Align 3gx V5

[coolice]

Thanks ian

no gyro set to gear in main set up menu, as no other option, in gyro menu set to aux 2 and gyro sw, worked perfectly until I started trying to update it,

also Ian it was working properly before I started this process,

think I might rebind later see if that makes a diff, if not clear model memory and start again, not ideal but might have to.

on another note, hovered in garage an the bird feels alive, much more direct feeling of the swash and changes direction smoother and quicker and after setting tail up in rate mode it was crisp and tbh feels faster than it did before,

test flight tonight after rudder limit setup and rebind/rebuild of profile, need to get this gov light sorted but could fly in pos 2 on my gyro switch as that seems to be working OK

Hey Buddy.

You're welcome.

Yeah I read your first post saying it was ok until the update, to my knowledge Align haven't switched the gyro gain operating channels around, so the first thing that popped into my head was the controlling channel being wrong.

A rebind won't hurt, there has been occasions where this fixes problems.

Keep me posted.

The Align set up instructions has a warning about this specifically saying that if the swash tilts after entering DIR to go through the DIR initiation process again. My assumption is that although the gyros are disabled once you are in DIR, when you actually enter DIR they go through a callibration process.

If the unit is inverted you can turn the heli over to get access, providing you dont move the unit diring the actual DIR initiation.

Hey Buddy.

James_sk is correct, in DIR mode moving the model won't make any difference. However you are also correct in that the 3GX does enter a sort of calibration mode while in DIR, actually to be more precise it does this when you press the button for the first time to advance to A.Lim(?).
The requirement and should probably be added to your advice above to someone else is to enter DIR mode, then centre all the controls/sticks, before then pressing the 3GX set button to advance to the next step. As it is this first press that teaches the 3GX the model & transmitters set neutral positions and stores the chosen swash plate type setting, eg. mCCPm or eCCPM.

Ideally you need to enter DIR mode, centre the sticks and press the rubber button to store the neutral points and away you go. If the remaining DIR options have been set, A.Lim, A.Rev, E.Lim, E.Rev, then you can just press the button to skip over these. But for the few seconds it takes to go through these again, I think it's worth doing to avoid potential problems.

yeah cheers Ian, will try what I have said, confirmed my switch was not to blame as worked perfectly on my 500 3gx unit which is set up exactly the same, only had this problem as I said while trying to do the update which failed so many times, worst case I can fly in pos 2 and adjust gain as required,

but rebind will be first on the list of 2 do's

The tilting may be because you moved the heli / FBL unit slightly when entering DIR mode (easy to do when pressing the button), which I believe means the gyro calibration gets screwed up. If you just go into DIR again making sure not to move the heli or FBL unit at all, you don't have to change any settings, just enter DIR mode then come out again.

This is one of the reasons I dont want to re-set the DIR again when all the settings are already correct and working ok, fixing something that isn't broken is just an opportunity to screw things up.

Nope!
The gyro is disabled in DIR as mentioned by Coolice but I have done this procedure many times before without any such issues as I'm getting now.
It is always advisable to go through setup procedures again after every major update as recommended by Align and I always did without issue although not necessary in some cases better to be safe than sorry.
My 450 is still acting weird since V5

[Slobberdog]

Well I have V5 installed and working and to resolve my issue with the gov light I had to create a new model and start a fresh, so some how my model got corrupted a bit in my tx to gyro

[james_2k]

Same happened to me. Difference was mine wouldn't even boot with the old profile. Details earlier in this thread

yes, as per my previous reply to the same point. Gyro is disabled when in DIR mode but according to Align themselves is calibrated during DIR initiation, and if the heli is moved at this moment the swash will tilt afterward

You dont need to take my word for it, take Align's. Here's an extract from the manual that I included in my previous reply. This is from page 25 of the trex 600pro manual in the section dealing with entering DIR mode:

Well I got two batteries through the beast tonight, lol beast, the 450 was horrible for me on V4 so I was a bit apprehensive to go to V5


But done my final bits tonight which included raising a new model in my tx to cure the gov light issue as a re bind did not


First flight I spooled up and the heli got light on its skids and a fair bit more twitchy on my heli pad but did not move the head at all, so maybe a bit more ground savvy, got it off the deck with a sharp prod and into IU, BOOM it felt very solid, tail as I found in my test hover was sharp and crisp, stopped very sharp and even the tail on climb out was solid with zero kick out, I did however get a couple of twitches on the tail in the first couple of mins of flight but then nothing after that,


Cyclic feels very direct and sharp, so much so I went up a couple of % on my expo! it feels like the role rates were more responsive and coming to a stall stop at what ever angle felt safe and controllable


Flight 2 was much the same as the first but getting used to the feel very quick it was really enjoyable to fly, as others have said it feels very fluid which is a great way to put it, it defo does not feel like it has to think about a change in direction it just does it.


Very pleased with it at the moment but do want to get more packs through this heli before I shove the other two onto V5

Although I have a different issue I think this is the steps I need to follow and redo everything. I've done a lot of upgrades on 3gx and know the procedure well enough so it must be something like this that's going on.
Anyone else had to reset Tx settings and create a new model for whatever reason when upgrading?

Align 3gx V5

@Grumpy
Thanks but I never move the Heli during initialisation and the swash definitely isn't tilting. What I am seeing here is something very strange and new to me in 3gx world.
Some others have mentioned possible corrupt Tx settings after the upgrade and by creating a new model and starting fresh resolved the problems, so I think this is where I need to look further.
Still curious if anyone needed to up their gains considerably or not after V5?

ok, i've been out and flown my 500, 600 ands 700 helis with 3GX installed on each. There is a big change; gyro elevator and aileron gains needed turning up dramatically on all three helis but especially so on the bigger helis. On the old gains which previously flew fine, the bigger helis especially felt unstable and loose, drifting all over the place in hover and not pleasant at all to fly. Unfortunately I didn't have the little plastic adjusting tool for the gain pots with me so i only got limited adjustment by using a screwdriver, it wasn't enough to get stability back to where it was previously.

No settings had been changed except for flashing the new firmware. I'll try again tomorrow and crank up the gains all the way and see where that gets me.

I'm found adjusting cyclic pitch dampening is better than using gain pots which also seems even more responsive on v5, i started by going 50% & going + or - to get best results

Interesting, sounds very much like the issues I was having
Higher gains also helped me but didn't fix it totally.

I Updated a friends 3gx from 4.0 to 5.0 yesterday , I Didn't do anything other than disconnect it. Everything worked has it should and he said it flew fine. Only problem he had was when he got to the field and forgot hes Lipo's . Had to use mine instead

Odd that we are having different experiences. The gyro gains on all three of mine were as if turned almost off, most noticable in the 600 and 700 size but there on the 500 too to a lesser extent. Possibly on a smaller heli (450 maybe?) the change is not noticable?

I also didnt make any changes other than flashing the firmware, so it's not some other inadvertant setting change.

I am using a 450 and it is very noticeable
