You maybe able to run less oil but I wouldn't do it. The oil does add to the compression some. I have run up to 55% nitro in mine and run 60% in my 115WS engines.
Airraptor,

Thanks for doing that comparison. Great numbers for both engines. As for the 70FZ on the same prop, RCSportflyer did a review and got 9,600 rpm (10.1 lbs thrust) on the APC 14x7 with 30% using the stock muffler. I don't think the YS DZ80 exists, but it would be awesome if they offered it.
