Can anyone give me the realistic cruise speed on a Vortex with a 618? Mine cruises at about 60 mph at 6000 rpm. I have an E gearbox with a 3.0 to 1 ratio. Has a Powerfin Prop. I have a max rpm of 6500 in the air but fly at 6000. At this RPM I burn exactly 5 gph. Just need a ballpark so I know I'm somewhat close.
