Hey guys I got a os 120ax on my phoenix edge 540 had a 16x6 prop thinking of trying a 16x8..anyone have same motor an what prop u like

The APC 16x8 is best for a sport plane. You could also try a Xoar 17x6 wood prop.

16x6 is the best prop to use on a 120AX if your running a pipe.

Well I had the 16x6 an that thing would scream an when landing it comes in pretty fast an hard to land whitch could be me but idk.. I was gonna g8ve the 16x8 a try today.. I get about 8500 rpm with the 16x8 an I get a out 9400 wits the 16x6 motor has a Pitts pipe
