Align T-Rex 450 SA/SE Pro – Super Combo Pro DFC – Helicopter – 3D Transmitter Settings

 

RC Pro TX Setup Guide by: Tom Zadar

 

Setup for the T-Rex 450 SA/SE V2/Pro Super Combo/Pro DFC – Spektrum DX6I and DX7 Transmitter.

* 3D Settings

* T-Rex 450 Pro DFC – See the owners manual for 3GX setup.

 

Model Type: HELI

Swash Type: 3 Servo: CCPM 120 degrees

Reverse: This will vary depending on which servo brand and Tx you are using.

Revolution Mixing: Inhibit

 

GYRO: Set the gyro gain as high as it will go without getting tail wag.

I am using the Futaba GY-401 Gyro.

Rate SW-GYRO

0: 50%
1: 72.0%

 

Swash Mix:

Aileron: -60%

Elevator: +60%

Pitch: +60%

 

Travel Adjustment:

Throttle: -100% / +100%

Aileron: -100% / +100%

Elevator: -100% / +100%

Rudder: -80% / +80% – Adjust to control tail servo response and speed of pirouette.

Gear: -100% / +100% *

Pitch: -100% / +100%

* If you are using the Gear Channel to control the Gyro Gain then use these settings as a starting point and adjust them as needed. +72% / -28%

For quicker control response increase the Aileron and Elevator Travel Adjustment. *If you setthe values too high the servos might bind.

 

Pitch Curve

Normal Mode

Set pitch curve 1 for -2*
Set pitch curve 3 for 0*
Set pitch curve 5 for +11*

Curve 1 = 40% > -2* pitch measured with a pitch gauge

Curve 2 = 45%

Curve 3 = 50% > 0* pitch measured with a pitch gauge

Curve 4 = 75%

Curve 5 = 100% > +11* pitch measured with a pitch gauge

NOTE: The curve percent will vary from one helicopter to another depending on setup.
Use a pitch gauge to set the pitch for the curves.

 

Stunt Mode

Set pitch curve 1 for -11*
Set pitch curve 3 for 0*
Set pitch curve 5 for +11*

Curve 1 = 0% > -11* pitch measured with a pitch gauge

Curve 2 = 25%

Curve 3 = 50% > 0* pitch measured with a pitch gauge

Curve 4 = 75%

Curve 5 = 100% > +11* pitch measured with a pitch gauge

NOTE: The curve percent will vary from one helicopter to another depending on setup.
Use a pitch gauge to set the pitch for the curves.

Pitch Curve Hold: 0-INH-50%-INH-100%

 

Throttle Curve

Normal Mode

0-50-80-90-100

 

Stunt Mode 1

100-95-90-95-100

 

Stunt Mode 2

100-100-100-100-100

If you have the DX6I then use either the Stunt Mode 1 or Stunt Mode 2 settings of your choice.

Throttle Hold: Set to 0%

 

 

 

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-0: 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%
