Not too far from me it seems. The last storm we had blew some bills over into my back yard.

Ok, so I got this thing inside my head that's driving me nuts. I have a M.Troniks ESC (Sorry Patrick, I know this is Castle's section) the truck one and it came with 3 diodes to add to each phase and then it went to the negative battery connector. Now what are they really for?

From the way they are hooked up (cathode to ground), they look like they would clamp the EMF spikes to whatever they are rated for. I would assume they are similar to the TVS devices in operation, except on the motor wires instead of the power input. Another possibility is to add/supplement the built-in diodes in the FETs (older FETs may not have the diode integrated, I dunno).
