Starboard's iQFoil project and their race foil is what made foiling in the Olympics a possibility. You can easily increase control in high winds or increase power in light winds with the six angled spacers that come with the fuselages. The tail wing has -2 degrees built in and you can further adjust the angle by adding the following spacers: -2° / -1.5° / -1° / -0.5° / 0° / +0.5 / +1°. The recommended tail wing angle on the 115 Plus is -2°, so we recommend starting with the 0° spacer. You can reduce tail wing angle up to 2 more degrees by using the -2° spacer, for more speed and control, or increase by up to 1° by using the +1° spacer, for more power.
