If the motor is a can type and is the same dimensions then yes it will physically fit BUT…the main difference is the winding of the motors which will be different between airplane motors and car motors. That is why there are airplane motors and then there are car motors. Car motors run at much higher current draw than airplane motors. If you put an airplane motor in a car you will most likely damage it along with your speed control. You can either (A) buy a car motor and ESC, or (B) put the airplane motor in the car and burn it up and then have to buy the car motor anyway and replace the airplane motor and ESC.
