Spektrum A347 13g Sub-Micro Digital Metal Gear Servo
The Spektrum A347 packs digital precision and metal-gear durability into a 13-gram sub-micro package built for RC aircraft. With 41.6 oz-in of torque and a quick 0.11 sec/60° transit speed, it delivers crisp, accurate control-surface response for park flyers, small foam warbirds, and lightweight sport planes where every gram counts. Mounting screws are included, so it's ready to drop into your next build or replace a worn-out servo.
Key Features
- Digital servo circuitry for precise centering, tight holding power, and repeatable control-surface positioning
- Durable metal gear train that stands up to flutter, hard landings, and repeated loads far better than plastic gears
- 41.6 oz-in (3.0 kg-cm) of torque, strong output for its sub-micro size class
- Fast 0.11 sec/60° transit speed for responsive aileron, elevator, and rudder control
- Ultra-light 13g weight keeps your aircraft's all-up weight and balance in check
- Wide 4.8V–6.0V operating range for compatibility with most receivers and BEC setups
- 40-tooth output spline
- 4.33 in (110 mm) lead for flexible routing through wings and fuselages
- Includes self-tapping mounting screws and a machine screw for the servo horn

Tech Note: The source data lists speed and torque as single values without specifying the test voltage. Performance may vary across the 4.8V–6.0V operating range, so confirm your receiver or BEC output falls within that window before installing.
