EXPO Exponential Settings
EXPO Exponential Settings
The “exponentials” are in the same function as the dual rates. (Pressing the MODE key will take you to the next function
which is End Point Adjustments). The same as dual rates, “expos” can be set for both switch positions. Negative exponential
(-) decreases initial servo movement. Positive exponential (+) increases initial servo movement. The exponential “curve” may
be set anywhere between -100% and +100%.
To set the exponentials:
To set the exponentials:
1. Enter the programming mode. Access the
“
D/R
D/R“
screen with the MODE key.
2. Access the
“
EXPO
EXPO“
screen with the SELECT key.
3. Select the channel (1-aileron, 2-elevator, 4-rudder) you wish to set by pressing the SELECT
key. The active channel number will be displayed on the screen Note: If a “D/R“ will appear
on the screen, you have pressed the SELECT key too many times and displayed the values
for the D/R (dual rate values). Press the SELECT key to return to the exponentials.
4. Position the dual rate switch where desired for the value you wish to change.
5. Enter the amount of exponential with the DATA INPUT lever. (As stated above, an exponential value with a “-” in front of it
makes the initial servo movement less, or “softer.”)
6. Flip the switch to the other position to enter the exponential value for that switch position.
7. Repeat for the settings on the other channel.
EPA End Point Adjustment
EPA End Point Adjustment
Note:
Note:
Since changing the “end points” will also change the dual rates, the end points should be set prior to setting the dual
rates. If you set the dual rates first, and then go back and change the end points, the dual rate throws will also change.
The EPA function is designed to “fine tune” the servo throws in cases where changing the pushrod hookup will not achieve the
correct throw. The pushrods should first be connected to the servo arms and control horns so the correct, or near correct control
surface throw will be achieved. THEN the EPAs may be used to make small changes in the servo throw until the desired control
throw is achieved. The control throws should be set up so that the “end points” are as near to 100% as possible. If the EPA values
must be set below 70% or above 120% to get the desired throw, you should strongly consider changing the pushrod connections
so the values can be set closer to 100%. (When the EPA is set to 100% the maximum servo throw for channels 1, 2, 3 & 4 is
approximately 40 ˚ and approximately 55 ˚ for channels 5 & 6.)
To set the end points:
To set the end points:
1. Enter the programming mode and use the MODE key to access the
“
EPA
EPA”
screen. The
channel number being adjusted will the left side on the screen and the % symbol will be
flashing.
2. To change the RIGHT aileron throw move the aileron stick to the right, then push the DATA
INPUT lever up or down to change the value and the throw.
3. Move the stick to the left and use the DATA INPUT lever to change the LEFT aileron throw.
4. Use the SELECT key to display the other channels and set the other end points. Notice that
moving the stick (or switch or dial) from one end to the other changes the value displayed and
the position of the arrow for that “end” of the control input.
