How do you adjust fin tabs on FCS?\n\n\n\n\n\n\n\nI appreciate your photos and explanation. To my eye, an arrangement that mimics a split keel would better create the effect you mention: \"pressurize the mains\"; more than two fins with roughly identical 'swept back' templates.\n\n\n\n\n\n\n\nLooks like mains and canards are both totally flat inside surface.\n        \n\n\nClick to expand...\n\n\n\n\nSplit keel is a completely different design. The split keel came about by trying to loosen up a keel fish. \n\n\n\nThe twinzer is completely different design. In the video surfer explain what he's feeling. You can see during the turns how it projects him up the wave and how well the board holds in the turns.\n\n\n\n\n\n\n\nTo adjust FCS tabs requires you to make fins. I'll post pictures when I get a chance. Have to work soon."]], "columns": ["post_id", "thread_id", "thread_title", "post_number", "author_username", "post_date", "post_date_iso", "post_body"], "primary_keys": ["post_id"], "primary_key_values": ["220457"], "units": {}, "query_ms": 0.7287400003406219, "license": "Public Domain"}
