How to reinforce a loose drive gear on a YIKONG YK4101 RC crawler?

Recently, while operating the YIKONG YK4101 rc car, I noticed that the drive gear felt rather loose. Particularly when the car was climbing a hill or running at high speed, it would sometimes lose power.

Upon inspection, I discovered that the screws on the gears were loose. Subsequently, I reinforced the mounting of the gears and applied anti-loosening screw adhesive. As a result, the problem has been successfully resolved.
