Good reason for using 2S bec !

[Baldie]

Well, Due to a Bec connected to 6S (was designed for 2-6S input) going bad and passing 22v through, I now have 2 dead DS620s, And a dead Total G, Just being thankful the tail and other 620 escaped, and it wasn't connected to the ESC.

For me, from now on will be sticking to a separate rx pack, So worst case only 7V ish gets through. The small weight penalty is worth it !

Which bec please?

[ModelGuard.Com]

Nasty, what make?

[Baldie]

I would rather not say, as i dont want to spark a big debate about it. But needless to say it was a well known brand, and it has been operating without issue for some time. This happened on the bench fortunately.

But it is something to bare in mind when choosing a power system for larger models.

Was this why you were after some ds 620's mate?

Yep! Got some sorted now

Isn't this why we are here for a good debate. Come on open that can!

But we can't make an informed decision if you keep us in the dark. lol.

or to embarassed that he was using the 5a align bec that came with a kit

Sorry for the mystery. My point is that electronics can fail. I know it's not an issue as I have not read of it happening to others with this bec. It may have been caused by unknown damage in a previous crash. I got the unit second hand and have happily been using it for over 6 months. So from that point there is little point in me mentioning the brand.

Sounds like the Castle BEC Pro v1 which when it dies passes the battery voltage straight through to the electronics, apparently fixed in the v2

Good reason for using 2s bec OR good reason not to use 2nd hand electrics?

Also tell us the make n model or else chinese burn for you.

True. But,

That's ok if it's your kitchen radio or bedside alarm clock. But not so of a piece of leccy that's flying several Kg and ££££s worth of aircraft in supposed safety.

These things are built to a price, weight so I reckon that unless very good they are like most things these days - built-in failure.

Plus, are we really adding too many unessential leccy things in the quest for lightness. I still use a separate Rx pack on some of my helis.

He said designed to run on 2s-6s, that rules out the bec pro as that can run 12s. I reckon its the blue 10amp version
