Propeller options

[spareparts]

i think you can get a 13.25 X 19, don't worry about the diamter too much, just use the pitch numbers to get you in the correct rpm( if you were running more hp at higher speeds it would be more of a concern), if you want to fine tune it you can change diameters, but I don't think you will gain enough to offset the price of propellers. Stay with the same brand of props while you're swapping them, I've seen measured pitches vary by manufactures by a wide margin
