I plan to take this one to flyinns and I like to have 15minutes of fuel onboard for flyinns. I know that 16 oz of fuel in this g-62 lasts 10 minutes, the provided tank is less than a 16 so I added a second 8 oz tank. that should be enought to fly 8minutes and leave 6 for the clear to land. the tanks are built just like they were the only tank in the plane. i hooked the carb to the clunk in the larger tank, ran the overflow of the larger tank to the clunk of the smaller tank, and the overflow of the smaller tank becomes the overflow. I then mount the smaller tank above the larger and as far forward as posible.
