11x7 is a lot of prop for a.46 sized engine. That is a prop for a .55 to .61 typically. I run 11x5 and set them a few clicks rich. My timer is set for 5:30 which is overly conservative. By the time I land it is closer to 6:30 or 7:00 actual flying time. Mine are .46Ax as well. I never wanted to have one flame out and I am overly careful to set them and run them to avoid a shut down. I will get it out in the next week or so and fly it and see how they run. I don't think I have flown it since the shut down but I may have.
