Folding Arm Mechanisms
Six machined mechanisms for folding or breaking down a multirotor arm, each with a different locking method. Every type is made in tube diameters from 20 to 50 mm, to your arm length and mounting pattern.
- Six types, each with a different locking method — pick the one that suits your fold cycle and payload
- Positive mechanical lock on every type, none relying on friction alone
- Tube diameters from 20 to 50 mm across the range, others machined to order
- Machined from 6061-T6 billet, hard anodised
- Serviceable — hinge pin and lock replaceable in the field
Choose a mechanism
Folds vertically on a machined linkage against a flat mounting plate. The linkage carries the load away from the hinge pin, which suits heavier arms and repeated cycling.
