There really is no reason to empty it out as far as I know. There's no moisture issues like glow and if you plug up your vent you can rotate the plane in any position when transporting it from your vehicle to the house.

Hmm never thought about the moisture issue..I dont really need to turn the plane upside down or anything when transporting so I guess I can leave whatever gas is left at the end of the day in the tank..Thanks!!
