If I use the K80 should I use the bypass or not and should I use the wing tank and fuse tank or just the fuse tank? It kind of worries me a little that the fuse tank doesn't have a bit of a dip in the floor and it's just flat so it doesn't seem to pick up all the fuel. I would really like to use just one tank since I want to build it light, on that note what tail pipe should I run? Thanks for the info!
