i got my v2 today, and it is dead

[TruckBasher]

Thanks anyway...

Hope you can isolate the V2 failures...

If the resistor is in line only when the esc is switched off is that going to do damage? So you remove the resistor replug the batteries in and then switch the esc on. I haven't tried this but was thinking about it but I won't now. I can see why it would cause problems if the esc was initialising with the resistor in the way (now that i think about it) but not sure why it would with the esc turned off. I don't know how the MMM works and what the switch is switching so I have no clue really.

If the resistor is inline ONLY when the ESC is switched off, then no, it won't cause a problem.

It will cause some huge voltage spikes (and possibly damage the ESC) if the resistor is inline during initialization...

BUT, to be safe, just don't do it. Just say no to the inline resistor.

Risk of accidentally having the esc on when plugging the battery in would be too high. I was just curious. I noticed too that when I plugged my MMMv1 in for the first time ever there were huge sparks which made me jump but after that, even the next day there were none so I'm not too worried. They must discharge eventually but sparks aren't going to be a problem most of the time anyway.

Thanks for the reply too.

So just to confirm, this is a bad idea?

I've ruined a few deans with sparking on HV setups, with bullets you can do one at a time and be quick though, I can usually get it without a spark.. I was thinking of following Biran's calcs for a no spark resistor though...

Yeah, that's a bad idea. We don't recommend it.

The calculator also is WAY off for charge times -- you don't EVER need to charge a capacitor that slowly. A .1 ohm resistor (yes 1/10 ohm) is enough to keep the spark from happening.

The only thing that suffers from the spark is the connectors.

[tc3_racer_001]

and your nerves

can you tell us how many have been sent out and approx. when us international customers can expect to see them in Mikes hands? thanks for the updates!

And they are cheap enough and simple enouigh to replace when they wear down.

Yeah, and with a resistor, you're missing out on the big manly spark that happens when you plug in a fully charged 6S pack! ARrr r rr arrr arrrrrrrr.

[hoovhartid]

I wish I had known about the spark before I plugged in my (6S) batts the first time.

....scared the ever-living $*** out of me.

The 4S set-up doesn't seem to spark

Sparks only make you look cool if you dont jump like a little girl when it happends.

[bl-is-future]

See i am not up on electronics and how they work but when i heard about a resistor i though why use one of those if castle don't recommend it?
I am running a V1 with no problems to this day.

[GT35R]

Yeah sparks are normally bad, but these sparks mean hi powa goodness is about to be unleashed that will rock your world. And don't forget 'chicks dig sparks'

Ahh, bed time.

Amen!

It also drives fear into the hearts of any nearby nitro-heads

Love it! The 6s spark is half the fun. I can't wait to see what 12s does......

[bl-is-future]

so dont jump like a little girl and you will be fine
