Dual Rate is a percentage of End Point Adjustment. For example, if you set the Dual Rate 1 percentage value to 100%,
the control surfaces will travel the same amount as defined by your End Point Adjustment programming, and if you set the
Dual Rate 2 percentage value to 50%, the control surfaces will travel half that amount when Dual Rate 2 is Activated. Prior to
takeoff, check the position of the Dual Rate switch to ensure that it is in the position you want.
Dual Rate Overview
The Dual Rate function allows you to change the control authority of the control surfaces by changing the amount of servo travel.
For example, if you are flying an aerobatic helicopter that requires a lot of control throw for aerobatics, but that same amount of
control throw makes the helicopter difficult to control during normal flight, you can use the Dual Rate function to lower the control
throw for normal flight with just the flip of the Dual Rate switch. Two Dual Rate settings are available for the Elevator, Aileron, and
Rudder channels, and different Dual Rate settings can be programmed separately for each of the three Flight Modes.
Choosing the Channel
1) Press the Navigation Pad
34
to highlight the channel you would like
to make Dual Rate percentage value changes to. Choose either <EL>,
<AI>, or <RU>.
Dual Rate can be set for EL (Elevator), AI (Aileron), and RU (Rudder).
2) Press the Navigation Pad
56
to highlight D/R & EXP, then press the
ENTER key to display the D/R & EXP menu. The cursor will default to
D/R>100%.
3) Press the Navigation Pad
5
to move the cursor to F-MODE>COMMON.
4) Press the INC+/M1 or DEC-/M2 keys to choose either SEPARATE OR
COMMON.
5) If you choose SEPARATE, press the F-MODE key to choose the F-MODE number you would like to program the Dual Rate
and Exponential functions for. Choose from FN, F1 or F2.
Choosing the Flight Mode - Common or Separate, Continued....
1) From the Display screen, press the ENTER key to display the Programming Menus.
Changing the Dual Rate Percentage Values
Two different Dual Rate settings can be programmed to the Dual Rate switch. We recommend that Dual Rate 1 be set to the
maximum control surface throw you desire, then set Dual Rate 2 to a different value that is less than maximum. For example,
set the Dual Rate 1 percentage value to 100% and the Dual Rate 2 percentage value to 75%.
WARNING
Keep in mind that it's possible to set the Dual Rate percentage value higher than the End Point Adjustment
percentage value. For example, with the End Point Adjustment percentage value set to 100% and the Dual Rate percentage
value set to 150% the servo will move more than 100% when Dual Rate is turned ON. We strongly recommend that you set
the Dual Rate 1 percentage value to no more than 100%. This will prevent any chance of exceeding your End Point Adjustment
and overdriving your control linkage.
