14 gallons in the header and 5 gallons in each wing. I could have probably gone a few more gallons in the wings but 29 gallons should be more than sufficient unless you are building a single seater with a big fuel hungry engine.
Oh, one thing I forgot. The forward control cable for the aileron runs just behind the forward spar so you obviously need to cut the foam there so the cable doesn't hit the tank. I had my plane hanging upside down so the elevator hung in the full up position which meant the stick was full back and the aileron cable was in the full forward position. I almost didn't realize that the cable was going to rub against the glass on the tank when I pulled the stick back. Make sure you have clearance with the stick in any position. I also put a vent tube in each tank. I drilled a 1/4" hole at the forward corner of the tank in the bottom and floxed in a piece of aluminum tube that was bent forward on the bottom of the wing. I also made an indention on the back corner of the bottom foam plate and after it was glassed I took out some foam and epoxied in an aluminum fuel tank flange so I could put in a strainer.
