Hi Mate I suggest that you read all of the threads on Align Flybarless on the Helifreaks site including the sensor mod from leon luke and jonjbear.

best wishes Tony

Sounds like the late bind problem, if possible power up the RX first, let it initialize then power up the 3g to test this.

If it initialises ok like this, search for 3g late bind problem.

hi Tony:

Thanks for your reply.

I have read all thread regarding with flybarless I can possible find, including the one you have suggested, but I still can not find what is wrong with my Align 3G system, that's why I am posting this thread.

However, every time when the 3G system won't initialize, if I plug into computer and do update to v2.1 again (which it already on least V2.1), it would initialize for next few power up (may be 3-4 times) and then the problem will come back again.

Do you have any other suggestions? I am really struggled with with Align 3G system at this moment.

Many thanks again.

Rui

Hi:

Thanks for you reply.

I have just tried your suggestion, but still doesn't work.

Also, I have read about spektrum Rx late bind problem, and tried some other method, including power off the Rx (and keep the Tx power on), and immediately power the Rx back, but it's doesn't seems to solve or defined the problem.

Do you have any other suggestion, I am really suffering this problem at this moment.

Many thanks again.

Rui,

Can you post some close up pics of the installation just in case there's something obvious.

Also, would you detail the power on procedure step by step that you go through and what lights are on/off at each step.

Has it ever initialised since the upgrade ?

Hi Mslater:

Thanks again for you reply.

When I power on:
1. I would power up Tx first;
2. then turn throttle hold on and keep Gyro in Heading Hold mode,
also keep throttle stick at lowest point;
3. I would connect the battery and ESC at last.

After I power up the ESC, all lights on 3G control unit would flash in green three times, then just state light continuously flash red and green alternately.

The 3G system has initialized before and seems every thing work in order (but I never flew, only ground test). When it works, the initialization procedure is exactly the same as the video posted on Youtube by Bert Kammerer. However the initialization is failed at most of time.

Some time the system would initialize after few attempt, but some time just won't work at all, in this case I had redo the update procedure as I mentioned in earlier post, it will works for may be 3-4 times power up, and then the problem would back again.

I am currently using the longer cable that come with the system, but I have also tried the shorter one, the result is the same (P.s I have checked the Pin in both 3G sensor and control unit).

I really can not think of if there is anything else I haven't tried.

Below is the close picture of my setup on Heli, the number 4 is the sensor.

Many thanks for your kindly reply.

I can't help you with your 3G problem but I would make the comment that the sensor is not going to work at it's best on that flimsy plastic shelf. Far better placed up on top of the boom mount. I had all sorts of hassles with my 500 with gyros mounted down there

I know some people seem to get away with it but it wouldn't be my first choice of mounting positions

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.

The status lights indicate a bad connection to the sensor unit or a failed sensor.

More specifically it indicates a bad response from the sensor.

Try doing the firmware update again, it has been known to solve the issue. If not then I suggest a new sensor, or at least a trip to the shop, they should have one you can test with.

Best of luck

Sorry just noticed you had tried this alread "Try doing the firmware update again, it has been known to solve the issue. "

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

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 rebinding 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:

Thanks for you reply, I will try some other method before I go back the "shop", cos I bought this heli from ebay which has been shipped from Taiwan.

**Mslater** · 30-12-2010, 09:42 PM

Rui,

Don't be afraid to walk into your local heli shop and ask them for advice, you will find most shops more than willing to help on the basis that you will support them by buying from them in the future.

Your local shop may be slightly more expensive than buying on-line but they are an essential backbone in the hobby.

Ask for a recommendation in the main discussion forum for a local outlet near you.

Thanks for your suggestions. I will try Tony and Ian's suggestion on above thread (11 and 12) tonight, check all the pin and rebind the Rx to my Tx. I will keep update tomorrow.

Once again, really grateful for you help!

Rui
