No problemo jay, What would be the difference in rpms with different diameter props? The 3 blade Laser II I have is a 14 1/4" the High Five is 13 3/4 and the Tempest Plus is 14 5/8". I'm sure there is going to be a difference in rpm, whatcha think? Keep in mind, with the same pitch but changing the diameter the rpm's will change, the smaller will turn more rpms than the larger diameter..
