The Airush Ultra V4 uses Brainchild construction technology for a lighter, more responsive big air kite. It delivers impressive hangtime and boost while remaining accessible to intermediate riders.
Best for: Big air riders wanting Brainchild performance at a 3-strut weight
Review verdict
A light-wind foiling weapon that practically refuses to backstall.
4.0/ 5 review synthesis
Strength: Extremely resistant to backstalling — catches itself high in the window rather than dropping
Tradeoff: Pulley bridle dampens kite response, reducing the quick burst and direct feel some riders prefer

4.0/ 5.0
The Airush Ultra V4 is a single-strut big air and freeride kite built around a stiff exoskeleton frame and pulley bridle system that makes it remarkably stable and forgiving. Its standout trait is a near-refusal to backstall, catching itself high in the window and recovering cleanly — a genuine advantage for foilers in light or gusty conditions. The pulley bridle does dampen response slightly, which may frustrate riders used to snappy, direct kite feel.
Pros
- +Extremely resistant to backstalling — catches itself high in the window rather than dropping
- +Single-strut design with stiff exo-frame performs reliably across a wide range of conditions
- +Pulley bridle system smooths out depower and maintains steering feel at the top end
- +Swept-back wingtips aid relaunch, making it approachable for less experienced riders
- +Excellent light-wind foiling tool — the 9m covers a broad usable range
- +Minimalist bag design with easy bar storage
Cons
- −Pulley bridle dampens kite response, reducing the quick burst and direct feel some riders prefer
- −Bag has no dedicated pump storage — a minor but recurring annoyance
- −Only one reviewer session on record; longer-term durability of Brainchild construction unconfirmed
Best for
Foilers and freeride riders who want a forgiving, versatile single-strut kite that excels in light wind and punishes mistakes less than traditional designs.
Not for
Riders who prioritize snappy, direct bar feedback and explosive power delivery over smooth, dampened response.

FORCE KiteboardingReview takeaway
Chilly Graves of FORCE Kiteboarding rode the 9m Ultra V4 for the first time in 11–16 mph conditions on a foil. His biggest takeaway was the kite's near-total resistance to backstalling, recovering itself high in the window instead of dropping — a clear foiling advantage. He noted the pulley bridle dampens direct response compared to what he's used to, but overall called it an ideal light-wind foiling kite for a wide range of riders.
