Description CARF-Mephisto Fuel Tank Set Description: This fuel tank set for our Mephisto can carry almost 7 l of fuel. It is light weight and distributes the mass of the fuel right below the waist line of the airplane, essential for good aerobatic performance. The round shape works perfect for the fuel pickup and prevents air bubbles to be caught into the hopper. A standard hopper tank is also included in the set.
