Chapter 3 Heli (Helicopter); Swash Type; Pitch Curve; Swashplate - Spektrum DX18 Manuel D'utilisation

CHAPTER 3 HELI (Helicopter)

NOTICE: Refer to your helicopter, gyro and governor manuals for programming recommendations.
CAUTION:
Always do a Control Test of your model with the transmitter after programming changes
to make sure your model responds as desired.

Swash Type

The Swash Type menu option assigns the swash type for your
particular helicopter model.
Select the Swash Type before completing any programming in
the Function List. The Swash Type will affect menu options in the
Function List.
Collective Type
The collective type is used to turn on "Pull" collective for
reversed collective. Available settings are Normal and Reverse.
The Collective Type allows the throttle/pitch stick to operate in
reverse and ensures trims, curves and all other functions that
are to work in reverse funtion properly.

Pitch Curve

This function supports adjustment of collective pitch in 5 fl ight
modes.
To adjust the Pitch Curve:
1. Select the Pitch Curve you wish to edit (N, 1 or 2).
2. Scroll right to select the points on the curve and edit the
respective values.
3. Press the BACK button to save the Pitch Curves and return to
the Function List.

Swashplate

The Swashplate menu option enables you to adjust the following:
• Swashplate Mix
• Exponential
• E-Ring
• Elevator Compensation
Use positive or negative Swashplate mix values as needed for
correct direction response of the helicopter.
Before making adjustments to the Swashplate mix, make sure
the throttle/collective pitch input moves the entire swashplate
up or down. If the servos are not moving in the same direction,
reverse them as necessary in the Servo Setup menu option.
When the entire swashplate moves up or down:
1. Adjust the mix value for the Aileron and Elevator channels. If
the servos do not move in the correct direction, change the
direction of the mix, for example, a positive value instead of
a negative value.
2. Adjust the mix value for the Pitch. If the swashplate does not
move in the correct direction, change the direction of the
value (negative instead of positive).
SPEKTRUM DX18 • TRANSMITTER INSTRUCTION MANUAL
Always enable Expo when using a standard rotating-arm servo.
The Expo delivers linear movement of the swashplate from a
standard rotary servo. When Expo is inhibited, the arm on a
rotary servo moves on a curved path, with decreased swashplate
movement at the extremes of the servo arm travel.
NOTICE: Do not enable Expo when using a linear servo.
Electronic E-Ring
This feature prevents overdriving servos by limiting servo travel if
the sum of your cyclic and pitch inputs exceed servo limits.
