Easy.

I think its foolish to cart around an entire gallon of fuel. I mean when have you ever needed that much fuel in one day.
So my solution was simple. I took a 50oz fuel tank and mounted it in a plastic toolbox from walmart. Hooked my fuel pump up to it, installed my power panel flight battery ALL inside. This toolbox serves as my flight box. Plenty of storage inside.
I get 4 flights out of the 50 oz tank. perfect for my typical day of flying. and with out ALL the weight and clunkyness of carting around an entire gallon of fuel. If you want to fly more I just keep the gallon of fuel in my car to refill the 50 oz tank.

Ill post a pic later that shows my setup.
