Mike had a car LVC in his store. Not sure if he still does or not. You have to pay attention to how the LVC works. If it is a plane LVC, when it kicks in it may just throw you into full reverse.... which would be a bad thing.
You need to find one that will put the car controller to neutral position.
If that is the 70A BK controller you might want to think about adding a fan on the heatsink. Its on the small side for 1/8 applications.
