Rotate the roller to highlight Flap System then press.
To Select a Switch
The Flap System defaults to Inhibit. To activate the Flap System, rotate the roller
to highlight Inhibit then press to access the switch function. Rotate the roller to
the desired Flaps control switch. Press to access that screen.
Setting Flap and Elevator Positions
Rotate the roller to select desired Flap positions value then press the roller to
access that value. Now rotate to adjust the flap position value.
Note: it is
recommended that the flap switch position match the flap adjustment that
is being adjusted. This will allow you to observe the effects of the flap adjustment.
Repeat this for all desired Flap and elevator positions (Normal, mid and land).
Adjusting the Flap Speed
Rotate the roller to select Speed then press. Now rotate the roller to adjust the
flap speed. Press the roller to accept. The flap speed affects the flap and elevator
compensation. The flap and elevator will reach their flap positions at the same time.
SWAShPLATE
The Swashplate screen adjusts the amount and direction of travel for the aileron,
elevator and pitch functions when you activate CCPM mixing in Swash Type (see
pages 15-16). This screen also allows an Expo function that compensates for the
effect of the servo’s rotation at extremes of travel. An E-ring function also prevents
servo over-travel when simultaneous extreme aileron and elevator inputs are given.
Unless using a linear servo or a type of linkage that eliminates this effect, you
should turn on the Expo function when any CCPM mix is enabled. Swashplate
values increase or decrease the overall control travel of the selected channel. For
example if you increase Pitch value, the travel of all three servos that control pitch
will increase. If you increase aileron, the aileron and pitch servos will increase.
Increasing or decreasing this value affects the travel of that function and not the
individual servo.
Note: Negative and positive swashplate values are available.
To achieve the correct travel direction for Aileron, Elevator and Pitch, first use
the reversing function to set the servo direction on the aileron, elevator and pitch
channels. Do this so that when an aileron input on the transmitter’s stick tilts the
swashplate right and left, an elevator input tilts the swashplate fore and aft, and a
pitch input raises and lowers the swashplate. You synchronize the outputs with this
function. Then you can adjust swashplate values positively or negatively to achieve
the overall correct travel direction for aileron, elevator and pitch.
To Access the Swashplate Function
With the transmitter on and the main or telemetry screen displayed, press the
roller. The Function list displays.
Rotate the roller to highlight Swashplate then press to access.
To adjust a Swashplate value
Highlight the desired function (Aileron, Elevator or Pitch) then press the roller to
access.
Rotate the roller to change the Swashplate value, noting that positive and negative
values are available. Press the roller to accept.
Repeat the above process for all three cyclic inputs (aileron, elevator and pitch).
To Activate the Swashplate Expo Function
Rotate the roller to highlight EXPO then press to access. Spress the roller to
toggle between ACT and INH.
