The new Knuckle Hub Kit is the latest installment of Rotor Bone multirotor components designed specifically for creating unique body configuration.

Similar to the AnyCopter where components can be modified and assembled easily, but the Knuckle Hub kit also gives you the ability to build up and create a much wider variety of airframe configurations.


The multirotors build using the Knuckle Hubs use the standard FT 13370 Straight Motor Mount.

The Knuckle Hub offers room for holding things like the KK2 board and other FPV gear.

Knuckle H-Quad 370 Kit is available in our online store.

Josh used the Knuckle components to make a T-Copter! The Hub Kit also works with David's camera mount available here!
