I have heard many really great things about these props, but I want to hear your opinions for those who have used them. I am looking at using a 140DZ with an 19x8. I have heard that a bolly turns more rpms than an apc, but does that mean more thrust and less load than an APC, or just more rpms and less efficient. I know Seanychen on this forum has reported 10000+ rpm with a 19x6 on a 140DZ, but that is just way too much for this engine. Would a 19x8 be more appropriate or something bigger. Again no experience with Bolly.

So bottom line my question is does a Bolly give more thrust over an APC? Does a bolly of the same size make the same or more thrust at the higher rpm, and if you have experience with a 140DZ, what would be your guess as to a good performing Bolly. The ideal RPM's for the engine are 8000-8500. Thanks.

Adam
