Walkera Master CP Helicopter – 3D Transmitter Settings

 

RC Pro Setup Guide by: Tom Zadar

 

Setup for the Walkera Master CP – RX2637H-D Receiver – Devo Transmitter

 

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

 

SWASH – Servo Normal

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

REVERS – All normal

TRVAD – Pitch = H 51% L 54%

For quicker control response increase the ALIE and ELEV Travel Adjustment. *If you set the values too high the servos might bind.

Adjust RUDD Travel Adjustment to control the tail response and the speed of pirouettes.

SUBTR – ALL 0.0%

DREXP – Set D/R and EXPO to your personal needs/preference.

ELEV D/R = 100% EXP LIN
AILE D/R = 100% EXP LIN
RUDD D/R = 106% EXP -6%

THHLD – STATE – ACT
POSIT – 0.0%

Set throttle trim to center.

GYRO – MODE- AUTO

NORM – 80.0%

ST 1 – 80.0%

ST 2 – 80.0%

 

THCRV

MODE – NORM

PL = 0.0%

P1 = INH

P2 = INH

PM = 100.0%

P3 = INH

P4 = INH

PH = 100.0%

 

MODE – ST-1

Set EXP to OFF

PL = 100.0%

P1 = INH

P2 = INH

PM = 100.0%

P3 = INH

P4 = INH

PH = 100.0%

 

MODE – ST-2

Set EXP to OFF

PL = 100.0%

P1 = INH

P2 = INH

PM = 100.0%

P3 = INH

P4 = INH

PH = 100.0%

 

PTCRV

PL = -15%

P1 = INH

P2 = INH

PM = 0%

P3 = INH

P4 = INH

PH = +100%

 

MODE – ST-1

Set EXP to OFF

PL = -100%

P1 = INH

P2 = INH

PM = 0%

P3 = INH

P4 = INH

PH = +100%

 

MODE – ST-2

Set EXP to OFF

PL = -100%

P1 = INH

P2 = INH

PM = 0%

P3 = INH

P4 = INH

PH = +100%

Pitch Cure – Throttle Hold

These settings will help minimize damage in a crash as the swash and blades will be at mid stick zero degrees pitch.
This will also help prevent a boom strike. The swash does not move with TH with these settings.
If you want control of the swash in TH to help you land in a crash don’t use these settings.

PL = 0%

P1 = 0%

P2 = 0%

PM = 0%

P3 = 0%

P4 = 0%

PH = 0%

If you are setting up pitch curves use these settings first then switch to the settings above for when you fly.

PL = -100%

P1 = INH

P2 = INH

PM = 0%

P3 = INH

P4 = INH

PH = +100%

Receiver Gyro Sensitivity Settings

The receiver has one or two gyro sensitivity pots depending on the model of the receiver to adjust the Elevator/Aileron sensitivity, changes the flight effect.
Adjust the pot(s) to make the helicopter more response or more stable. You want a balance of good response and stability.
If you adjust the pot(s) too high the swashplate may rock back and forth in flight.

Turning up or down the Elevator/Aileron sensitivity can make the helicopter much more responsive or much more stable.
I recommend you first try the factory settings. Most of the time the factory settings are very good.

Be careful when you turn the pot. I would use the plastic screwdriver that came with the helicopter to turn the pot.
Some of the pots will turn 360* and some have a stop on the pot to keep it from turning 360*.
Be careful not to turn it anymore once the pot stops or the stop tab will get damaged and the pot will then turn 360*.

Notes:

Nose pitches up in fast forward flight with a 3 axis or 6 axis gyro.

Receiver gyro gain is too low. Increase the Elevator/Aile gyro trim pot(s).

If the receiver gyro gain is too high the heli may bob up and down.

Receiver Settings for Helicopters and Quads.

This is a list of settings that I have seen on different receivers.
The settings available on a receiver will vary depending on which model receiver it is.

Helicopters:

AILE-G.S or ALIE GYRO – Adjusts the Aileron Gyro sensitivity, changes the flight effect.

ELE-G.S or ELEV GYRO – Adjusts the Elevator Gyro sensitivity, changes the flight effect.

RUDD GS – (Rudder Gyro sensitivity adjust knob) – Adjusts the Rudder Gyro sensitivity, changes the flight effect.

ELE/AILE G. – Adjusts the Elevator/Aileron sensitivity, changes the flight effect.

ADJ Mode Switch or ADJ – WK (Adjustment Mode setting) – Turns off the Gyros. Use when leveling the Swashplate and making adjustments.

EXT – Adjusts the Servo Travel.

SERVO EXT. – (Servo Extent knob) – Servo Extent knob is used to increase or decrease Servo Travel.

ELE/AILE EXT (Elevator/Aileron Servo Extent knob) – Adjusts the Servo Travel.

RUDD EXTENT or RUDD. EXT (Rudder Servo Extent knob) – Adjusts the Tail Servo Travel.

Pit.REV (Pitch Reverse switch) – Reverse the rotation direction of the Pitch Servo.

ON – OFF (Flight mode switch) = Set/choose helicopter flight mode.

OFF – BAL – ON (Flight mode switch) = Set/choose helicopter flight mode.

BAL DELAY (Balance Control Delay) – Adjusts the signal control speed from the ELEV/ALIE servo, changes the flight effect.

Quads:

Gyro sensitivity adjust knob – Adjusts the gyro sensitivity of the front/back/left/right/tail.

—————————————————————————————

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%
