Interesting, looks like the feigao sensored esc that I saw somewhere, the motors look familiar too.
Looking at the spec, it may even handle 4s with the bec disable. That would be good for the 13.5 novak motor, as it looks like a good 4s motor. I may have to try one out!
I'm happy with my 4S sensored system from HW and I'm having difficulties having them sold here in the US as they make ESC for Speed Passion, Venom and soon Orion. I told them I would make enough changes to the ESC that they would not be like the above mentioned, but the guy from HW still said he doesn't want to loose friendship with Speed Passion. I'll keep trying.
