Dubro Long Dual Arm Futaba Servo Arm - DUB3340

The Dubro DUB3340 Long Dual Servo Arm is a replacement and extended-reach servo arm designed for Futaba-spline servos used in RC aircraft applications. Where standard-length arms limit your pushrod geometry or control surface travel, this longer dual arm gives you more mounting hole options and greater mechanical advantage across the throw. It's a straightforward, functional part for builders and repairers working with Futaba-compatible servos in fixed-wing models or other RC aircraft builds.

Key Features

• Longer arm length compared to standard servo arms, providing extended pushrod mounting positions and increased control surface travel options
• Dual-arm design offers mounting holes on both sides of the servo output shaft for flexible linkage routing
• Machined to fit Futaba servo splines for a secure, positive engagement with the output shaft
• Suitable for use with ailerons, elevators, rudders, or throttle linkages where additional arm length is needed
• A direct fitment spare for Dubro-equipped builds or a compatible upgrade for any Futaba-spline servo installation

What's Included

• 1 x Dubro DUB3340 Long Dual Servo Arm (Futaba spline compatible)

What You Need

• Futaba-spline compatible servo to mount the arm onto
• Appropriate servo screws or retaining hardware if not already held by a centre bolt
• Pushrod and clevis hardware to complete the control linkage
