Cat, the 18x8 prop I am using is a Bambula (wood). The 18x8 is recommended to use for break-in of this engine. However at the rpms I am getting, I am worried about two things - 1) landing to hot at the 2000 rpm and 2) over reving the engine at 10,000 rpm. The rpm's were taken with 2 different tac's.
