Perfect value, quality ok but the description is problematic. I bought this as a 40mm diameter prop with 57mm pitch and ended up with a 57mm diameter unknown pitch prop.This prop is made of high quality plastic, it is a drive dog prop and is a great fit for 28" rc boats or around there. It is a left lay/left hand prop.
It works great on my Aquacraft It is much better than the stock prop and gets my boat up on plane much much faster. The boat also goes faster now than it did with the stock prop. Over all an excellent prop and it is less expensive than the Octura
Another great product from Turnigy!!!
