So I bought a new tank and same problem. When the plane is running level its good but as soon as I point the nose down I can see air bubles in the fuel line then it dies. This is with a 1/3 of a tank fuel. When its full its fine. Basicly I can fly for half a tank and I better land or if the tank get to 1/3 any pointing down with my plane it will starve
Well of course with only 1/3 a tank that will happen,,
In the air, as you "Dive" typically you'll back off the throttle and run off the fuel in the line, also positive "G"s help hold the fuel toward the rear of the tank in most maneuvers. So unless you're taking it up a mile high and doing some full throttle dives with it only having 1/3 tank shouldn't be an issue.
What exactly "In the Air" are you doing when it quits?
