One of our teammates crashed during a Contest, the radio did not respond at all, not even fail safe.

It was either the battery or the switch that failed most likely, any ideas or experiences? I have four Duralite batteries and it is not the first time I hear stories about this.

Any reasonable comment will be appreciated, please do misinterpret my question I don't want to harm the manufacturer, I just looking for a safe way to operate the product or go to other options if it is not safe.

Best regards to all

Did you test the regulator under load? They have been known to fail, especially when brand new. Running them for awhile before the first flight is good insurance.

Regulator, humm, I was thinking on running a cycle with the shure cycle or the Triton to measure "real" capacity, this done with the regulator so I can check both at the same time, on the Triton I will try it also without the regulator but it does not make much sense.

On the other hand, being redundant, who do we know when one pair fails?, unless we run thru a cycle like I just described, I really don't know what else to do.

With all the mone invested in this models and top of the line equipment it is not comfortable to be scared of a failure.

Unfortunately, failure is a risk with all electronic and mechanical parts. I've had regulators fail in the most odd ways....I had one in a helicopter that caused tail and cyclic glitches...it smoked itself while I was testing it on the bench (fortunately). I've actually had better luck with Duralite than I did with Flightpower. I have also used and use Dualsky regulators.....bottom line is anything can fail- welcome to the real world<G>

I´ve talked to the Duralite guys, and it seems I have the wrong battery leads even if I bought it as a kit for a specific setup, and they also recomended me to use the regulator with fail safe sw, also they are going to exchange it for me, that is nice.

On the other hand I looks that discharging the battery to measure the milliamps maight be the only way to detect a bad pair of cellls in the redundant batteries. Of course it must be noted the safe maximun discharge voltage to avoid damaging the batteries.

Redundant systems are more real world systems, Aircraft Electronic Engine Controls are dual channels, and it is very very rare to see an inflight shut down, that does not mean it will happen, same applies to good quality systems in RC.
