BEC voltage is a little off!
YGE 90lv bec voltage set to 7.4 pumping out 17.4 from both master and slave? Already fried all 4 of my servos hopefully the vbar made it...

Vbar should be able to handle nearly 30v with no problems.

WTF, YGE ?!!?
I have the exact same YGE 90LV v2 that I am going to use in my Gobblin 380 build. I am going to put a BEC Guard on each of the master & slave outputs, but still, it shouldn't be putting out friggin 17+ Volts! Did you try contacting them or your dealer?

Not sure where you get that from
The input voltage range for a Vbar is 3.5 - 8.4V. You can probably get away with a little higher voltage, the manual I think says 9V max, but unless Mikado themselves are miles out with their spec the 17.4 volt that the OP's faulty YGE has supplied will almost certainly have toasted the Vbar. Voltage limit confirmed here (for mini): http://vstabi.info/en/node/441 and here (for standard): http://vstabi.info/en/node/639

I got it directly from Mikado USA. I had a Koby 70 fail and shoot 6s voltages through all my electronics. Everything was fried except for the vbar. The 3.3v voltage regulator inside the vbar can handle quite a bit of voltage. I'm not saying you can FLY on ~30v... just that it won't kill it.

ok, that's good to know. Proof of the pudding will be when the Vbar is powered up again i guess.

After the fire, I sent my vbar into MikadoUSA to have them check it out anyway and it was tested and given a clean bill of health. I don't quite have the all the new electronics to get my bird back in the air yet but I've done some test setups and such with my new DS-14 with the vbar and it works fine.
Lesson learned for me was that I won't be using any ESCs that are just heat shrink protected on my bigger helis anymore. I believe the cause of my fire was a tiny solder ball got inside the ESC and shorted out something near the processor causing a commutation error.

vbar
Well it powers up fine and connects to the computer just like it should doesn't say anything is wrong with it. I don't have everything else hooked up to it yet but looks as if it made it ok!!!
On another note the only thing that still worked on the heli was the ESC despite bec @ 17.49 volts the thing still armed and spooled up fine... weird |
