To help the belt be as smooth as possible a good shot of silicone spray coating to the whole thing a couple times a season will help it and help minimize static. Kevin Feil suggested this to me and I've been doing it ever since. Spray the belt that is exposed at the rear of the boom and turn the main rotor by hand to cover it all and make sure you get the teeth and the back side of the belt. Soak up the excess with a rag and then hang the heli upright to let any more excess drip down.
Also, Matt has noted before that the heli is actually already grounded due to the metal belt pulleys which then to touch the carbon frame. Plus the metal pulleys will help eliminate static since plastic ones rubbing the belt tend to build up more static in the first place.
