Funny, I just added a 2200mfd 35v capacitior to my V2 last night. The easy way to do it is just take the battery leads and solder it to the sides of the bullet connectors on the battery lead wires right where they plug into the 6.5mm sockets on the board. Thats as close as you can get them without actually soldering on the board and voiding the warranty.

I'll try and remmeber to take some pictures tonight.

any pictures yet

I still think you had a weak fet in there and you gave it a decent workout and it let go. There are going to be some fet issues, just a fact. If the MMMs were not having widespread bec failures, the few smoked escs would just be chalked up to having a few dud components.

The battery excuse is crap, all you did was give the esc a workout and it let go. I did the same thing to a MM once on 5s. I have a 7xl in a buggy geared for around 40mph. I decided that I would try 5s and did not gear down. I got a rock stuck in the spur and the esc fried. I had griffinru look at it and he seemed to think that a section of solder got too hot and bridged 2 phases on the board. He seemed to think that there was a bit too much solder on there. So a rock and some sloppy solder work caused mine to fail, but it was probably getting quite hot from the overgeared setup too. A collection of things were at fault.

I think I have as much time in putting this together as the last buggy kit I put together.

Mods (all within warranty I hope) : Fan hole cut out in case, case bottom has hole cut so the fan plug and coil dont hit, extra thick foam servo tape on the bottom to help cushion it from shock, external BEC wired on, extra 2200mfd cap added.

I havent even plugged this on in yet. I will run the last V1 I have until it fails and then put this in. If this one fails I am giving up on the MMM. There is nothing left to do to it within warranty.

It looks like FrankenESC....
