3GX DIR settings not saving

[PilotPhil]

I have all my settings in DIR setup mode working bob on, but the moment you leave the DIR setup process it goes back to how it was without settings applied ie all over the place.

enter DIR AGAIN and everything is as it was setup, leave again goes back to screwed up again.

why is the 3GX not transfering its setup process when finished?????

not only that no matter how many times i go through the rudder setup process the rudder remains mental as if it wants to rip itself off, slight touch of the sticks and it shoots left or right like a rocket


3gx = absoloute piece of crap!

Agree its a piece of shit, just buy v-bar and be done with it.

[PilotPhil]

haha! thats not helping me right now, vbarto much for a 550, beastx wont leave me feeling robbed

Feeling robbed? buy once buy correct, beastx is ok but make no mistake it aint no v-bar

Hey.

Baring a duff unit, most 3GX setup issues are down to user error. Setup couldn't be simpler.

Ok, so you enter DIR and obtain your desired pitch and cyclic ranges, then leave the collective stick at mid stick and press the button to move onto Aileron Limit set etc. etc. Have you gone through the complete setup steps after initially entering DIR mode?

Does the tail gyro operate in the correct direction with stick inputs and swinging the models nose left and right?

I have read some problems after setup can be fixed with a rebind, perhaps try this after the above.

Phil when you say the tail is trying to rip itself off shooting left and right are you seeing the tail seemingly not responding in a linear way to your stick inputs? At first this is disconcerting, but its normal heading hold behaviour! The gyro is trying to establish a set rotation rate and with the heli sat on the bench it can't do that so feeds in more control movement until it hits the stop. If you reverse the stick input it will then make its way to the other stop in its attempt to establish a rotation in the other direction. Center stick will not necessarily mean servo centre!

The roll and pitch axis gyros will work the same way, but in a less pronounced way. Moving the heli should make the swash servos move - even with no stick input! And the swash servos won't respond in a linear way to stick input. There's a lot of little computers in between trying to make the heli move in a certain way!

Not sure if this is what you are seeing, but if so its not a problem, its the 3gx doing its job! A vbar would do the same!

Could just be a dud unit though!

A slight input on the rudder stick should move the tail slowly not fully to the left or right very fast, that is not correct and v-bar would NOT do this, nor would any decient fbl controller.

[squareben]

Nor do either of my 3gxs, but I just thought it seemed possible Phil is misunderstanding what the 3gx is doing having never setup a heli before!

Just trying to be helpful rather than responding to every 3gx issue with 'just buy a vbar'!

Ross me old mate.
You are a top bloke and I really enjoy your company when we fly. But please stop knocking everything that ain't top of the line kit like the 3GX. Yes a few people have had probs with the unit but there are thousands including myself that are more than happy with it. It's more than capable for the majority. And let's face it most probs are probably down to setup. We all know it ain't a v-bar but at over double the price the v-bar should be great. I bet it ain't double the performance. We can't all afford a v-bar on top of the already expensive kit we've purchased.
My 3gx set up perfectly first time without issue. Now I just need to get a proper understanding of the software and tweak it to my liking.
And let's not forget that probably the best pilot in this country, and probably world class, Duncan Osbourne uses 3g / 3gx. I don't see him having any issues with it when he's flying.
No hard feeling Ross mate. Just a little rant from a happy 3gx user.

Rich,
If i hadn't owned and tried a 3gx for myself i would not post, but i did and from my experience it was awful, the original poster said it was absolute piece of crap (his words not mine) if he thinks like this why cant i say buy a v-bar?

All your comments are really helpful, And while im down about the 3gx I am looking at upgrading when back in the country i may, I think once ive got my head round things and im shown its user error then I will be happier, but for now its really confusing and I feel im following the 3gx instructions properly as advised.

rebind didnt work and the tail still wants to fly to the left or right with about 10% movement left or right on the sticks. ive adjusted all my links for the new DFC head so I will have to level the swash again tomorrow. I had a quick spin up and about 30% it was bouncing all over the place on the floor somethings very wrong there, could be main gear as that appears warpped.

I have a 3gx and I do not understand what Pilotphil is talking about, in direct mode you are only dealing with setting up the mechanical part of the helicopter, in a way the flybarless unit is not connected at this point, it is not until you enter the next step of the set up do you start to engage the electronics of the unit
It sounds to me that his problem is the mechanical set up of the servos themselves, they are not all going in the same direction, once you get your head round it the set up is quite easy, swash set up is 120 degrees in your transmitter

After reading your other thread, it sounds like you are trying to run before you can walk. Please don't take that the wrong way
Mine setup perfect first time without issue. It' sounds like this is down to mechanical setup. Is there anyone experienced in your area that could come help you out with setup? As a newb it's very difficult getting any heli set up right the first time and a FBL unit whatever make is in my opinion another step up again in the whole learning curve.
Sorry I can't be any help at the moment but something may twig later in the thread and I could hopefully help. Don't give up on it yet. Also if you were to install a BX or even a v-bar, if your mechanical setup ain't right to start with then they ain't going to be any easier to get working right.

Ross,
you did say it was a piece of shit in post 2 of this thread.
With all due respect to the thread starter, he is new to heli flying, is not experienced in setting up any heli stuff and probably for a good while yet will never know the difference between all the FBL units on the market. He's already thrown shed loads of money on upgrades that a newb prob don't need. Banging another 300 quid on a v-bar ain't going to get him running any quicker if the basics ain't right to start with. If the mechanics ain't right then the v-bar will throw it's toys out the pram and he'll think thats a bag of poo as well.
PilotPhil looks dead keen and willing to put the time in, so it will all click one day

Anyhow, what heli did you set it up on? Maybe you had a faulty unit? Did you give it enough chance before dismissing it? Did you play with the settings etc?
I agree, a v-bar it is not, but it's a long long way from being crap. As thousands of others will testify. Seeing Duncan flying one the way he does proves this beyond doubt and many other brilliant stick bangers using them in this world.
I'd love a v-bar and a logo 600 to go with it but unfortunately my money has to go elsewhere as well as my heli habit.
We just need to agree to disagree Ross. You love your v-bar (and so do I). You don't like 3gx or beast x. Just not to your liking. Not crap though matey.
See you up the field soon young man for some great company and laughs (and flying maybe)
