Dual Rates / Exponential Settings
The aileron, elevator and rudder dual rates on the 6EXHP are simultaneously activated by the dual rate switch. The amount of
travel decrease for each control may be set between 0% and 100% of the values set for the end points (explained in End Point
Adjustment on page 12).
Note
: It is possible to set a dual rate value to zero, thus causing no response from that channel. If the dual rates are
inadvertently set to zero, a crash could result.
Note
: When performing initial model setup, the E.P.A.s should be set
prior to
setting the dual rates. When setting the E.P.A.s
for the first time on a new model, the dual rates should be set to 100%.
D/R Dual Rate Settings
To set the dual rates:
1. Enter the programming mode. Access the
“D/R”
screen with the MODE key.
2. Select the channel to be adjusted (1-aileron, 2-elevator, 4-rudder) by pressing the SELECT
key until the desired channel number the left side on the screen. Note: If a
“EXPO”
will
appear on the screen, you have pressed the SELECT key too many times and displayed
the values for the exponentials (explained later). Press the SELECT key to return to the dual
rate values.
3. Place the dual rate switch in the desired position for the value you wish to change. (Generally,
pilots prefer to have the switch in the “up” position for the high rate, and in the “down”
position for the low rate.)
4. Change the dual rate value using the DATA INPUT lever until the desired control throw is achieved. If you wish to change
the control throw when the switch is in the other position as well, flip the switch, then use the DATA INPUT lever to change
the throw.
5. Repeat the procedure for the other dual rate (channel 2-elevator, 4-rudder).
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:
1. Enter the programming mode. Access the
“D/R”
screen with the MODE key.
2. Access the
“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
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
