    Bought from an IW member a few years back and finally got it done.

    CMB 21 Rsv07 with Beta sleeve/piston & SPP NR21

    Runs great, likes a little bit of inside tab down.

    Thanks DT for the setup tips.

    I was surprised that did you put to fit Beta EVO Piston/sleeve into the CMB 21RSV07?

    Thanks guys.

    New rsv07 piston and sleeve were not available so the beta can be fitted with no mods.

    The original tabs have no adjusting bolts so bought a speedmaster set. Should they go together directly over the planing strake or either side of it?

    Cheers

    Thanks Shane, the orange is Valiant Charger E49 vitamin C. Reminds me of one of my first cars I should have kept.

    I would put your rudder on the other side of the bracket, moving it a little further out. Maybe even putting a spacer between and put the transom fin as far to the right as possible, in the corner. We used to have to bend the transom fin vertical to hold the back corner down during hard corners in chop. I liked double plates, inside right would be down, outside right would be up a smidge. Rudder bottom would be rounded and kicked under, better to kick the hinge pin than just the rudder. Finch knows better than me.
