Duotone Front Wing Whizz SLS 2025
Item-no. 42250-3833 · Sizes: 850, 1000, 1200, 1450 cm² · Aspect ratio 8.5
A playful mid-aspect front wing that balances efficient pumping with maneuverability.
The Whizz SLS features a mid-aspect ratio of 8.5 and a straight outline with zero sweep that maximizes lift-to-drag ratio for efficient pumping. Its progressive dihedral shape makes the Whizz feel exceptionally playful and responsive.

A robust airfoil similar to the Glide 2145 pump wing delays stall, letting you kick out of waves at low speeds and keep pumping effectively. Each size is fine-tuned with adjusted thickness and camber for a broad speed range and powerful lift at slow speeds.
For optimal performance, pair the Whizz with the 66cm Alu fuselage, positioned slightly forward in your tracks compared to Carve or Glide wings. For extra playfulness use the shorter 60cm fuselage, or the 74cm for a more controlled ride.
