Five33 LightSwitch V2 Ultra Race Frame Kit

The Five33 LightSwitch V2 Ultra is a sub-50g 5-inch racing frame built around Five33's LightSwitch V2 Spine System, refined from the original LightSwitch V2 to shave weight while keeping the same stiffness competitive pilots rely on for tight, technical race tracks.

Key features

• Weighs around 49g bare, keeping the frame well under typical racing weight limits.
• T700 carbon top, mid and bottom plates plus two longitudinal stiffeners give a rigid airframe despite the low weight.
• Five 5mm-thick LS V2 Ultra arms fit every 20x20mm ESC stack, including slim designs such as the Foxeer Slim.
• Titanium screws and aluminium standoffs keep the hardware light without sacrificing strength.
• Includes a 3D-printed camera mount, antenna mount and turtle fin for a complete build.
