programming manual does it say how to set this. I would rather just do it on the pc but have not got the software uploaded yet.

Upon reading the manual I see there's a backwards sort of way of programming compared to other gyros out there.

Could Align have spent too much on developing something with too much to offer. It NEVER helps to make something complicated when it is something that is supposed to make another thing simpler, this case being removal of a flybar and substitute with a computer that takes a genius to understand. Align, it's best to dumb things down at first.

Can someone link the 3gx pc software here please?

My experience is with fb, AR7200BX, Tarot ZYX-S and Align gp780, that thing was very nice and easy to program, the 3gx is a multiple of it no doubt.

I found the 3gx setup mind numbingly simple myself, and I don't think you can set the basics from a PC, just the more advanced tunables. The software is version specific, and should have been on a cd that came with the unit, or can be found on the Align web site or with searches like 'align 3gx downloads' on the internet. (That will also get you to firmware upgrades).

I don't think it will support anything but normal and inverted - an it's side, the gyros are physically in the wrong planes to work.

To me, *NOT* needing a computer for setup is what makes things simpler . . . at least if the user can read at a decent level . . .

You can mount it right side up (button and label up), or you can mount it upside down (button and label down).

The LONG axis MUST be parallel to the length of the fuselage. The connector block can be mounted facing forward, or it can be mounted facing rearward.

There is NO support for mounting it any other way.

Setup of the 3GX is dirt simple.

As for a link to the PC instructions, if you downloaded the software update, you HAVE the PC instructions.

The download comes as a compressed .RAR file. Download it, unzip using WinRAR or 7ZIP, and click the SETUP file. Answer the questions that pop up along the way.

All the ones I've used are not side mountable, as per the instructions. If you load the 'set-up' software on your PC, the step by step instructions on setup aer there.
A quick google search for '3GX Manual' will bring up lots of links for downloadable files.
In a nutshell, make sure the motor has 2 wires un-plugged (no unplanned start up's). Power needs to got into 3GX, then to reciever if using a separate Rx. Sat's for Spectrum need to be of the same type (DSMX or DSM2 if using 2) & have been already bound to Tx.
Transmitter ~ Linear Pitch & Throttle curves (0-50-100) for the setup phase, 120 CPPM set, no fancy mixes. Swash will be used.
Servos need to be plugged into unit (and connecting wires to Rx) with Left servo as Pitch, Right servo as Aileron & Center as Elevator. Arms can be off servos for power-up.
Turn on Tx, push & hold SET button on 3GX, Plug in battery (OR turn on Power switch) then release SET button after 1st led lites up, and before the last LED lites.
Unit will be in 'SET-UP', move throttle stick on Transmitter to mid '0' position & mount servo arms as square to servo's or link geometry as possible.smallamounts of sub-trim may be used here, but I try not to use more than 15 points myself.
After link/swash geometry is @ '0' use a pitch gage & Tx Swash Pitch to get +/- 12-14 deg of collective. Then Tx Swash setup Aileron to have +/- 8 deg & make Elevator same as Aileron, within 3 or 4 points.
Now each time SET on the unit is pressed, the unit us set.
Tx Throttle stick @ '0', push set. Light should jump 1 spot. Move Elevator forward (Down) full, hold a sec, then back to center.
Push 'Set'. Lift tail of heli a bit & swash should move to stay level. If it moves same direction as nose is tiltiing, needs to be reversed by moving Elev. stick. When light changes color, it should be reversed. Press 'SET', move Aileron full Right, hold a sec then back to center. Press 'Set'. Roll heli a bit to the Right, swash should move to stay level. If it moves same direction as roll, reverse with aAileron same as previous. When correct, press 'SET'. All green lights now if unit is facing 'up', change to all 'red' if unit is facing 'down' (mounted inverted). Push 'SET' again & that should be it for the cyclic.
Go thru the Rudder set-up as per instructions & ready to test hover...

yea thanks, I realize the inevitable fact it is limited in how it can be mounted (-1 for this) and I'm looking for another place to put it (other than the trash can LOL). Does it really matter if wires are pointed forward or back? It came off a 700dfc and I recall the servo wires were toward the back. It's on my Shuttle zx nitro fbl conversion.

I put the tx in single servo normal mode, had it in 3 servos 120deg. The shuttle is converted to 120deg swash.

I know after it is understood it can be a simple gyro to set up. I did upload the manual.

I will cut and paste slowly so you can read my earlier answer:

A minus one? This thing is small enough to fit nicely between the frames of a Trex 250. Finding a horizontal flat spot to mount it shouldn't be a problem in a Shuttle or any helicopter.
I put the tx in single servo normal mode, had it in 3 servos 120deg.
and
The shuttle is converted to 120deg swash.
in the same paragraph.

Is there some reason you would purposely set the 3GX so it won't work with your Shuttle? If you have a 3-servo, 120 degree swash control system, that's what your transmitter MUST be set for with the 3GX. Otherwise you will have a very short first and only flight of your helicopter.

Yeah, mounting may not be the most convenient, but it must be mounted only as per instructions.
Change back to 120 Swash in Tx, as stated, or that will have a nasty result.. 3GX will use Tx signals to configure 3-servo vs single servo layout.

If access to the 'SET' button & top of unit is an issue, the unit can be set-up, then mounted in the heli.

In my 500, I mounted the unit on the receiver plate, and just un-mount the plate for setup leaving it all plugged-in. After that, as long as the 'data' port is accessible, it can be plugged into a computer for 'tweaking. I just use a small screwdriver to hold down 'SET' button if I have to power-up in setup or GYRO menu..

I don't remember layout in a stock shuttle, if the plugs are not fitting 'cuz they're not vertical, maybe a mount plate can be added somewhere? It needs to be rigidly attached to frames (screws / bolts) and on the centerline of the heli.

we're looking at an unconventional shuttle, forget it's a shuttle but a nitro fbl heli with bell cranks, a 3gx, and hv digital servos. Have swash as 120degree 3 servos and with a regular receiver got them to work proper ail/ele/pitch actuation's.
very short first and only flight of your helicopter.
that almost happened to a 450 I did not tighten the tail support mount screws on last night. A happy accident I can call it because it did something to involve a planned craft rolling around in my mind for several years. Tail vibrated and the gyro began to over react on the ground, STOP.

regarding the shuttle to 120

all I will do is fab a tab for the 3gx that will run off the guide (not seen in the pic) or put an angle on the mounting plate I fashioned for the shuttle earlier. Only problem I have is that the gyro came off a bird without bell cranks and it will have to be programmed from the start. The tank was put back right side up giving the gyro a nice wide area above it. Sticking the gyro to the tank is not something that's going to happen.

I've been scoping a lot of places to fly a nitro without attracting unwanted guests. A TT rapter (just a bunch of parts atm) may become nitro and is not going to remain fb either.

You'll get an updated photo shortly. There are weak spots on the shuttle frame being the legs between the base and top section. The frames have those holes for a e switch on both sides and the back section behind the motor has screw holes. I was considering adding some cf plate to strengthen these. If the frames were broken in a crash they would be fixed and wrapped with cf there or a side plate could also be made to join the top with the base. To me it's just another rotor system with a few different stylings. Performance wise I'm not too worried, it's not a hp platform and with an alu head it could do light 3d.

That's the hobby.
