Having a CEN matrix pro BL project too. Still need some parts for the car but almost complete now.
4s 5000mah lipo, tekno rc motor mount, some china esc (2-7S 120A) while my mamba monster is at repair, and 3000kV L-sized china motor.
Motor/esc testing

No idea how that aircraft esc works on car, i'll see maybe tomorrow if other parts for the car arrives. Same setup with MMM worked on Kyosho Inferno pretty well. Until MMM burned.
