3GX v4 Setup

[tourerjim]

Done the v4 update on my 450 first as I'm not able to get over to the club to test fly the bigger ones & notice that 3gx doesn't default when going from 3.1 to v4 which suggests it stores tx inputs so cut long story short I also ended up defaulting tx because the tail still felt like it was on 3.1 & now its as it should be feels better than ever since Align went to v3.
So if any of you are struggling in some way setting up then default tx & go back through dir & gov setup, then I back through tail setup as well.
I'll try & get out first thing see how she 3d's, i just hovered with some circuits outside it does give you your confidence back.

What did you 'reset' on the tail to get it performing better?

[tourerjim]

Going through the tail setup twice & each time even playing with parameters it was as I mentioned same as when I was on 3.1, its only when I default my tx & went through the complete setup again that the tail seems perfect, just done another pack & haven't needed to use parameters.
So the only person that could answers this better than me is Ian (coolice).maybe.

Not really sure what you mean? Are the V3.1 settings saved when updating to V4 or do they revert to default settings? The Align site says that the settings will revert back to default settings, so is this true?
What do you mean by "defaulting my Tx"? Do you mean just creating a new model and starting again from scratch?
I'm planning on updating this weekend, but previous updates have only really needed a redo of the DIR Setup settings. not everything? So has this changed?

I've not read the Align's site info, mine through the pc software shows im now on v4 but when I went to fly her she was flying as if still on 3.1, only when I default my tx model & re entered new tx setup details as I went through dir & then tail setup did it fly completely different.
So not sure if its just me but I got 4 more heli with 3gx so be interesting how I get on with them but now makes me wonder if that's been a previous history as ive had no real problems on v2+ until I went v3 or higher.

Also as prove of this my 3gx is mounted inverted & it did not default the anti torque compensation when i went v4, it remained 'red' when default is green

Interesting and strange? Just out of interest did you fully uninstall V3.1 first before installing V4.0? It sounds like something is getting confused between the versions on your PC, i know the V4 installs new drivers too which is new.
I did the upgrade today and followed Aligns advice fully, backed up settings file, put the Gain pots back to 12 O'Clock position, uninstalled V3.1, did restart, installed V4.0, installed new drivers and did another restart to be safe.
No problems noticed this end, everything seems fine to me and all my 3GX settings have been preserved, all except for one that i noticed and has been talked about in this forum - The Rudder Gyro Gain settings were reduced from my previous 30 to 20 in the software (38% in DX8 Tx)
I think this was intended by Align so will only know if i need to raise it again after i test fly it.
I also had to go through the ESC/BEC setup procedure again, the throttle calibration, fail safe setup as well as DIR setup and Gyro settings as suggested by Align, so technically they are right in that upgrading to V4.0 will default your settings but as long as you save your 3GX settings file before updating it's not really a pain at all.
Fingers crossed she fly's ok when i get to test her fully tomorrow hopefully.

Hey Jim.

On all the 3GX's I've updated the firmware on, all have remembered their settings I had programmed before. However to be safe and knowing it only takes a short while once you know how, I always go back through DIR mode setup and the tail gyro parameter menu to be safe.

One thing I have noticed with V4 is that where before on previous firmware's I could run the aileron gain slightly higher than the elevator, this is no longer the case, with both gain pots needing to be set the same now.

Another one is that on landing the swash plate can tilt back, given a little time the swash plate return does take place and the swash levels out again. But having been given the transmitter by Duncan to try the settings I was working to tune, I observed the dreaded tilting on take off.
Later on while walking up to the model to retrieve it I noticed the swash plate tilting and also it then returning back to level again, so it's just something I'd like to make people aware of should they land for a moment and take off again.

Great info Coolice, will watch out for swash tilting.

Ian I new my 3gx kept the previous memory settings by the way it flew after going though the dir setup after going v4 so me thinking i needed to reset the tx model in fact i didn't need to because going by what your saying when i went through the dir the second time would have cleared the memory.?

Not experienced the swash tilt as yet but i will keep an eye on it now.

Have you managed to fly yours yet.?

Yes, flew great, better than ever before and i'm really happy with V4 so far

Not had chance to fly mine since but since converting my 250 back to 3gx i'm convinced Align have cracked it with v4

Finally got a flight on the new V4 update this am. Too windy by far for a thorough workout but initial thoughts are-she's mighty fast on the cyclic. Rolls are 'blurr' fast, tic tocs seem to be easier with less correction being needed. Did a few flips & loops also but wasn't willing to push too hard.
Will wait for a day when its not blowing 15-25mph for a more thorough test flight & then perhaps tweak then.
BTW I've fitted some softer CYB head dampers just to see if they smooth out the very direct DFC head a little. Red fitted at mo but also have greens (a little harder) to try.

[tourerjim]

V4 ive noticed has gone back using some of v2.1's imo so flight feel is more direct but with the parameters you can get better results than on version 3's, if you are not happy with your next flight i can pm my 450 parameter setup.
