I use a small length of silicone fuel tubing on the tail support. Cut a piece longer than the tail support - slide it up onto the flared and of the tail support to hold it in place. Then cut the tubing about 1/8 to 1/4" longer than the tail support so it sits on the soft tubing.
I found this very helpful when I was first learning to hover. It gives a little cushion and bounce when you set it down on a hard surface. It also keeps it from skittering over hard surfaces when you lift off.
