I'm back from the field. Tach battery low so no rpm report. But I can say that after a bit of tweaking on the needles for the new prop it was worth the trip.
Roll out was a tiny bit longer it seemed (maybe two feet more) and my speed might have been a touch higher in general. I know I used the throttle down switch on my 9Super for landings. But they were still harrier stops like always.
Hovering was easier than before at half throttle and sustaining the hover was just a blip more of throttle instead of full. So I guess the answer is YES. Try this prop out on your Saito/UCD 46 combo. The best part was how cool the engine was after landing. You could have stuck your tongue on the valve covers.
