Your 8UA system contains seven separate programmable mixers with unique mixing
capabilities. You may use mixing to correct bad tendencies of the aircraft during aerobatics,
and to make operation more pleasant. Besides mixing between arbitrary channels, the mixers
may be linked with the Advance menus in the 8UA. They can also be set to provide fixed
offsets. You may select which switch activates your mixers. The method to be used to
program mixers is given for Mixer #1, but Mixer #2-5 may be programmed in an identical
fashion. Mixer #6-7’s mixing rate can be set with a 5-point curve.
The Link function is used to ‘link’ programmable mixers with other mixing menus. For
example, you might wish to use a PMIX to provide rudder
→
aileron mixing for better knife-
edge flight in a model with flaperons using the Flaperon (FLPRON) mixing function. With
two aileron servos plugged into receiver channels CH1 and CH6, mixing only appears at the
CH1 aileron when rudder is commanded. When the Link function is turned on, this situation
is easily corrected, and mixing is applied to both CH1 and CH6.
The trim selection option allows you to choose whether the trim from the master also
affects the slave channel. The offset function lets you offset the mixing curve for the slave
channel relative to the master channel, a feature which is handy for mixing with non-centering
functions such as throttle or knobs as the master channel.
Switch selection: you may choose an ON/OFF switch for each of the programmable
mixers from the eight switches A - H. In addition, the throttle stick (CH3) may be used to
urn the programmable mixers ON and OFF.

2. Master channel setting
Select the master channel with the
(+)/(-) keys (the master is the one
that
sends
the mixing).
If you select "OFS" for the master
channel, the numerical mixing rate
setting affects the slave side only,
providing a fixed offset.
3. Slave channel setting
Select the slave channel (the one
that
receives
the mixing) with the
(+)/(-) keys.
4. Mixing rate setting
Move the master control in the
direction you want to adjust, and
one of the mixing rate displays will
flash. Set the mixing amount with
the (+)/(-) keys. Note that you can
set the mixing rate individually for
each side of the mix (left/right or
up/down).
You may reset the rate to zero by
pressing the (+)/(-) keys
simultaneously. If the amount of
mixing is set to 0%, no mixing will
occur.

1. Activate the Programmable Mixer
Press the (+) key to activate the PMIX-1 function ("ON" or
"OFF" will be displayed, depending on the ON/OFF switch's
position). Use the (-) key to INHibit the mixer.)
Default Mixing Setup
When you begin programming a
model, the mixers are set up as
follows (of course, you may change
these default settings):
PMIX-1: AIL>RUD
PMIX-2: ELE>FLP
PMIX-3: FLP>ELE
PMIX-4: THR>RUD
PMIX-5: RUD>AIL
(Mixer# 1-5 only)
PMIX-6: AIL>ELE
PMIX-7: ELE>THR
(See following page for input 5-point
curve values. (Mixer#6-7)
