That, 48mm, or the 215.

Anyone getting close to the 38mph that Grim recorded on the 12cells? I think it was 36.1mph from Steve using the 642. Maybe we can't get there because of the extra turn fin we all went and put on, but it just doesn't seem possible with the 440/3 prop. I'm asking because no one has yet exclaimed the break through.

Unless there was a steady 5-10mph surface wind to the boats back, or the batts were at just the right time in their charge life.

Sorry 14cell and lipos.......looking for stock 12cell like Grims config.
