Try the 10.5x4.5 APC its faster than the 9X6. If you are running a 10x6 I don't see how you have engine problems since you aren't turning high RPM. If that's the case you need to understand how to dial a needle valve.
Are you allowed to run the bubble free tanks like the Tetra tanks? that might also be an issue.
