Quark fried, blown capacitor...

[jhautz]

Its still the only brushless ESC that advertises itself as "waterproof". I had one for a time that I used as a winter snow bashing esc. Actually didn't use it much though. Turns out when there is snow on the ground...its dang cold outside:019: and that kinda takes the fun out of it.:005:

It was solid for 12 cells and a 9L that I used it with. I never thermalled it (of course it was 20 degreees F outside :p ) Even had lipo cut off for up to 4s. Not really that bad, just not enough voltage and current handling for my tastes.
