Using this TPU cover is a breeze. Just simply place it over the vulnerable parts of your Radiomaster TX16S or TX16S MKII controller. It's designed to fit snugly, so you don't have to worry about it falling off easily. When you're ready to use your controller, removing the cover is just as easy. As for maintenance, a simple wipe with a clean, dry cloth will do the trick. If it gets dirty, you can use a mild soap and water solution, but make sure to dry it thoroughly before putting it back on the controller. One important thing to note is to avoid using sharp objects near the cover as it may cause scratches or tears. Also, don't expose it to extreme heat or direct sunlight for long periods as this could affect the quality of the TPU material.
