Never thought the day would come when hobbypartz seemed expensive . I just got back from a vacation and got my package on ebay which I had won last week.

I can vouch this ESC is exactly equivalent to the xerun 120A sensored HW.

There are some differences though. The cap module is heatshrunk and layout is different (capacity of the caps seems same size wise). All wires are pre soldered (this is a bad thing for me since I like laying custom wiring and now have to splice and all). And all wires are 14GA while the HW comes with 12GA. Other than that the hardware version is exactly same as the 120A HW i.e. HW247_v1.0 which itself is no slouch as is.

So this might be the deal of the century super happy with my purchase
