Well your going to get alot of different answers on here, flight times, battery charge life, it really helps to know what kinda plane you have, you did mention the engine, an evoloution, so I'm guessing it's a hanger 9 plane. if you feed us a little more we can pin-point any and every possibility that could cause your flooding issue, and give you a reasonable way to test your battery for life expectancy. Oh, and pic's help too if you can, especially the engine setup and plane.
