Like SMcD responded it will work just fine but it's a bit big , When I built my B64D I first installed the bigger brother of this ESC inside my car (Sanwa SV-Plus Type-D) but you will need to remove your fan , The Type D is a bit bigger so I was not able to install the fan setup . Now I have installed the SV gen 2 inside my car and it's a much better combo with a separate RX-482 receiver.
Your ESC is nice but does not have any punch control . The type D has this option it is called "Throttle Response" . If it fits please install the fan it's way better overall to have it .
