Spektrum DX6i / BR6000s

that happened to me with a dx7,in the middle of a fight it stopped working completly, i was puzzled for ages then traced the fault to a reciever, i thought the reciever was broken, then i rebound it and it worked fine.

Still no fix for this?

No news on that front Im afraid.

Still no news on this? This is taking the p***! Surely Spektrum must be able to sort this out. At this rate I wont be able to compete in my next fight and thats in September!

I thought Id just throw in a few observations here.

I have operated Hydra successfully using the DX6i coupled with NCC-70s and a receiver battery.

At Guildford there was an issue which resulted in the relays fluttering so we didnt run it because we couldnt arm it safely.

This was originally attributed to the leads for the new Roboteq controller we have added. On further inspection, when bound with a DX6 there appears to be no problem.

This got me thinking on the differences between what we had before and what we have now and it seems to be the BEC.

James Baker pointed out to me a previous issue with the DX6 which was along the same lines and he did a product recall to upgrade the voltage regulators:

The Spektrum manual says the voltage should be kept above 4.8V and it could well be that when the robot is operated the voltage regulation on the BEC drops down and causes the receiver to drop its bind.

This comment does not seem to appear in the manual for the DX6 (or at least I cannot find it.

The voltage range for the BR6000 is 4.8V - 6.0V.

I am not putting this forward as a definitive explanation of the problem, just an observation at this stage.

I thought I may do some testing on the feathers using a BEC from Technobots to see if theres any joy with it, but also thought Id throw it into the pot for comments.

I apprecicate your input Andy, but unfortunately that is not the solution to the problem Im afraid.

We tried it with RX battery and BEC, and even measured the current draw of the BR6000 (which is insanely high by the way, 145mA with only a standard S75 servo attached and not moving). Still binding is either working after a few minutes or after a couple of retries, or not working at all.

And still no word from Spektrum about this either?

RE:- The DX6i modelmatch feature.

I found this post whilst wandering the web...

Dated Wed Mar 26, 2008

I received an email from Spektrum support today with answers to the
question I asked

1. Is the BR6000 supported with the DX6i?
Answer - YES

2. Will the ModelMatch feature of the DX6i work with the BR6000?
Answer - NO

Spektrum DX6i / BR6000s

Interesting.

Answer 1, that is very doubtful. Too many complaints in the field tell the opposite.

Answer 2 I can understand since the receiver doesnt send an ID back like dsm2 receivers do.

Where did you find this Woody?

Our supplyers have informed us that spektrum are still working on the problem and have not found a solution yet. I believe it is to do with software on the dx6i.

Dx6 has been discontinued. dx7 is fine with the br6000 if anybody wants a solution.

we will keep you informed.

If you can supply me a DX7 for the price of a DX6i I would have no problem with that at all.

Thank you Woody.

Like I said Leo, it was an observation and may be a freak issue, but it definitely made a huge difference to go from a seperate battery to a BEC.

Out of interest did you measure the voltage because a high current draw (assuming a fixed resistance) may cause a dip in voltage. (Ohms law, if you increase the current with a fixed resistance then a drop in voltage will occur if the voltage regulation isnt up to it)

Again out of interest, what was the voltage of the battery pack?

As this is an easy one to test, I may stick in a 6v voltage regulator and see if it makes any difference to the whole set up with the Roboteq. If it does, its worthy of further investigation, if not then its not worth persuing.

Capacitor mod, putting a 4700 uF capacitor on the power line to make sure you dont get any brief dips below 3.5v that will cause the receiver to reboot.
