Don't give up, its not as easy as some other hobbies to get started... its a pretty steep learning curve all round at first but 18 months in (where i am) and so, so rewarding

I'd defo get a sim of some description too... there are free ones available if cash if tight

[HeliDarren]

Wow, that would be nice I can't believe how nice the people are on this site. OK, I'll stick with it. So what setting would be OK for learning a 250? I'll dig out the manual and rebuild it from the ground up. )

Free sits? Really? Woe cool ��

is it flybarless? if so might be worth getting a cheap 3gx. lots of guides on setting that up

I'm really confused on what to do lol

Basically, your heli is flybarless. Some years back, most RC helis had a mechanical stabilisation device called a flybar. Flybars are mechanically complex however, add weight, drag and are a sod to fix after a crash. They've largely been replaced these days by electronics gyroscopes - so called flybarless controllers. The 3G and the 3GX are examples of such devices.

Darren how about I give you a 3GX unit & if you've got laptop/pc setup is relatively simple, which colour esc have you, orange or blue

I'm really confused on what to do lol

you could start by clicking Thanks on the bottom of Jims post and taking him up on his offer.

[james_2k]

+1! 3gx isnt the best or easiest to setup, but it was my first fbl and i managed it so im sure you can too! lots of info on it out there.

[HeliDarren]

My motor chugs when you give 0 to 1/4 and then spools up really quickly. Any ideas? My Th pitch is 0/80/80/80/80

[james_2k]

try a 0-100 linear curve. still does it then?pitch curve can be set to 50-50-50 so it doesnt take off

Darren take yourself over to TWo tree island at the week end, it's a club and you will find people to help you mate

Could it be the esc?

Wish I could, it's my sons 6 birthday this weekend and he's having a party ect )

its wings and wheels this weekend and I think a few of the tti guys will be there so best to pop over next weekend.some top guys there and very helpful.

Transmitter setting for my 250

Setup for the T-Rex 250 SE/Pro Super Combo/Pro DFC – Spektrum DX6I and DX7 Transmitter.

* Beginner Settings

* T-Rex 250 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 ALIE and ELEV Travel Adjustment. *If you set the values too high the servos might bind.
Beginners should use the default values of -100% / +100%



Pitch Curve – Option 1: Hover at 3/4 throttle

Spektrum DX6I: Normal Mode and Stunt Mode

Set pitch curve 1 for -2*
Set pitch curve 3 for 0*
Set pitch curve 5 for +7*

Spektrum DX7: Normal Mode, Stunt Mode 1, Stunt Mode 2

Set pitch curve 1 for -2*
Set pitch curve 3 for 0*
Set pitch curve 5 for +7*

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 = 65%

Curve 5 = 80% > +7* 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%



Option 2. If you would like to hover at mid stick to learn on use these pitch curves.
This is what I learned with. Some beginners like to learn this way instead of hovering at 3/4 throttle.
The drawback with this is you will have to learn to hover at 3/4 throttle if you plan to do any 3D flying.



Pitch Curve – Option 2: Hover at 1/2 throttle

Spektrum DX6I: Normal Mode and Stunt Mode

Set pitch curve 1 for -2*
Set pitch curve 3 for +6*
Set pitch curve 5 for +7*

Spektrum DX7: Normal Mode, Stunt Mode 1, Stunt Mode 2

Set pitch curve 1 for -2*
Set pitch curve 3 for +6*
Set pitch curve 5 for +7*

Curve 1 = 52.5% > -2* pitch measured with a pitch gauge

Curve 2 = 65%

Curve 3 = 77.5% > +6* pitch measured with a pitch gauge

Curve 4 = 80%

Curve 5 = 81.5% > +7* 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

0-50-75-75-75

Stunt Mode

75-75-75-75-75

Throttle Hold: Set to 0%



D/R & EXPO

Adjust D/R and EXPO to your personal preference.

Option 1.

Set D/R for ALIE and ELEV to 70%
Set Expo for ALIE and ELEV to + 30%

Option 2. If the settings above are not tame enough try these settings.

Set D/R for ALIE and ELEV to 50%
Set Expo for ALIE and ELEV to + 30%
Set Expo for RUDD to + 15%

All this will give you lower head speed and less servo travel so the
heli isn’t too twitchy and with the low pitch curves the heli won’t take off on
you if you move the throttle up to fast. Also the heli won’t slam down to the ground hard if you move the throttle down too fast.

When you switch between normal and stunt mode there will be no pitch jump or throttle change with these settings.
These settings have been used by us in my flying club and work well.
With the -2* pitch you will be able to pull down the heli in wind.







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%
