P MIX (Programmable Mix)
Set up a throttle-to-rudder mix
When you apply throttle to a powerful motor, the resultant
torque from the spinning propeller often tends to make the
plane yaw to one side (usually to the left).
This not only interferes with precision aerobatic maneuvers,
but it makes it difficult to keep the model aligned with the
runway during a full-power takeoff. To reduce the "pilot load"
of having to correct the yaw with your left thumb on the rudder
stick, you can use the P-Mix program function to automatically
mix a proportional amount of rudder with an increase of throttle.
Now let's set it up:
1) Enter the Main Function menu and scroll down to the P MIX
screen with the EDIT buttons. Activate the function by pressing
both DATA buttons-"Inh" will turn off and the default screen
shows "CH" with "MAS" blinking beneath. If, instead,
a percentage value is blinking use the right-hand CURSOR
button to scroll over until you get this "CH" and "MAS"
configuration. One of the servo channel numbers will also be
showing-the default is "1".
2) To make the throttle the master channel, push a DATA
button to light up "3". Now push the right-hand CURSOR once
more: "SLV" will light up with a number. Use a DATA button to
change this number to "4". Now the rudder channel is slaved
to the throttle channel.
3) Push the CURSOR button again: MAS 3 and a percentage
value will be blinking. Use the DATA buttons to set the value
of rudder travel to throttle travel-change to a negative value to
move the rudder in the opposite direction if necessary.
You won't likely need more than 15% to counteract the torque,
but only flight-testing will tell for sure.
P-Mix trim:
Set up a double-servo elevator with coordinated trim function
The Optic 6 Sport offers an unusually sophisticated nuance
with its P-MIX function: the ability to trim two servos
simultaneously. This is especially useful if you are using two
elevator servos (one to each half of the elevator). In flight,
if the elevator needs to be trimmed, you can make the
adjustment with the trim button next to the right-hand joystick
on the case instead of having to enter the model setup
programming in order to trim the servos independently.
Lets set this example up:
1) Enter the P MIX screen and select the master and slave
servos (2 and 5 on this radio for split elevators) and then select
the travel value (most likely 100% unless your servo pushrods
are not set up exactly the same way).
2) Now use the Right CURSOR button to move to the P MIX
screen where "TRM" is blinking. The default setting is
"OFF"-turn it to "ON" by pressing the CLEAR button.
3) Exit the menu and you now have a split elevator with trim
function.
