Product overview
The Steam H7088 is a tail-lock servo arm for standard 25T servos, with M2.5 mounting-hole distances of 14/18mm. Its fully CNC-machined 6061T6 aluminium-alloy body allows free angular adjustment and can be used in either orientation to facilitate locking the metal inner ring. A replaceable sacrificial gear ring built into the arm helps protect metal rotor-head components and servo gears during impact. The metal arm retains the servo’s response speed.
Compatibility covers most standard 25T servos, including KST BLS815, BLS805X, 515, 725, 815 and 825, plus Futaba 9257, 9254, 3003, BLS257 and BLS254. Additional compatible models include MG995, MG945, MG996, MG946 and S3003. The supplied set contains one 25T standard tail-lock servo arm, one 25T servo-arm inner ring and one 25T sacrificial gear ring. Fasteners comprise one M3×6MM button-head hex-socket screw and one M2.5×10MM socket-head cap screw.
