Quadifier King Cobra MK-2 - 5" Stretch X Geometry Frame Kit

Quadifier King Cobra MK-2 - 5" Stretch X Geometry Frame Kit

There are frames you fly, and then there are frames that make you stop and stare before you even build them. The King Cobra MK-2 from Quadifier is the latter. This is a frame that was clearly designed by someone who grew up dreaming about what the perfect quad would look like — and then actually built it.

The Stretch X geometry is the defining characteristic of the King Cobra MK-2. By stretching the frame's footprint along the forward axis, Stretch X gives you noticeably more efficient forward flight compared to a standard True-X layout — the quad cuts through the air with less drag, holds speed more naturally, and rewards pilots who fly with momentum. Whether you're pinning throttle down a long straight or flowing through an open field, the geometry works with you instead of against you.

The MK-2 takes everything that made the original King Cobra a head-turner and refines it. The camera bay was expanded to give you more angle options for your nano camera, the strategically placed cutouts throughout the frame reduce weight while reinforcing the structure where it matters, and the super stretch profile gives the whole build a lean, aggressive silhouette that looks as fast as it flies.

The arms are 5mm carbon fiber — thick enough to handle real crashes without flinching — and the frame is designed around 20x20 stacks, keeping your build compact and clean. Two stack height options are available: standard for a traditional build layout, and slammed for a lower center of gravity and razor-sharp flight characteristics. The slammed option is the harder build of the two as it requires everything to fit tightly inside the frame, but the flight reward is worth it for pilots who want that extra edge.

GoPro mounts are available, making the King Cobra MK-2 a capable content creation platform as well. The included TPU nano camera mount and TPU nano lollipop antenna mount round out the kit so you can get straight into building.

An American brand, designed by a pilot who built the frame his inner child always wanted. The King Cobra MK-2 is the result.
