Thanks again for all your help, I checked the 3Gx v4 software on the pc and it doesn't appear to come with any ability to roll it back to 3.1 so I'll have to download the earlier software file then install it to the 3gx.

It a shame align don't seem to have made these issues very public.

Is it best to set the tail up in rate mode with 3.1 or just follow the manual.

Regards Chris

It won' t hurt to set the tail up in rate mode to eliminate any yaw while hovering. Once you do that you can go back and fly in heading hold mode.

Make sure the mechanics are good to go, make sure you have the gyro stuff set up properly, and give V3.1 a shot.

Hey Guys.

You can remove the tail overshoot/bounce back by setting up the tail trim in rate mode and reducing the delay value to zero, like has been mentioned.
Just this past week I have setup 3GX's on machines in the UK and with initial settings, none rate mode setup and delay at 30 initially, caused problems. Going back through the tail setup fixed the tail problems and the machines flew nice. I also drop the rudder locking gain to 45~50% as with past firmware's, this helps you be able to raise transmitter gyro gain. I also run shorter tail servo arm lengths than the Align recommend, another factor for being able to achieve a nicer tail. This was on V4.

On my own 450L I'm still using the teams test V4.1, I have been chasing in the UK to find out what's going on, but there has been no mention of a release.

Hi ya

I have tried all the points mentioned other than reducing the servo arm length but none seem to work.
I ended up with rudder locking gain at 45, tx gain ended up at 90 to keep the tail feeling solid but still suffered bounce back, ive also adjusted the rudder delay but this then brings an unequal amount of bounce back. One thing I did notice was that the 3gx v4 software only appears to see the gain input fron the transmitter at half the value its actually set to.
Gyro is set to aux2 90 gain on tx is only indicated at 45-50 in the 3gx software. Could this be part of the issue.

It would be in Align's best interest to release a new version of firmware to address the heading hold gyro function. The V4.0 release has been out since late summer 2013.

The V4.0 release also exhibits some odd behavior while in the setup modes. The most serious is periodic glitches in all servo outputs. Last fall, while trying to get the V4.0 gyro stuff to work, I experienced one of those glitches which suddenly began to spool up the motor. That was a real eye opener.

I have also seen V4.0 randomly exhibit what looks to be a power up reset while in the setup modes. In the middle of doing something the unit shuts off then comes back as if power had been interrupted. Power to the unit came from a 2S LiFe pack connected to the two lower horizontal 3GX connectors so the power source was not interrupted nor did the voltage sag below 3.5 V.

When installing the 3GX using a single satellite receiver, if the satellite is plugged into the ANT1 port, the unit won't complete the bind process. You have to use the ANT2 port instead.

The electronic cyclic ring in the PC software does not work.

Setting zero rudder delay seems to default to "30" unless you know the secret handshake. I do know the secret handshake but one shouldn't have to.

Most of these are just nits and I still like the 3GX unit. But Align who seems to introduce kit upgrades on an hourly basis is dragging its feet on an improved V4.0 release that would be simple to set up and that doesn't take repeated screwing around with to get "right".

I think I'm tired of waiting for 4.1.

I bought a 3gx when 4.0 came out because I thought I could use it with DSMX satellites. I never installed 4.0, because of this discussion.

I set up my new machine with 3.1.
I'm not satisfied with the servo twitching I see on 3.1. Also, the failsafe behavior leaves a lot to be desired. (unfriendly failsafe: kill the engine on any lockout.)

I've sat on this heli project, unfinished for months, waiting for 4.1 to become available. It doesn't look like a release is imminent.

So I'm thinking of pulling the 3gx and putting in an iKon that I also have. At least I can get this heli into the air.

I suppose anybody who knows can't say exactly when 4.1 will be ready... So as soon as I pull the 3gx off my heli, and unplug the wires, then they will release it.

So here goes... You can thank me later.

Based on that statement, it's pretty clear you didn't bother to actually look at the V4.0 PC software regarding setting up failsafe with Spektrum satellite receivers.

V3.1 failsafe is the SAME failsafe setting you get with MOST Spektrum receivers. Hold last position, and the throttle channel failsafe position is set at the time of binding, by the position your throttle stick happens to be. If your throttle was set to kill the motor position when you bound, that is where it goes during failsafe.

But also note that V4.0 included the standard Hold Last Position with throttle to go to the position the throttle stick is set to at time of binding (already present in V3.1), but if you follow the instructions, you can ALSO have the 3GX use PRE-SET positions for servos during failsafe (introduced with V4.0).

V4.0 does support DSMx satellite receivers.

Perhaps instead of waiting months for a release you:

A) go ahead and see how V4.0 behaves for you (of course, set up the failsafe correctly before you go)

B) give V3.1 a shot. V3.1 is very solid and just works. If you try V3.1, remember to set your throttle where you want it to go when you bind, as with most Spektrum receivers.

-----

The ten installations I have with the 3GX, all currently dialed back to V3.1 work very well. Helis ranging in size from Trex 250, Gaui NX4, 450, 500, 550, 600N and 700N, no problems here with V3.1.

Thanks Dave,

It's been sitting in the bench so long, I'm not exactly sure how much of that I've tried. I do remember that I could not figure out how to get the throttle to go to idle on lockout. That was the one thing that keeps me from trying 3.1. I'm sure it would be different if I were using a proper receiver, but I was excited to make it work with just satellites.

I have DSMX satellites only. I wasn't sure they would work with 3.1. I see the twitchy servos on the bench (does that go away with 4.0?)...and that doesn't give me a lot of confidence either.

Correct. Never installed it. Is it worth it to try and fly it? ...or just as an academic adventure on the bench.

Hey guys.

There has always been two types of fail safe on the 3GX from V1.1 onwards.

1. Throttle only failsafe and all other controls last position hold. Or,
2. All channel user set failsafe, activated by removing the bind plug from 3GX before following usual binding procedure from transmitter.

The above mirrors most Spektrum receivers from the AR7000 and above that also offer two fail safe types.

In the UK it is mandatory to have your throttle go to idle (IC engines) or off for electric in any fail safe situation. I'm sure the US is similar?

DSMX binding capability was introduced from V4, previously DSMX sats could be used but would bind in DSM2 mode only.

The twitching is still evident in the beta V4.1 I'm using, throttle channel also as I've been whacked and had my finger pinched when it pulsed the throttle. This has been relayed to Align from us UK testers, no word yet on a new firmware.
V3.1 only exhibits servo twitching in DIR mode from what I've heard over here, not been seen in flight mode. V4 shows it in flight mode when the model has been powered for a short time.

V4 does fly well once setup, it's no Vbar but in the right hands will still do the book.

fyi - DSMX satellites have always worked with the 3GX since they were released - they just bind in DSM2 mode.

twitchy servos sounds like a different issue. I would suspect your power system isn't supplying high enough voltage under load.

Hey Buddy.

Separate BEC on my 450L and also seen twitch on Trex 800 with straight 2s LiPo.
It doesn't happen right away, but seems to build up and then start twitching. I think it's the feedback loops being set just that little bit too high and the 3GX sensors are looking for movement even when the model is stationary.

Ah, yes, sounds like you've done a lot of looking and thinking on this - I haven't seen the twitchy servos on any of mine but I don't push the settings much beyond factory settings, perhaps that makes a difference? or do you leave the 3GX near factory default settings?

Version 3.1 head holding not working well for me
I am using version 3.1 software and am thinking of upgrading to V4.1 because I am not happy with the current situation of the head locking but after I have seen the discussions, I am having 2nd thought.

Anyway, I want to understanding better what the rudder parameters mean in version 3.1 first.

I am using Specktrum DX6i. This is the Rudder parameter screen showing my current set up on the 450.

Note that I have set Rudder locking gain to 90 to make it work reasonably well. If I leave it at 50%, it is not holding at all.

I set my TX Gyro gain to 80. I see that the Setting Display screen shows 44 for Rudder gain. If I set TX Gyro gain to 100, it will display 76.

Can someone explain to me how these different controls are used, how those numbers are calculated and what would be a typical set up?

Hi chancol,

You mention that you are using version 3.1 but your screen shots shows 4.0.. You might want to downgrade to 3.1 as you are probably experimenting the same problem that some of us had with 4.0. For my heli, Trex 600 NSP, 4.0 was not working properly for tail control and by simply downgrading to 3.1 the problem disapeared.

Hi,

The firmware is 4.0, the desktop application is V3.1. Look at the top left hand corner and you'll see.

Before going much further, you have a DX6i transmitter. What are you using for a receiver?

-----

Took a quick look at the V3.1 and V4.0 PC GUI side by side, no difference in parameters you can set, values you can set, or how the program operates. The V3.1 PC GUI should work the same if you're using V3.1 or V4.0 firmware.

I am using the OrangeRx conventional receiver from hobby king.

I have read the discussion a bit more carefully and I think people are talking about V3.0 vs V4.0 firmware. The desktop application probably does not matter.

My plan for next steps:

1. Try as other suggested - lower the rudder lock gain and adjust TX gyro gain and see what difference it makes

2. Downgrade to firmware 3.0 and see how it behaves.

I still like to understand what rudder lock gain is and how it is different from the TX gyro gain.
