i myself run CC pro BEC on T600 esp with 12s set up without problem. Many other fliers i know use CC BEC pro and other CC products on their 12s set up and not a problem either. most of the CC
BEC pro and ESC fail on the first try. I had a 110HV esc failed right out of the box. this was replaced by CC. If they work on the first run, they're good. the bottom line is just test it once and you're good to go.
by the way, the Jive/Jazz caught on fire is not a rare issue either.

I run Castle ESCs in most of my birds and they have worked well. I will however not use their's (or others' BEC because of reported failures. That is the reason I like to use a reciever pack instead. I want to insure the I can maintain control of the heli. If the ESC burns up it's not that big of a deal but if you lose all control it can be very dangerous.
+1. I Use CC ESCs in everything electric that I own. The only part that seemed to fail of natural causes was a very old CC35 where the caps failed, and the BEC started dropping out when motor power was high. It was in a planker and I just landed deadstick. They replaced the ESC for free even though it was many years out of warranty.

More recently I had the HV45 in my 500 come loose and fall into the pinion, cutting through the servo lead to the Rx, and with the signal from the Rx lost, the ESC dropped motor power as it should. Fortunately, I had a CC BEC installed for the radio (the HV45 doesn't have a BEC) and was able to auto the 500 down without a problem, and even though this damage was absolutely me fault, CC replaced the HV45 for free.

On my larger helis I choose to run a separate Rx pack (2S LiPo) unregulated, avoiding any potential regulator issues and keeping the onboard wiring as simple as can be. I let the AR7100R receiver regulate voltage for throttle and tail, and my "switch" is plugging the battery into the Rx.

For my job I build and fly a lot of research UAVs, and we use the small blue CC BEC to condition servo voltage in all of them. I've never had a single failure in several hundred flight hours.

I know there have been failures, and it seems that the most common failure mode is full open - unregulated power to the output. I think this is actually fairly common in switching regulators (look for commercial DC-DC regulators if you want to avoid this, eg. Cincon, Vicor, where over-current protection generally drops output voltage instead of smoking the regulator). There are a number of threads on this and other forums on this topic, but I'm really curious as to the details of all of these. In particular, what input voltage were people using, what servos did they have, etc.

The problem is that all of the monster servos we're putting in our larger helis can draw monster loads when bound, and if, for example, one were to power up the Rx with the blades in the blade holder, the current could easily hit 20 amps or more while the person tried to figure out what they did, and this is going to smoke just about any hobby regulator out there. I'm not saying that this is what people are doing, but I think in many of these cases people may be exceeding the specs of the regulator without knowing it.

Maybe it's worth starting a thread with a table documenting the conditions of all the failures. No way to tell, but maybe some useful information comes out of it.

The problem is not limited to 12s setups, I've read of many 6s cc pro bec failures sending full voltage to the electronics.
Those tech guys must have a pretty hard time keeping a straight face when they tell everybody that they've never heard of such an issue

I've personally had over half a dozen castle esc's fail on me or burn motors up with their hasty firmware updates.
I've had zero issues with the kontronik products, and they perform better too.

I'm going to call CC tomorrow and ask how many failures have been reported for their Pro BEC. Do you think they will tell me...the truth?

FWIW, they are several reports of the Kontronics BEC taking a crap too. It seems the switching BEC's all can fail in the open position. Maybe a linear BEC... nah,

I'll probably go with a 2S A123 pack. I just hate to add extra weight. Although I could place it rearward of the mast and use heavier, higher capacity powertrain packs (12S, 4000mAh) on my 600. Yes/no, anyone?

I just hooked up the CC-BEC PRO on my 12S T-600 last weekend. I used a DVM to measure the voltage after setting it through CC software. At 6V setting my Fluke 87 DVM measured 6.01V. I measured both outputs, the voltage were the same.

As a rule, I always measured the power source voltage before plugging it into any electronics.

I have at least 10 CC ESCs and the BEC-PRO, none of them is giving me any kind of trouble. I guess I am just lucky.

Wow it seems every week i here of this happen, i have read of about 10 failures now.

Wonder how many are out there? The thing is ALL the failures seem to be on 10 or 12S, makes me thing its not capable of running 10/12S reliable.

It should not be hard to incorporate some sort of clamping diode or whatever when the volage get above a certain point it cuts. CC should look into this.

Been running CCBEC's on 2 different 12s birds for some time now.

No problems.

I hear Kontronik Jive are great, but i remember hearing quite a few complaints about he internal BEC browning out and people losing their birds. I don't remember the specifics, but it had something to do with running 6.0 volts on the internal bec instead of 5.6volts i think. It seemed to happen with at least similar frequency (maybe more) than castle pro bec failures assuming the 10 incident number someone stated for castle pro bec failures.

here's one about jive BEC problems:

http://www.helifreak.com/showthread.php?t=183157

And another:

https://rc.runryder.com/helicopter/t555158p1/

and another:

https://rc.runryder.com/helicopter/t553487p1/

Definitely not an isolated incident.

All i'm getting at here is that although i would agree wholeheartedly that the jive is a much better controller, their not without fault either, and many a bird (sadly many a logo) has been lost due to the jive bec problems.

Yeah it had an issue with the BEC @ 6v with 8717 servos....that was pretty much it. Run it @ 5.6 and it was fine (I am currently doing that now ) The BEC never fried all the other electronics. A few had issues for sure but never lost everything (crash and/or lose electronics on top of that).............Ron

No need to run 6V (which is not default), it also gives no extra in-flight performance with modern servos.

bit the bullet

well i bit the bullet and dropped the dime for a Kontronik Jive. Everything else should be here today to get the Logo back in the air. i may be needing a place to stay tho when the wife sees a grand on the credit card

btw - if you see me at Saranac this week end or at IRCHA say hi, but i only paid a couple hundred to fix my heli (wife is coming this year)

Jive issue is resolved in v9 which is out now.

And yes it was only at 6v and only with 8717 servos.
It was actually overvoltage that rebooted the bec for its own protection.

(servo act as generator when moved very fast and when they then stop)

Ive seen more than a few CC bec pro failures this spring, including non fatal ones, where it just screwed up gyros etc

So does V9 BEC funtion as V5 or is it still sensitive but power comes back quickly?

I am running V5 and align servos on 1 heli at 6V
