Abstract: A starting module assembly of a remote control car includes an engine mount and a starter. A seat cover and a fixed base are installed outside the engine mount. A transmission gear cylinder is installed between assembling holes of the seat cover and the fixed base. An actuation gear is engaged between two transmission gear cylinders and sheathed into a spindle bearing of the engine mount for switching the direction of directly installing the engine mount. The starter has a penetrating ventilation hole at the front end of the upper half portion for dissipating heat produced by the electric motor. An external cover for fixing the rechargeable battery is pivotally coupled for preventing the external cover from being separated or fallen off when the cover is lifted. Further, a space is reserved at the front end of the upper half portion for installing an electric motor of different sizes.
