I was reading the posts reguarding installing the G23 (pages 52 and 53 of this post) and it got me thinking. Milton, the guy who owns the plane said the g23 will spin a 16x8 APC at 8550 rpms. However a YS 110fz spins the same prop over 9000 rpm (up to 9700 in some posts). If this is truly the case and considering that the g23 was over 2lbs and the YS is considerably less then that the preformance of the YS must me increable. Anyways, just my thoughts
