I've read someone here had a fuel leak on the pre mounted Pilot-RC fuel tank. So, I've checked for the leak prior to flying. We had about 20 or so good flights. But, something went wrong couple of days ago. We've gotten consistent 15min flights with some fuel to spare. But, on 10th min, during a low harrier, it died. I thought perhaps something wrong with the engine (which also never missed a beat), but upon opening the hatch, there were fuel residue and the tank was empty.

Upon, closer inspection, there were bits of stopper inside the tank. As the picture shows, the stopper completely deteriorated. I would suggest you stop flying with the tank and replace the stopper with maybe a sullivan stopper for the time being.
