look at it this way, the Europeans love torque, while the Asians love High RPMs. I learned that from the Japanese and European dirt bikes of the 70s.
many people use 13 inch props on their OS 60s, so I can understand how the MVVS 77 would like a 14 inch prop. needless to say, that you may say your 77 is in the 80 size category.
I would love to have a MVVS 77, but I allready have more engines than I will fly.
