Need help - 3G system will NOT initialized most of time when power up

[zci_zr]

I had this too, I set it up fine initially, but noticed it would fail more often than not. Got to the field and it would fire up at all. What I noticed was if i were to tinker with the plug on the controller unit (the one that goes to sensor) it would reboot. I nothiced that one of the female pins in the lead had somehow got damaged and could make a proper connection. The respective pin in the unit (black one to be precise) was ever so slightly pushed in a bit, which ended up opening up the unit to push it back out. I had a spare lead from another 3g and tried it out. Every now works perfect.
So make sure ALL leads are making proper connections, give them a wiggle to see if you get the reboot. Check pins in unit too. You may think they are seated ok but you may be missing simething. Even take it apart and take super special care to put the leads back in there correct place.

Just my findings, may not help you, but its worth a try. I almost wrote mine off, glad I didnt

Good luck

Hi Tony:

Thanks for your reply, I will try you suggestion tonight, I will pulls all wire and check the if the connection is tied. I will keep update tomorrow.

Once again, really appreciated your help.

Hey.

Having had a dodgy 3G lead I know there had been the odd bad one, to be safe as above pop out each pin and ever so lightly squeeze it with a pair of pliers. With the pins removed I recently went though each one trying them on a sensor pin and one was a loose fit even on a working model. It would be a simple task to ensure they are all well and good.

The intermittent initializing I've never had but I'm sure its spectrum related as stated above, try reminding the model again as I've heard this fixes this issue from memory.

Ad to the sensor mod all my 3G models have had it done but not one specifically benefited from it, you're meant to be able to up the gains but I certainly couldn't and doing the mod void your warranty. If your problems don't get fixed you might push for a replacement or check of you current system and if its been opened there will be no come back.

Definitely inspect the lead, on mine I've seen the black wire to be the misinserted/bent connector.
Then rebind the model to the transmitter and try the initializing process again.

What BEC are you running, an Align ESC? Also what voltage output?

Hi Ian:

Thanks for your reply.

May be you are right, the first time I am binding Rx to Tx was without any servo or 3G system connection (just Rx on its own), I have just rebind Rx with Tx again but with everything connected up, so far the system is initialized every time when I power up (touch the wood), but I will update tomorrow.

I am using the ESC that originally come with the combo set. Is 70A align one, it has BEC integrated, BEC output is 5-6v

Kind regards

You should allways rebind the Rx to the Tx after connecting eveything up so that the failsafe can be set with throttle at bottom stick and all other controls at neutral.

Hi:

Thanks for you help me on this thread too.

I will remember this from now on.

Also I am waiting for your reply on the other thread posted by me regarding with pitch setup, hope you have time to look at it.

Brilliant, nice to know its working.

Hi Rui.

Your very welcome, glad to help out buddy.

It sounds like it might just be a bind issue then if its working better so far, let's hope it stays that way and initializes first time from now on. Keep us updated.

For failsafe settings a like to set all my models to 0 degrees pitch and no power during a fail safe lockout, this way if the worst should happen the models not going to pitch upwards or down with negative pitch but gently float along and hopefully control will return to safely land.
You have to be quick but on turning on the transmitter to bind I flick into throttle hold to set no power and move my collective stick to mid position where it binds.

The Align ESC is perfectly fine, I guess your using Align serves to and if this is the case you can set the BEC output to 6 volts so as to have the serves meeting the recommended specs to work at their best with the 3G.

Keep us informed, my fingers are crossed :-)

Hi Mslater and Ian:

I have tried again this morning, the problem come back. Its the same with what happen before when I try to redo the update on 3G software. The 3G system will working fine until next day morning.

Anyway, I have rebind the Rx and Tx afterwards, everything seems working fine again. I am now really confused whether is the problem with the receiver or is the fault with 3G system; or may be is the compatibility issue between Align 3G and spektrum receiver, but I am sure I am not only one use this combination.

P.s. the new problem I have discovered is, when I power on the first time (after I been leave the heli alone for a moment), it's most likely to fail initialization. After re-power up, it may initialize but the tail servo arm alway keep in very end position on one side when under the HandingHold mode. However, I will get correction response when I tilt the heli in opposite horizontal direction is this case , but the servo arm will back to where it was when I stop moving the heli; it seems working fine if I swatch to rate mode. So I have power up few times to get everything working correctly.

Right now, I am really have no idea what should I do next.

Hi Phil

Thank you very much for your suggestion, Once I have sorted the problem with 3G system, I will definitely re-position the sensor as you suggested.

: ) Thank you.

Rui

The sensor needs to be as near to main shaft as poss on bottom tray for best result also best to keep 'Y' lead permanently connected so not having to connect/disconnect when doing firmware updates.

I've also have had times when the 3G doesn't initialise most time when I working on it indoors often have to leave TX where I'm sitting & take heli in the other room then it's ok, sometime at the field it will do it so I move heli or turn it abit then seems fine but I also read on couple forums mobile phone can cause it both mentioned only noticeable more indoors.
Also read on anther if you keep initialing it will not won't to initialise but is find once he was at the field.

Thanks, I will try that.

Currently, The 3G seems initialize fine at this moment, but I have power on twice to make everything work in order, because the gyro function seems always fail at first power up (but cyclic pitch function is fine and the state light will stay static, the swash plate will also jump three times)， the 3G gyro function unit will keep the tail servo arm in very end position on one side when under the HandingHold mode. However, I will get correction response when I tilt the heli in opposite horizontal direction is this case , but the servo arm will back to where it was when I stop moving the heli. If I switch to rate mode.

Is this happen on yours before when your 3G system had the problem?

Thanks

Rui

When swash plate jumps three times that's indicating that the 3G has initialized.
When in heading hold 'HH' tail will settle to one or other side so if you flick the gear switch' tail will/should centre" the other thing to double check at same time is tail gyro direction' holding heli nose end to your left holding tail in your right hand with putting finger against tail slider pull tail towards you slider should move away then checking swash movement tilting heli forward swash plate should tilt back then tilting sideways swash must tilt opposite way.
To be honest with you it don't sound as if your fully setup right just yet so wouldn't attempt to fly unless you sure as you must not have any interaction on the swash plate between neg zero & poss as this will greatly effect the way it takes off, I needed to us swash levelling tool as I kept getting what looks like main blades resonating when spooling up & taking off.
Any probs your welcome to pm me.

Hi:

I have checked every video tutorial on Youtube I can possible find, I am sure I haven't miss anything on 3g system setup and tail gyro setup. The problem doesn't happen every time.

I will explain the detail of the problem, when the problem happen, swash plate correction is correct and working in order, but just the gyro part. In HH, if I facing to heli from tail end, the gyro will keep tail rod in very left position (which will push the heli nose to right). It will nothing happen if tilt the heli to right or left horizontally. If I switch to rate mode, tail rod will not keep in the center, it will keep at very left (but not in left end) position. If I move the Rudder stick, tail rob will move in both direction, but will stop before either end of each direction.

Anyway, I have so many problem with this particular 3G system now, I really fed up with it, and I am planing to get new one. The question is weather I should trust Align again to buy a identical one, or go for BeastX.

Thanks

Rui

[Mslater]

BeastX all day every day !

Best of luck.

Did you default the TX before setting up 3G!
