13 p2. Tossing the ideal up about a second prop. Wat i have discovered is i on run WOT maybe once or twice a trip. I tend to hang around 55 to 60 mph. Looking for maybe more mid range performance. Props are so expensive to be gambling on "this is the right prop". The fury 4 i think is out. My conclusion is either a trophy or bravo 1 either a xs or fs who knows? Problem is pitches. Wat pitch in these 4 blades. Not wanting to play the chasing game. Currently running a 25 fury 3 blade at 5650 to 5700 rpm.
