Rudder to Throttle Mixing
The Rudder to Throttle Mixing function allows you to mix a percentage of throttle control with rudder control. The Rudder to
Throttle Mixing function is typically used to reduce the tendency of the helicopter to slightly rise and fall as you pirouette. For
example, when you command a pirouette to the left, the helicopter will rise slightly and will require you to reduce throttle, and
when you command a pirouette to the right, the helicopter will fall slightly and will require you to increase throttle. With the Rudder
to Throttle Mixing function Active, the throttle will increase and decrease the desired amount when you apply left or right rudder.
The amount and the direction that the throttle increases or decreases when you move the rudder control stick is adjusted by
changing the Rudder 4 Throttle Rate percentage value either positive or negative.
IMPORTANT The Rudder to Throttle Mixing function must be assigned to a Switch Position Number before it can be
Activated. For more information, see page 45.
1) Press the Navigation Pad 56 to highlight MIXING, then press the ENTER key to display the MIXING menu. The REVO-MIX
sub-menu will be highlighted by default.
2) Press the Navigation Pad 6 to highlight RU 4 TH, then press the
ENTER key to display the RU 4 TH menu. The cursor will default to
COMMON>COM.
3) Press the YES/+ or NO/- keys to choose the desired COM or SEP
option as described previously.
Changing the Point and Rate Percentage Values
Programming the Point and Rate percentage values on a Curve allows you to achieve maximum flexibility and fine-tuning for
specific uses. The Point and Rate percentage values work together to determine the amount of throttle travel in relation to rudder
travel. Nine different Points with varying Rates can be programmed onto the Curve. Use the Input and Output display, along with
the graph, to help with programming visualization. The Point that is currently selected will blink.
1) Press the Navigation Pad 6 to highlight POINT>5.
2) Press the YES/+ or NO/- keys to choose which Point you would like to
set a Rate percentage value for.
POINT setting range is 1 through 9. Point 1 is at the low end of the Curve
and Point 9 is at the high end of the Curve. Point 5 is a the center of the
Curve. The default Point is Point 5.
3) Press the Navigation Pad 6 to highlight RATE>0%.
4) Press the YES/+ or NO/- keys to set the desired Rate percentage value.
When you program the mix Curve so that the line is straight, this
results in a Linear Curve. For example, if you set the Point 1
percentage value to -50% and the Point 9 percentage value to 50%, the
throttle will move half the amount that the rudder moves in both directions
at any given rudder control stick position.
When you change the Rate percentage value for Points 2, 3, 4, 6, 7, and 8, INH will be displayed. When you press the
YES/+ or NO/- keys, INH will change to 0%.
RATE setting range is -150% to 150%. POINT 1, 5, and 9 default Rate percentage values are 0%. The direction of throttle
travel in relation to rudder travel can be changed by programming positive or negative Rate percentage values.
As you change the Point and Rate percentage values, you can use the graph and I/O numbers to visualize the ratio
between rudder control stick movement and throttle travel throughout the entire deflection range.
