutral position in relation to control stick movement, and as you decrease Exponential, the
servo travel is increased near the neutral position in relation to control stick movement.
4) Press the Navigation Pad 6 to move the cursor to U>0% (R>0% if setting aileron or rudder Exponential), then press the
YES/+ or NO/- keys to set the desired Up (or Right) Exponential percentage value.
EXP setting range is -100% to 100%. The default setting is 0% (Linear). Increasing the EXP percentage value softens the
control feel around neutral. Decreasing the EXP percentage value heightens the control feel around neutral.
When the Exponential value is set to 0%, the ratio between servo travel and control stick movement will be Linear. For
example, when you move the control stick 50%, the servo will travel 50%, too.
