EXAMPLES OF PROGRAMMABLE MIXING
Programmable Mixing combinations are extremely versatile and can be as complex as de-
sired, limited only by the modeler's needs and imagination. A few examples of how mixing
functions can be used are shown below:
Eliminating Unwanted Control Interactions
Adverse control interactions (caused by trim,
model inaccuracies, etc.) can be compensated for
automatically, with the use of the Programmable
Mixing function.
As an example, let's presume that when top
rudder is applied during "knife-edge" flight, an
unwanted movement toward the top of the air-
craft occurs. We can use a Programmable Mixing
circuit to automaticaJly apply a small amount of
DOWN Elevator control with the application of
top (Right or Left!) Elevator.
Setting Method
1) Select the PROGRAMABLE MIX screen and
press the SET key to display the CHANNEL
SETTING screen.
2) Select RUD as the Master "mas" channel on
MX1 circuit using the or program
key.
3) Move the cursor to the "slv" position and
select ELV as the Slave channel. RUD-- ELY
will appear on the right side of the screen.
4) Return to the PROGRAMABLE MIX screen
by pressing the key.
5) Move the cursor to the "inh" position and
press the key.
6) Move the cursor to the R/U and L/D posi-
tions. The direction of Elevator movement is
set with the
and program keys, and
the rate (amount) of movement set with
5) Move the cursor to the "inh" position and
press for MX1.
6) Move the cursor to the R/U and L/D posi-
tions respectively, and set each to "—100%".
7) Move the cursor to the MX2 line with the
cursor key, and to the "inh" position
with the cursor key. Press the
ACT key to activate the MX2 circuit.
8) Move the cursor to the R/U and L/D posi-
tions respectively, and set each to +100%.
9) Direction of mixing may need to be altered,
depending on servo installation, linkage, etc.
10) Flap deflection is more conveniently set in
this case using the AFR program for CH7
(See AFR, page 17).
11) The CH7 Knob is used to control the Flap
function. Depending upon the rate set, this
can be used as a "Flap Trim" function.
12) Aileron throw is most conveniently set using
the AFR program (See AFR, page 17).
13) CH8 (AU2) can be used as a pre-set "Down
Flap" switch.
On the CHANNEL SETTING screen, move
the cursor to the MX2 "mas" position and
press the
key.
Move the cursor to the MX3 "mas" position
and set the Master channel to "AU2". Move
the cursor to the "slv" position and set the
MX3 Slave channel to AU1 and press the
key.
Return to the PROGRAMMABLE MIX
and program keys. Set the rate and
direction to give a small amount of DOWN
Elevator with the application of either direc-
tion of Rudder.
7) Move the cursor to the "sw" position and
select the desired Mixing ON/OFF Switch
option.
• Flapperons (F/apperon Mixing for
Fixed-Wing Aircraft)
CH1 and CH7 are used as the operating
channels.
Setting Method
1) Select the CHANNEL SETTING screen as
outlined earlier.
2) On MX1 set AIL as the Master channel and
AU1 (CH7) as the Slave channel.
3) On MX2 set AU1 (CH7) as the Master chan-
nel and AIL as the Slave channel.
4) Select the PROGRAMABLE MIX screen by
pressing the key.
screen by pressing the key and set the
MX3 circuit to
The direction and amount of "flap" deflec-
tion when the CH8 Switch is thrown is set
using the R/U and L/D positions on the
P.MIX screen.
14) To automatically add compensating Elevator
Trim when the "Flap" Switch is thrown,
activate the MX4 circuit and set the Master
channel to AU2 and Slave channel to ELV.
Then set the direction and amount of eleva-
tor trim (One direction will be = 0%).
The right side of the CHANNEL SETTING
screen should appear as shown.
AIL->AU1
AU1 ->AIL
AU2->AU1
AU2->ELV
15) Aileron differential can be adjusted using the
ATV proqram screen (See ATV paqe 16).
