Walkera V120D02S Helicopter – RX2622-V Receiver – Standard & Beginner Transmitter Settings

 

RC Pro Setup Guide by: Tom Zadar

 

Setup for the Walkera V120D02S – RX2622-V Receiver – WK2801-PRO Transmitter

 

Step 1. Create a new model (or reset a current model) in the WK-2801 Pro TX. Any settings that I don’t list are default settings.

Step 2. Set to stick mode 2801 if it isn’t already set to it. Stay in 2801 stick mode.
*Make sure STICK is set to MODE2* Sometimes it will default to MODE1.

Set the throttle trim all the way down to zero. Default is center.

Step 3. Go into REVERS and set to:

1 2 3 4 5 6 7 8
N N N N N N N N

Step 4. Go into SWASH and set to 1SERVO NORM

Step 5. Go into CURVES THRCURVE and set to:

Norm 0%-25%-50%-75%-100%

ST1 & ST2 – 100%-100%-100%-100%-100%

Another option for ST1 & ST2 if 100% across is too much RPM for your motor is to use these settings.

ST-1 & ST-2 100%-90%-80%-90%-100%

I use this setup. ST-1 is a V Shaped Throttle Curve, ST-2 is 100% across.

ST-1 100%-90%-80%-90%-100%

ST-2 100%-100%-100%-100%-100%

 

Step 6. Go into CURVES PITCURVE and set to:

Norm 36.5%-41%-50%-65%-80% **

ST-1 & ST-2 20%-35%-50%-65%-80%

HOLD 20%-35%-50%-65%-80% ***

** If you are a beginner you can use Norm 50%-50%-50%-65%-80%
This will give you zero degree negative pitch for indoor flying or outdoor flying with no wind. The heli will not slam to the ground if you pull the throttle down to fast due to having negative pitch. Do not use this for stunt modes, only use this for normal mode.

***HOLD – 50-50-50-50-50 > This 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.

HOLD – 0-25-50-75-100 > If you are setting up pitch curves use this first then switch to the one above to fly.

 

Step 7. Go into GYRHLD, GYROSENS and change INH to GYRO/AUX2

Set to 0: 78%
Set to 1: 78%

Step 8. Go into GYRHLD, THROHOLD, and change INH to THRO HOLD

ACT
HOLD Pos. -15%

Step 9. Go into TRVADJ and set to:

Pitch L & H = 70%

Rudder = L120% R120%

The rest of the settings are 100%

For quicker control response increase the ALIE and ELEV Travel Adjustment. *If you set the values too high the servos might bind.
Beginners should use the default values of 100%

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

Step 10. Go into DR&EXP:

DR&EXP

Set AUTO to:

ST-1 ACT

ST-2 ACT

HOLD ACT

 

Set D/R and EXPO to your personal preference.

Standard Settings

ELEV D/R = 70% EXP +30%

AILE D/R = 70% EXP +30%

RUDD D/R = 100% EXP LIN

 

Beginner Settings

ELEV D/R = 50% EXP +30%

AILE D/R = 50% EXP +30%

RUDD D/R = 100% EXP LIN

 

Ultra Beginner Settings

These settings are for hovering and slow flight only. These settings have very low servo travel which will make the controls less responsive to stick input if you need to tame down the controls even more.
Don’t try to flip or 3D with these settings.

ELEV D/R = 30% EXP -10%

AILE D/R = 30% EXP -10%

RUDD D/R = 100% EXP +20%

 

Step 11.

Bind Radio and RX.

 

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%
