Is align 3GX as bad as it appears?

[coolice]

one for coolice
3g on a shuttle mechanicaly mixed flew perfect fbl no-bar (no electronics)
hands off the sticks in the hover with zero trim or sub trim (yes a shuttle set up that well)
gy401 on the tail in rate mode no drift
ds620's on cyclis and pitch
ds650 on the tail

i fitted a 3g onto it and the heli on take it off shot the tail down
controling out of this to get into a hover the tail kept trying to drop and the tail not holding at all in hh mode
the 3g was taken off at the field a 401 dropped in and it flew perfect again no-bar
until i crashed it being stupid

the 3g was fitted to the std shuttle gyro location at the back of the fuel tank/in front of the engine

why has the 3g made a perfectly set up heli do this?
as i'd like to at least have an idea whats wrong
the swah held level once turned on and left alone (aafter the start up jumping up/down) all the swash directions were checked and ok with a flatish ground when attempted to set the heli up

the sk360's i've used are just a set up to the base setting and fine tune to suit with no trim change from no-bar

Hey.

Hmmm, strange one. I will assume you went all through the DIR setup mode once the 3G had been fitted and also started from a clean model memory when fitting the 3G to the model and before commencing setup?
The latter has proven to be a real problem in the past, using an already setup model memory and just adjusting various parameters to suit the 3G installation.

During DIR mode the 3G/GX learns what CCPm setup it is working with, be it mechanical or electronic CCPM mixing, which is why I asked if the DIR setup had been done.

Was this unit fitted to another model and it worked all ok in that machine?

As mentioned vibration can be a real problem for some units, however as the GY401 seems to work ok in this location one would assume this gyro location is all ok to use for FBL to. Have you observed the 3G/servo's when the motor is running to see if anything untoward is happening?

The only possible problem there was with the 3G was the connecting lead between sensor and main unit, some experienced connection problems, I was one of them when my 700N flipped out in flight

Honest opinion:

Me and Mat Brown have been trying to get the 3GX to fly half decently on his 450 Pro. For weeks now - I think even months? We've been trying and it flies like absolute crap.

I'm sorry but align has made the unit complicated with the settings, So many sliders and options for what?

He flies through it, and surprisingly pretty well, I refuse the hover the damn thing it's that bad.

If Align had made the configuration more user friendly and more understandable I think most people could iron out most issues.

Perhaps if it was on a bigger machine it would be better, But even on a 500 the pirouette and the consistancy of the whole flight characteristics were not good.

Hey.

What blades were you flying on the 450? This I found to be more critical on the 450's, even the Beastx's are reknowned to be a problem on the 450's with many fitting Vbar's to get them flying nice. The smaller models are less tolerant to not havign all the right ingredients to make for a good FBL setup.

The 3G/GX settings I feel suit the flier with a good understanding of how to properly setup a flybarred machine, making use of the various control ball positions, bell/hiller mix options and paddles weights etc. as this is what is simulated if you like in electronic form via the sliders. Without this knowledge it's going to much mroe difficult for someone to detect and fix certain issues if they do not know what effect on flight feel a given slider does.
This makes the unit less attractive to fliers as all we want to do is go fly, I spent many flights with the 3G/GX just flying tweeking and flying some more to come to the settings files I have posted on the forums.

Speaking of which have you tried mine on the model? Which combiend with some FBL blades will make a vast improvement if you've not already done so.


With the 3GX, some members of the MK club have recently not been too happy with their models, on writing my settings to the units they feel so much more confident in the models and happier with them as a result.

Align kit is usually reliable, but I see these 3GX units for sale 2nd hand unused everywhere.

I've read some horror stories but many seem to be power related.
Are they really that bad?

well I cant really compare them nor their features ... I have however upgraded my 500 and 600ESP to 3GX and cant really complain, I did follow the advice to use another BEC though on the 600ESP, apart from that - just works for me ...

actually I put them on nearly after the upgrade of the 600 and must admit - they cured the little tail wag I had left - the 500 however was spot on from my perspective all the time, I did put them on anyway its a bit different now on elevator and aileron but feels nicer ... so +1 for Ian's settings ...

yes the DIR set up was done and with a new model memory
(as I use very reduced cyclic movement with the no-bar set up and I wished to keep my no-bar settings )

with the engine running the servo's didn't do anything abnormal
and the 3g was a new, unused one out of a kit from Fast Lad's

the tx stick to swash movement was correct and the gyro effect was operating in the correct direction on the swash

Hey.

I thought you would have done so, but it's the first thing to ask.

Looking at pictures of the Shuttle, the gyro was mounted almost directly under the mainshaft?
Can you perhaps try it again in a different location? The only logical answer is vibration at this time, so by moving it to a different location, perhaps up and behind the mainshaft or at the very front, we can try and eliminate one possible cause.

Failing that, are you coming to the MK flyin? If we've not sorted it our by then I'd like to see it and have a go at fixing it.

i don't know yet if i can make mk
i'll move the unit and try again
but i do need to repair the head after the crash flying no-bar
its bent the one control arm off the metal blade grip
but it won't take long to make a new one

My 2p for what its worth

Having a 450 which is converted to FBL with a 3GX and a 500 with a 3G i can say that i found the 3G much nicer to fly.

I have now sold the 3GX and have installed a BeastX and its 100 times better but I still cant get it perfect, still has a wobble when flying about even slowly (getting to the point to go back to FB on the 450)

I have also installed a BeastX on the 500 and its loads better than the 3G.

I noticed exactly what Jamie has mentioned, the 3G was nice and smooth with gentle flying but as soon as I pressed on (even to my limited abilities) it would get itself out of shape and get a jerky.

Having limited setup experiance I wasnt getting anywhere so decided to move to a system that was better known

I couldn't get the beastx completely stable without a little boogie going on either, initially. Changed stock servos to HS5065MGs and was perfect (no more stripped servo gears either).

Already got the HS5065MG's on the 450 although they seem to have slight play, probably from a few early crashes I made her suffer with.

Hi Guys. the setting were
Heriiza80 of HF
Tbh I felt like my worn out Flybarred pro lol
Flown smooth it's fine I actually quite enjoyed it.
But if your aggressive it's unbelievable bad.
I then took my Vbared 700 out which just FEELS quality.
Thanks to Sackos payment plan, cheers bud. It's gona have a rather yummy Mini V wohooo

[BenScoobert]

So to conclude.......anyone got a beastx for sale?

Thanks for all the comments everyone, this will be my 1st flybarless (except MCPX but I don't count that) so I think simpler setup is a good idea and we can reduce the "what if" factor.

IMO its all down to setup. I don't think they are that bad at all - I'd say they need a bit more tweaking than say a beast x or a v-bar, but they are a good unit. People still slate the original 3g unit, but if you have ever seen Duncan Osbourne fly his one - looks pretty good to me!?

well Duncan could fly a roll of toilet paper if it had a rotor disc
