***NOTICE*** It has come to our attention, that ZTW ESC's are not being shipped from the factory with SimonK firmware, even tho they are advertised as having it. We do not open or alter these ESC's and sell them as we receive them from the factory.
ZTW makes ESCs for some of the best and most popular companies out there. Why pay the extra cost when you can get the same great ESCs in ZTW's own packaging? 2-6s Lipo input, solid SimonK firmware and a 600mHz refresh rate make this one of the best bargains on true quality out there!
