Precision Servo ControlMaximum Durability For Heavy Loads
The Spektrum Aluminum Double Servo Arm 3.0" is engineered from high-strength aircraft grade 7075-T6 CNC aluminum to deliver unbeatable rigidity for demanding high-torque RC applications. Designed with a secure 23T clamping spline, this heavy-duty double servo horn prevents gear slipping under extreme steering loads in giant-scale aircraft and heavy-duty off-road RC vehicles.
Heavy Duty Linkage ControlUncompromising Strength and Precision Fit
Upgrade your steering setup with the Spektrum Aluminum Double Servo Arm 3.0", crafted to handle the intense stresses of high-torque RC steering and push-pull control surface setups. Built from premium CNC-machined 7075-T6 aluminum, this 3.0-inch double-sided servo horn eliminates the flex found in standard plastic arms, ensuring crisp, instant control response. The integrated split-clamp design securely locks onto any 23T spline mount using clamping hardware, virtually eliminating slop and preventing spline stripping during aggressive driving or stunt flying. Featuring multiple pre-tapped M3 mounting locations along both arms, the Spektrum Aluminum Double Servo Arm 3.0" offers versatile linkage positioning tailored for large-scale RC aircraft, monster trucks, and custom builds.
