Walkera QR X400 Quadcopter – Beginner-Standard-3D Mode Transmitter Settings

 

RC Pro Setup Guide by: Tom Zadar

 

Setup for the Walkera QR X400 – RX2642H-D Receiver – Devo Transmitter

Red flashing LED on the QR X400 = Normal flight mode
Blue flashing LED on the QR X400 = 3D flight mode

QR X400 with the Walkera Camera and FPV Camera Mount which has two servos in it to tilt and rotate the camera by remote using the transmitter.

Use Airplane Mode for FPV with the FPV camera mount. Do not use Helicopter Mode. Do not 3D in Airplane Mode.

Use Helicopter Mode for Non FPV Normal flight mode and 3D flight mode.

If you are using the QR X400 without the Walkera Camera and FPV Camera Mount use Helicopter Mode for Normal flight mode and 3D flight mode.

 

 

Select a new model or reset a current model.
Any settings that are not listed below are default settings.

 

Model – Type – HELI

SWASH – 1-NRM

STMOD – MODE2 if you want the throttle on the left stick

REVERS – All normal

TRAVEL ADJ – All defaults (100%)
For quicker control response increase the ALIE and ELEV Travel Adjustment. Beginners should use the default values of 100%
Adjust RUDD Travel Adjustment to control the response of the rudder and the speed of pirouettes.

FMOD Switch – To switch between Normal flight mode and 3D flight mode when you assign these Device Output settings below.

Functions of the FMD Switch:

FMOD 0 = Normal flight mode. Red flashing LED on the QR X400.
FMOD 2 = 3D flight mode. Blue flashing LED on the QR X400.

Here is a list I made of common Dual Rate and Expo settings for Standard/Beginner/3D settings for Quads and Helicopters.

If you don’t like to use Expo you can set it to LIN.

LIN = Linear

Some radios use the term Line instead of LIN.

Spektrum – LIN

Walkera Devo – Line

Walkera 2801 Pro – LIN

 

Standard Settings

ELEV D/R = 70% to 100% > 70%, 80%, 85% are commonly used

EXP = +10% to +40% > +30% is commonly used

AILE D/R = 70% to 100% > 70%, 80%, 85% are commonly used

EXP = +10% to +40% > +30% is commonly used

RUDD D/R = 100% > For faster tail response and pirouettes (Heli) or faster rudder response and pirouettes (Quad) use 100% to 150%

EXP = LIN > For faster tail response and pirouettes (Heli) or faster rudder response and pirouettes (Quad) use -10% to -70%

 

Beginner Settings

ELEV D/R = +40% to +60% > 50% is commonly used

EXP = +30 to +40% > +30% is commonly used

AILE D/R = +40% to +60% > 50% is commonly used

EXP = +30 to +40% > +30% is commonly used

RUDD D/R = 75% to 100% > 100% is commonly used

EXP = LIN or +1% to +20% > LIN is commonly used

 

Ultra Beginner Settings

These settings are for hovering and slow flight only.

ELEV D/R = +30%

EXP = -10%

AILE D/R = +30%

EXP = -10%

RUDD D/R = 75% to 100% > 100% is commonly used

EXP = LIN or +1% to +25% > LIN is commonly used

A good combination would be to use the Beginner Settings on Switch Position “0”
and use the Ultra Beginner Settings on Switch Position “1”.

POS-0: ELEV D/R = 50% EXP +30%

POS-0: AILE D/R = 50% EXP +30%

POS-0: RUDD D/R = 100% EXP LIN

POS-1 :ELEV D/R = 30% EXP -10%

POS-1: AILE D/R = 30% EXP -10%

POS-1: RUDD D/R = 100% EXP LIN

 

3D Settings

ELEV D/R = 100% to 125% > 100% is commonly used

EXP = LIN or -10% to -70% > LIN is commonly used

AILE D/R = 100% to 125% > 100% is commonly used

EXP = LIN or -10% to -70% > LIN is commonly used

RUDD D/R = 100% > For faster tail response and pirouettes (Heli) or faster rudder response and pirouettes (Quad) use 100% to 150%

EXP = LIN > For faster tail response and pirouettes (Heli) or faster rudder response and pirouettes (Quad) use -10% to -70%
