Using these RadioMaster TX16S MKII Leather Side Grips is easy. Just attach them to the sides of your RadioMaster TX16S MKII Radio Transmitter. They are designed to fit perfectly, so you don't have to worry about them falling off. When using, make sure your hands are clean to avoid staining the leather. For maintenance, use a soft, dry cloth to wipe the grips regularly. Avoid getting them wet or exposing them to harsh chemicals, as this can damage the leather. If they get dirty, you can use a mild leather cleaner, but test it on a small, hidden area first to make sure it doesn't discolor the leather. With proper care, these grips will last a long time and keep your transmitter looking great.
