My new 3gx

[sycomoto]

Well it turned up today and boy is this thing tiny. I fitted it to my trex 700 and sorted all the wiring out and this is where I've gone and got myself tied in knots. Now the first question is when you've got everything plugged in to you first comedy the USB and download anything or do you run through the setup procedure first. Everything on my trex is moving the wrong way even though is using the same model memory as it was on the 3G. Is it still on a 120deg 3 servo mix in the tranny or do I have to set it at 1 servo and the gismo does the rest. Their seems some bits missed out on the manual which is confusing me a bit. If Antibes got settings for a dx8 they wouldn't mind me using I'd be grateful

Dont need the pc lead,setup is the same as the 3g just run thru the manual.

Treat it as a complete clean install with a fresh tx setup and ignore what your 3g did.

Think you will like it,getting very good feedback on other forums.

Is it on a Nitro? Are you gonna try the gov?

hi chris. thanks for that. its on mt trex 700n. i think my issue is my inability to get my head round my dx8. whatever i do just seems to do the opposite to what i want. today i set the swash on my trex using my new leveling tool and got it pretty bang on using a spektrum reciever. i then plugged in the 3gx and everythings moving the wrong way. i've tryed to change things about but it just makes matters worse. the major problem is i don't have any experts locally who use the dx8 so i'm kinda flying blind.

Not familiar with the DX8 myself im afraid

are you using a main Spektrum Rx or plugging 2 satellites direct into the unit for final use?

Align 3Gx on DX8

Guys,

Here are my settings if it helps in any way.

These are on a Vibe 50, but using Align Servos all round, so shouldn't be too far off with your 700. I would go through your set up again without the 3GX plugged in first, to get the swash moving the right direction and then plug the 3GX in, re-bind and work through the 3GX set-up.

Swash Mix
Ail +65
Ele + 65
Pitch + 65

On my T-Rex 700, both Ail & Ele are positive and Pitch is negative, so there is some difference (sorry if this confuses things even more)

Servos reversed on Ail & Elevator

Governor set at 87% in Idle up 1 and 97% in Idle up 2, this is running on a Vibe 50 though, so check your gearing and set the headspeed via the 3GX software, worked absolutely bang on for mine.

The other thing to check is the Gyro gain and Governor channels, the seetings in the software are not that clear and are different if you are using a main receiver or just satellites.

If you are using a main receiver, gyro gain lead goes to channel 5 (gear) and Governor to channel 7(aux2)

Hope this helps in some way.

Cheers

two satellites, forgot to ask, when you set up the swash in your tranny did you do 3 sevos 120deg or is the 3gx like total g and requires 1 servo setup and it sorts it out.

[gmurrell]

Set-up is done with 3 servos at 120 degrees and you can add sub trim etc to get the swash perfectly level before the 3GX setup.

[gmurrell]

If you are using two satellites, your governor and gyro gain leads will be reversed, if I remember correctly??

Here's something I'm confused by. I've set my swash level with the tool with the radio on and when I press Dir to start programming the swash drops at the back. So do you set everything in the 3GS and then go back and redo ?
It's also like the servos don't always return to the same position. I've also noted even though the servos ate all the same they don't lift the swash all at the same time the elevator seems to be just a bit behind, is this what the keen by fazing. I was trying to get the pitch and stuff sorted today but as I can't seem to get everything to run together I've ended up with more pitch to one side than the other at full aileron more forward pitch than back. Buggered of o can fathom it.
Recon I should have stuck to planks

[igottomanyhelis]

just get everything working in the right direction first,then go into dir and start swash leveling 0 deg and all that i have had problems with my 500 but found out today it was set on 700 modal been out with and its flys like a dream
are you using values below
Swash Mix
Ail +65
Ele + 65
Pitch + 65
