Product overview
The STEAM AK4064HL breakaway servo arm is an upgrade component for AK400/420 helicopters fitted with 25T micro servos. Its third-generation design uses injection-molded, high-strength reinforced plastic and provides protection for metal rotor-head components and servo gears during an impact. The package contains four yellow-green 25T arms, supplying this configuration as a four-piece set. Designed for the AK400/420 helicopter application, these arms combine the breakaway design with reinforced plastic construction for use in the servo system.
