STD PROGRAMMABLE MIXER – Ex: DOWN ELEV AT IDLE (continued)
A40
The Elevator should barely move downward when the
throttle is set to idle. If the Elevator moves upward,
change the +3% to a –3% to reverse the direction that
the Elevator travels. The Elevator can be made to move
more by increasing the percentage (more negative
or more positive) and move less by decreasing the
percentage. After test flying the aircraft, adjust the
percentage as may be necessary. Leave the upper value
of the selected position at 0% because there is to be
no Elevator input above idle.
7. Offset. Highlight and select OFFSET and set the
value to -140 to -160. This represents a throttle stick
position that is about 2–3 clicks up from full low
stick. This is also the point where the mixer causes
the Elevator to deflect the +3% set in the lower
position value. Above this position there is no Elevator
deflection and the Elevator returns to normal.
8. Verify Operation. Highlight and select the position
containing the +3% value using the Selector, move
the Gear switch to the ON position, and move the
throttle stick upwards from idle while observing the
position values. When the stick is brought down to
idle, the lower Pos0 value is highlighted indicating the
down Elevator deflection (+3%). Verify that the Elevator
is deflecting downward just a bit. When the stick is
advanced above idle, the upper value is highlighted
(0%) and the Elevator returns to normal (no mixing).
Now turn the Gear switch to the OFF position and
note the number next to the Program Mix Name
is now changed, indicating that the mixer is looking
at the values in the other position. Since both of the
values in this position are at 0% there is no deflection
of the Elevator – the mixer
is turned OFF regardless of throttle stick position.
Verify that the Elevator does not move when the
throttle stick is moved.
Note: To completely disable or otherwise
inhibit a mixer, highlight either the Master or
Slave and press the CLR button.
