Mamba Monster Repairs

[Xtremespeed]

My case separated today when my sons car hit mine and it pulled 2 of the receiver wires loose from the board. I bought the esc from Mike when they first came out, so obviously I've had it a while, and it's no longer under warranty. My questions are, will Castle fix it, what might it cost, and is it worth fixing? If it's worth it, what's the best way to go about it?
Thanks
