Problems Spektrum 6100E on Gau 100

[scallybert]

Actually I had a similar problem, so I spoke to Horizon UK service dept yesterday. Try this.

Make sure everything is off, Tx off and no power is connected on Heli.

Turn Tx on then connect Heli Rx. Light should be solid.

Turn off Rx leave Tx on, reconnect Rx and it will be flashing but servos etc all works fine.

You've just provoked a 'quick connect', by simulating a power failure. That's what the flashing LEDs signify.

Call Horizon Hobby UK and they will explain it better but basically its not a fault. Its to do with the Rx sensing the signal being interrrupted. So if your light on the Rx is solid when you start the flight and when you land its flashing then you've had a problem with power or signal reception. Check with Horizon for exact explanation.

I didn't thnk this happened with an interrupted signal, just if the Rx re-inits, and find the Tx still on the same frequencies as before the init.

The flashing LED can definitely be caused by a power failure/brown-out.

But it can be caused by anything else that causes the Rx to init. In my experience static can cause that.

Another pointer is if the LED flash pattern isn't what you'd expect.

After a quick connect (QC), the flashing LED pattern is regular.

After a static strike, you *can* get an erratic LED flash pattern (on a 6200, sometimes one LED flashes, the other doesn't.) Or you might get an erratic flash patterm followed by a QC pattern, when the Rx calms down.

So:

A static discharge can give effects just like a power problem;

It can also give unusual LED behaviour.

You could try using some MR sheen temporarily on the belt before you get the graphite spray.

In my case it was a repeatable occurance over a few models without being flown so its a feature lol, not a fault or poor power supply. Also I tested this with fresh charged Lipo's.

I checked this with Horizon and it was verified as not a fault.

All I'm saying to the op it try the power off then power on in right order see if lights are solid then cycle the power on the Rx without turning off Tx and see if lights flash and servos move ok.

Worth a shot is it not?

I always use Mr Sheen on the tail and to date not had a problem with my AR6100 on a 450s

Do make sure its the one with 'Static Gaurd' on the can. The normal Mr Sheen will simply make a nice mess

It won't do any harm, and will verify that he has a QC Rx (v1.6 or later, IIRC). It will also show what the QC LED pattern looks like.

Not sure it helps particularly, though ?

What's awkward about static is that the symptons can be really inconsistent and intermittent, and look like other problems.

You can spend a lot of time and money swapping bits around, seeming to fix things - then having it all go wrong again.

Since the various static cures (graphite paste, Mr Sheene, whatever) are quick, cheap & simple, it's the first thing to eliminate.

[Dashik]

Because if he can replicate the problem this way then its unlikely to be static. Why go looking for a problem that may not be there?

Be interesting to see if OP has tried this.

Right all..

Thanks again for all the comments and help from everyone..

After trying most things to try and eliminate them out of the equation.. I have come to the conclusion that it was the static build up, which inturn gave me flashing leds, and the 'brown outs'

Looked around for some graphite grease.. but couldn't find any.. unless I went off to a bearing place.. and I did not have 'Mr Sheen' in my house, and only had a can of Pledge

I decided that I would use some silicone spray. This was sprayed over the belt, and onto the main gear where the tail belt runs.

I have now hovered and flown some very small circuits with 2 complete packs, keeping an eye on the LED... and it has managed to stay on. Complete contrast to before where it would probably not even manage a minutes flight without it starting to flash!

Feeling a bit more confident with it now..


Cheers everyone for the help

i cant believe that its static, because surely 35mhz is going to be more susceptible to it and my 200 worked great on 35mhz.

theres rarely a day that goes by that i dont justify going futaba Fasst... today is no different!

I don't agree with your logic.

Simulate a brown-out, and you'd expect the Rx to behave like it had seen one.

What's important is understanding why it's behaving like that, and a power interruption is categorically not the only way of getting that symptom.

Anyway, he also had lock-outs. What's really interesting is what the LED is doing during the lock-out.

I was close to bench running my SE Pro with data-loggers attached (I'd already had ammeters on the LiPo and a DVM across the Rx power lines, and seen no sign of a power problem while getting lock-outs and flashing LEDs), when fixing the static fixed the problem. Which is why I strongly believe mine was static.

I'd trust this more than silicon polish.

I'd trust this more than silicon polish.

Actually it was a silicone lubricant spray which I bought down the car accessories shop. Use it on the black plastics on the motorbike.. to give it the 'new look'

Will get some graphite paste.. later, but for the meantime, it is fine.

Hi Ade..
Didn't believe it could be static aswell, as I have never had any problems on my other belt driven helis on 2.4ghz

but from trying to deduce what it could have been, nothing else worked. Changing speed controllers, receivers, running the receiver from another power source etc..

All of the above, the receiver would flash after being run up for maybe half a minute.. to a minute.

Only when I lubed up the belt it seems to have cured it.. What else could it have been?


Anyways.. glad it's cured

i cant believe that its static, because surely 35mhz is going to be more susceptible to it and my 200 worked great on 35mhz.

I can see that 35MHz would be more affected by static interference, but IME the Spektrum Rxs get 'zapped' by the static.

Ie a static hit makes them 'crash', or re-init. (The Spartan FAQ #28 refers to a similar effect on the DS760.)

This can look like a brown-out, or in worse cases the Rx has a fit for some seconds before re-initing. In either case, a QC Rx will show a QC has occurred by flashing its LED.

Sounds like 'Spektrum Envy' to me...
