25mm CNC Aluminium Folding Arm Joint for Agriculture UAV

A CNC-machined, all-aluminium folding joint for multirotor arms made from 25 mm outer-diameter tube. Its spring-loaded automatic folding mechanism lets the arms fold back for transport, the arrangement used on agricultural spray drones and other large tube-arm frames.

Key features

• Clamps 25 mm OD carbon-fibre tube or 25 mm aluminium rod
• Spring-loaded automatic folding mechanism
• 5° upward arm angle machined in for added flight stability
• Suits four-, six- and eight-arm multirotor frames
• CNC aluminium alloy body, about 100 g per joint

Specifications

• Tube size: 25 mm outer diameter
• Material: CNC aluminium alloy
• Arm angle: 5° upward
• Weight: approx. 100 g
• Quantity: 1 joint

Order one joint per arm — four for a quad, six for a hexa, eight for an octo — and measure your arm tube across the outside, not the inside, before ordering. Because the 5° up-angle is built into the joint, use the same joint on every arm so all motors sit at the same tilt.
