Align 3G
3GX setup help using Futaba

Hi Guys,

I'm doing my first setup on an align system, I'm using the stock 3GX that comes with the 450 pro v2 and I'm going nuts

When I set the hei without using the 3GX all seems well. When I connect the 3GX as per the manual to a R617 rx, the surfaces ( ELE and AIL) move incorrectly. I tried playing around with the reverse function on my 8FG and cannot come right.

Also noticed that the 3GX connects to the RX using a different allocation example ch 6 on the rx is used for throttle and 3 for pitch , normally ch 3 is the throttle and 6 is pitch.

Does this mean that I must change the function settings on the radio and make ch 3 the pitch and ch 6 throttle.

Any other suggestions will be appreciated

Not sure about your 7ch rx but I am using a 6ch and plugged the throttle in 3 and pitch in 6 and it works fine. I think the rev on 3 and 6 is more for sbus.

Keep playing with the rev on the servos tell you get them all moving in the right direction even if the swash is moving in the wrong dir. Then you can use the % in thhe swash menu to correct them. Also make sure you 8fg is set for H3 in the swash menu.

Hi,

I have other issues with the 3GX :

1. When in gyro mode and when I move the pitch up and down the servos are slow to respond. When I go into DIR / Setup mode the servos respond quick.

2. I'm battling to reverse the direction of the aileron compensation. Did what the manual mentions , i went into setup mode , then to A.REV , moved the ail sticks but the status light did not change colour.

3. How to I get out of GOV mode, the GOV light is green.


Thanks

Thanks Guys,

I found my mistake. It was at the very beginning at 1.1 of the FBL setup.
I was not pressing the setup button and then powering the RX , I was powering the RX then pressing the setup button, hence always going into rudder setup. Cannot believe that I was doing this since last Saturday, repeated my mistake about 10 times plus.

Now I have another issue I stripped the thread where the pitch gauge / button head mounts

I would never put a headd botton there again but if it is just for the little flybar/pitch gauge thingy just use a little ca to hold the bolt well you do your setup.

Glad you got it all fixed up!

Now I have another issue I stripped the thread where the pitch gauge / button head mounts
Use a cap screw with a longer thread. There should be a couple of clean threads below the stripped threads. Just be careful to not over tighten it.

Just a quick question to see if my 3GX is defective. I'm still setting things up, not completely built yet. Should anything light up on 3GX unit when you power it up? Or should I bind the futaba receiver first? I have my 3GX connected to futaba R6208SB through S.Bus. I was trying to update 3GX but I get no light or any response from the unit. The LED on the futaba receiver lights up, but nothing lights up on 3GX. Is it defective? Thanks for your help. This thing is kinda driving me nuts.

I am switching my Trex 550 converted to 3GX from my JR 9303 to my new Futaba 8FG Super using S Bus. I am starting to get the hang of the radio but still have a lot more to learn. The 3GX uses aux 2 from my JR radio to select rate and hh modes and to adjust the gains. How do I make adjustments to the 8FG and also I would like to set the switch for the gyro to switch SB if possible for rate and hh modes. I will get this radio figured out eventually. I am the only one in my area that is using this combination. I have one sponsored pilot in the area that uses the 8FG and is great with it,but not with Align. I will be getting with him to help me through any other rough spots I have. Also right now I am just making the initial adjustments in the transmitter and haven't hooked up this radio to it yet. I want to make sure I understand the settings first. Thanks for the help and back to learning. Chuck
