F4 continues to evolve the design of the kitefoil with new fuselage and wing mounting design. This design enables angle of attack to be adjusted on both the front and rear wings while maintaing a solid connection to the fuselage. This is achieved by a patent pending internal wing ferrule fitting.
F4 is taking orders while we work through the initial prototypes and design validation process. With composite materials, often it takes several parts to sort out manufacturing issues.
