I started flying my combat spad this weekend. Here is the setup... Hybrid spad dog fighter / DPS, OS46LA, 11x5 prop, 15% fuel. Now the problem. This plane flies really nice, BUT when I start a combat style flight... sharp turns, inverted, loops, rolls etc.. the engine dies. Its acts as if its starving for fuel and at times I can recover it if I get it level fast enough for the engine to get fuel. The fuel tank seems to be sealed with no air leaks. The fuel mixture is fine.. couple clicks rich from peak. It will climb vert without lean stall. Does it sound like my fuel pick up is maybe hanging? Is there any special setup tricks for a combat model? I figured this is still a beginner question so I posted here.

Thanks
