3gx not powering up?

[Extensa]

Hi everyone, I have jus converted my 450 sport to a flybarless and torque tube set up but I can't get my 3gx to power up I have tested it on my 600 and it works fine I wired it up exactly the same but nothing except the rx flashes green constantly so power is getting through the 3gx to the receiver but not powering the 3gx? I have all the servos plugged into the 3gx Esc plugged into throttle I have the red orange yellow plug in first socket and green blue purple plug in second socket as it is labeled on top of 3gx , they go down to receiver red in 1 orange in 2 yellow in 3 green in 4 blue in five and purple in channel six to get the power from 3gx to rx I have the white red and black cable going from bat socket on 3gx down to bat socket on rx all wires are the right way round and fully in any ideas? Thanks, Mike.

3gx not powering up?

I know the 3gx doesn't power up if it detects a problem in the attached systems. Is the RX bound for example? I seem to recall that it doesn't light up if its not bound to your TX.

3gx not powering up?

In fact, I had the same issue. I needed to bind my AR6210 RX before the 3GX sprang into life. IIRC!

I went through the same head scratching thinking it should light up with power applied, as above once the Rx was bound the 3GX lit up.

When binding the rx to transmitter I'm getting a flashing green light not solid I have even used the power from my 600 which I know works and binding it but still can't get solid green light could it be a setting in the tx? I'm using a Futaba T8J tx and R2008SB rx thanks, Mike.

Sorry - flashing green light on what - the RX or 3GX ?

[Extensa]

Oh on the rx sorry

Hey.

Sounds like you are using a separate Spectrum receiver, if yes this is the receiver you need to bind only, you don't need to bind the 3GX at all with a separate receiver.

Once you have bound the separate receiver and it's flashing lights are now solid orange, power off the model and transmitter. Now power on the transmitter and make sure 3 servo ccpm is enabled (depending on model) then press and hold the program button on the 3GX while powering on the model. Release this button as the lights start to scroll from the left and before they reach the end. You are now in DIR mode, do your servos now move?
If notched you have wires plugged in the right way around on the receiver side and 3GX.

Ah just seen your futaba, with SBus it seems? If yes just use the single connection lead from SBus receiver the 3GX which will simplify the installation, check manual for orientation of single plug into 3GX.

I'm not too familiar with Futaba so can't remember what colour the led should be once bound. However once you have do as above and enter DIR mode. Set your transmitter to HR3 swashplate type on Futaba, not HR3.

No its a 8 channel Futaba receiver and transmitter :/

[tomatwalden]

Oh on the rx sorry

Sorry - can't really help then, as I'm a Spektrum boy! I think your problem though is with the Rx/Tx pairing - nothing to do with the 3GX. I notice Ian's spotted this thread - so you're in good hands!

[Extensa]

do you mean the white, red and black cable?

[coolice]

No its a 8 channel Futaba receiver and transmitter :/

Hey.

Yeah sorry, I did look and missed you mention Futaba.

You do have an SBus Rx so connection to the 3GX can be via a single connection only which makes things simpler.

thats ok I didn't realise it was you Ian, I got the man flu now lol. Yer its an SBus receiver, so I can get rid of the red, orange, yellow, green, blue Purple wires that connect the two? and just use the white, red and black cable to link the Rx and 3GX together?
I have tried just putting a power supple into the Rx with bind key and binding it like that but still only get flashing green light not solid?

Hey.

LOL, it's going around unfortunately.

Yes, that's it mate. You can loose the individual patch leads and just run the single white, red and black cable to link Futaba SBus receiver to the 3GX. A chap who I set up his models from him in the club use's Futaba and this is how he wires in his 3GX's, makes things much simpler.

When the binding I've just Googled this;

•Turn on the transmitter. Check the LED on the back of the transmitter to make sure that it is green. If so, proceed to step 2. If not, power down the transmitter and turn it on once again.
•Turn on the receiver.
•With the receiver on, press and hold the ID Set button (located between the two antenna exits) for more than one second. When the linking process has completed the receiver's LED will change to a solid green.

So it seems you're looking for a solid green light.
