Foils

Which foil should I start with?

A foil with a large front wing and stable flight characteristics is best suited for beginners. The ideal foil size for learners is between 2000 and 2500 cm². The length of the fuselage plays a decisive role for an easily controllable flight phase. A

Foil design parameters

The design parameters of a foil include wing area, profile, aspect ratio, fuselage length and mast length. These characteristics influence the lift, stability, maneuverability and speed of the foil.- More surface area - more lift, less surface area -

Low, Mid or High Aspect - which type of foil is right for me?

Low aspect foils have a shorter wingspan and are rounder, allowing maneuverability and lift at lower speeds. Medium aspect ratio foils offer a good balance between lift, speed and maneuverability and are therefore versatile for different conditions.H
