Swashplate Timing Mixes Example: Elevator-to-Aileron (Corrects Vertical Tracking)
H-35
Perhaps the best way to describe a Programmable Mix is
by example. The example below demonstrates a program
mix for a heli that pulls or climbs to the left when pulling
vertical into a maneuver such as a loop or stall turn. If
a mix is set up to provide a couple of degrees of Right
aileron when up Elevator is given, the aircraft will then
climb vertically with no change in Aileron tracking.
This mix uses the Elevator as the Master and the Aileron
as the Slave. The mix can be turned on and off via the
Flight Mode switch, so that you can activate the mix only
in the flight modes where the trim change is noted, most
commonly forward flight modes 1–4 only.
The mix parameters will be selected and set in the
following order: Program Mix number (3-6), Master and
Slave channels, Mix Position and Flight Mode. This is
generally a good sequence to follow when setting up a
Programmable Mix. In this situation, the Offset value
would remain at 0% (1/2 Stick).
Highlight and select one of the Standard Programmable
Mixers (PROG.MIX3PROG.MIX6) to obtain the first
Programmable Mix display. Then press ACT next to
CLR or highlight and select INH to obtain the main mix
display. The example is using PROG.MIX3.
1. Select Master. All Programmable Mixers default
to Throttle as both the Master and the Slave
(THROTHRO). The first THRO is the Master and
the second THRO represents the Slave. Since the
Elevator is to be the Master in this example, highlight
the first channel with the Selector and select ELEV to
the left of the arrow.
2. Select Slave. Highlight and select THRO to the right of
the arrow to obtain a list of channels that can be used
as the Slave. Highlight and select AILE as the Slave.
3. Select Position and Flight Modes. Move the Selector
to highlight each of the active flight modes (NRM,
ST1,ST2, ST3, ST4, GER, and then select the mix
position (0 or 1) to be used. Since we will set the mix
value in position 1, and flight modes where the mix
would not be required would be set to the POS 0 mix
position (will be left at 0%).
The number will change from 0 to 1 as the switch is
moved back and forth. When the number is 0, the mixer
is looking at the Pos0 values (not programmed yet) and
when it is a 1 it is looking at the Pos1 values (also not
programmed yet). For this example, we will assume that
this mix will be used in Stunt Modes 1 and 2 only.
