Default Main gear replacement Walkera 4#3b

I found a really easy way to replace the main gear pin on the 4#3b. I took a pair of fairly short needle nose pliers and Dremeled a slot on one jaw parallel to the jaw. It keeps the pin from rocking while you hold it with the pliers, and also keeps the pin from sliding backwards into the jaws. Worked like a charm on the first try.
