Product overview
The STEAM AK4215 is a 25T M2.5 breakaway servo arm dedicated to tail-lock servos, with fitment for medium and standard 25T servos. Its body is fully CNC-machined from 6061T6 aluminium alloy and provides freely adjustable angular positioning. The body can be used either way round, making the metal inner ring easier to lock. Mounting-hole distances are 10/14mm, and installation requires an AK4220 ball joint with an M2.5 thread.
A replaceable breakaway gear ring is built into the arm to protect metal rotor-head components and servo gears during an impact. The metal arm maintains servo response speed while incorporating this replaceable element. The supplied set contains one 25T standard tail-lock servo arm, one 25T servo-arm inner ring, one M2.5×7mm socket-head cap screw and one 25T breakaway gear ring.
