LINEAR PROGRAMMABLE MIXES (PROG.MIX1-5):
Your 9C contains five separate linear programmable mixes (ACRO and GLID. HELI has 2). (Note that mixer #6-7’s mixing
RATEs are set with a 5-point curve. see CURVE MIXES, p. 62.)
There are a variety of reasons you might want to use these mixes. A few are listed here. All of the adjustable parameters
are listed below, but don’t let them scare you. For your first few times experimenting with mixes, just turn on the default
mixes, adjust them how you think they need to be, then use the servo screen to check and see if you were correct. As with
all functions, a sample setup follows, step by step, to assist you.
Sample reasons to use linear programmable mixes:
• To correct bad tendencies of the aircraft (such as rolling in response to rudder input).
• To operate 2 or more servos for a single axis (such as two rudder servos).
• To automatically correct for a particular action (such as lowering elevator when flaps are lowered).
• To operate a second channel in response to movement in a first channel (such as increasing the amount of smoke oil
in response to more throttle application, but only when the smoke switch is active).
• To turn off response of a primary control in certain circumstances (such as simulating one engine flaming-out on a
twin, or throttle-assisted rudder turns, also with a twin).
Adjustability:
• ACRO/GLID Defaults: The 5 programmable mixes default to the most frequently used mixes for simplicity. If you want
to use one of these mixes, simply select that mix number so that the master and slave servos are already selected for
you. (HELI mixes default to ail-to-rudd and elev-to-pitch.)
• PROG.MIX1 aileron-to-rudder for coordinated turns
• PROG.MIX2 elevator-to-flap for tighter loops
• PROG.MIX3 flap-to-elevator to compensate pitching with flaps
• PROG.MIX4 throttle-to-rudder ground handling compensation
• PROG.MIX5 rudder-to-aileron roll coupling compensation
• Channels available to mix: All five mixes may use any combination of CH1-8. (CH9 is not proportional and cannot be
mixed.) Offset and dials may also be set to the master channels. (see below.)
• Master: the controlling channel. The channel whose movement is followed by the slave channel.
• Another channel: Most mixes follow a control channel. (Ex: rudder-to-ailerons, 25%, no switch, corrects roll coupling.)

• Offset as master: To create an OFFSET mix, set the master as OFST. (Ex: move flaperons as flaps 20% of their total
throw when SWITCH C is in down position.)
