Product overview
The STEAM H7081 is a 25T frangible M2 metal servo arm for helicopter servo applications. Fully CNC-machined from 6061T6 aluminum alloy, it incorporates a replaceable frangible gear ring that helps protect rotor-head metal components and servo gears during an impact. The metal arm maintains servo response speed, while mounting hole distances of 15mm/18mm/21mm provide three attachment positions. It fits most 25T standard servos, including KST BLS815, BLS805X, 515, 725, 815 and 825.
Compatible Futaba servo examples include 9257, 9254, 3003, BLS257 and BLS254. Other supported models include MG995, MG945, MG996, MG946 and S3003. The arm also accommodates 25T servos from Futaba, savox, Xcore, HL, HSP, HD power and Go tech. The supplied set contains one 25T standard metal servo arm, one M3×6MM button-head hex-socket screw and one 25T frangible gear ring. The replaceable ring forms the sacrificial element within the metal arm assembly.
