4 of those Maytech MTSESC6.6 vesc based escs are up for sale now too.
The risk is too high that I will build one more mtb with them, so better to not have them laying around 
One phase wires would need a bit of heat shrink or just soldered on new, besides this they are in top shape.
Asking 135$ each
Or 480$ for all 4 together.
