The Delta 4 offers the largest performance gain we have yet seen with the Delta model range whilst retaining the comfort and ease of use that has made this series the best-selling sport class wing of all time. Intuitive and efficient AoA control, an improved airfoil design, and optimized internal structure make the D4 an XC glide machine in turbulence. Its structure is the strongest Ozone has yet made. Even in aggressive turbulence the profile remains undisturbed, retaining its shape and efficiency without performance loss from chordwise deformation.
The Delta 4 is for intermediate to advanced pilots who fly 70-100 hours per year and have SIV experience. Due to its ease of use and high levels of passive safety, it is also very suitable for pilots moving up from the category below. More experienced pilots who want to fly with higher margins of safety will find the D4 a satisfying XC tool with class-leading performance.
