When I first got the Revo from Terry, he told me that I should keep the fins where they’re at because he had explored with them a load already. His placement is 1 and a 1/4 inch back from the front of the boxes. for the sides with the center fin 1 and 3/4 inch back.
Not that I am doubting Terry, but since I needed to take the fins out for some glasswork (reattachment of the belt) I figured I’d play with them here and there to see what differences I get out of the boat. Starting out I’m drawing on a ruler to the fin boxes to keep a good account of where the fins are at and how the boat is feeling.
So again currently;
side fins 1 and a 1/4 inch from the front
center fin 1 and 3/4 inch from the front
using the Plastic Australian fins
