You can adjust the amount of gum used. Make the gum into 3mm balls and add into the diff one by one until you think it is tight enough. I will put some kyosho diff grease together to make the diff smoother. The pros of using gum instead of silicon oil in a unsealed gear diff is that the diff will not loose easily.
