Engine comes with a reliable internal water pump driven by the serpentine belt works really well keep the engine really cool I’m using it for my future project!
A great model engineering master piece combined the precision mechanical engineering (engine itself) and micro power electronic engineering (electric starter with ESC with glow plug power supply). Not only perform outstandingly and also visually very eye attracting. Even placed on the desk, majority of peoples even my wife just thinking it is a piece of mechanical arts!!!
