Track time with the monster

Well if we are guessing what it is......I would say its a V3 and that the component is the TVS that is located next to the inductor. :)

sorry everyone, wasnt real specific earlier. its a v3 and yes it is the small rectangular componet between the coil and the edge of the pcb.

AH YES, that is the TVS -- or Transient Voltage Suppressor.

That is a sacrificial part that will shut down the BEC output if the voltage exceeds about 7.5V out on the BEC. (That's a new part on the V3 -- and it's a little fragile where it is mounted. We are moving it slightly on the next revision of the control board. And no, that DOESN'T mean there is a V4 MMM (internally, we are on rev H on the MMM I think....)

So -- not something that is required for normal running, but would be nice to have on the board if the BEC shorted out.

Contact me, and we'll get it fixed up for you.

WOW, again Patrick thanks. i dont know what else to say. not really sure what happened, but here is a picture of the happiest girl on earth at the "track" withy "daddy car"

That's only because you know what the V3 internals look like.

...And being an employee (engineer?) has nothing to do with it.

Yeah, Mike is our head Engineering Tech. No wonder..

Good, so who is your reflow soldering QC engineer? You should have a good talk to him.
I inspected two V2s and found A LOT of small solder balls ALL OVER THE PCB BOARD, some even locate between IC pins. The solder balls are held in place by either the solder resin or the protective film later applied on the board after soldering.
