Just to be sure, all of you who had bad luck without a UAT did you use a header tank?? or just the main tanks, because my point was a "header tank" as opposed to a UAT, not without either. As I just can't see a header tank that is full all of the time causing air bubbles.[sm=confused.gif]

my story is that I have the FTE 500 and have about 20 runs on it, two being flights and I have not had any problems with fuel delivery and my setup is a regular 60 oz tank running to a 10 oz header tank, my flights have been from a fairly rough grass field and I have also done taxi test on the grass field bouncing the heck out of the plane, all without the engine quitting. So I guess I'm trying to see from other experience if I'm playing Russian Rullet or not. Seems to be fairly split but I would like to know if the people with the bad luck were just running off of a main tank or also used a normal header tank?
