Thats the ESC Utopia has, i think it was one of the first to use the V2s but a few other roboteers have used them since then aswell and given very good reviews.

Apparently some people had problems with using the old ones with Spectrum controllers, however i have no idea if this has been fixed on the V2s or not.
