FrSky Xact MD5312H Mini Digital HV Coreless Servo
The FrSky Xact MD5312H is a compact, high-voltage digital servo delivering up to 423.6 oz-in (30.5 kg-cm) of torque with a 0.08 sec/60° transit time at 8.4V. Its combination of high torque, fast response, and a narrow 0.59-inch (15 mm) case makes it well suited to demanding RC aircraft installations with limited mounting space.
The MD5312H uses a responsive coreless motor, durable metal gears, dual precision ball bearings, and a potentiometer position sensor. Its fully CNC-machined aluminum case provides strength, protection, and improved heat dissipation.
🚀 Target Applications:
- RC airplanes, gliders, and helicopters with narrow or compact servo mounting configurations
- Control surface installations demanding high torque and fast response within a mini-size bay envelope
Key Features
- Mini-Size Profile: Features a narrow 15 mm case design that simplifies mounting inside tightly constrained structures.
- CNC-Machined Aluminum Case: Rugged, fully machined aluminum shell optimizes thermal dissipation while providing robust physical protection.
- Coreless Motor Design: Delivers fast transit speeds down to 0.08 sec/60° and excellent holding response over demanding flight paths.
- Durable Metal Gears: Heavy-duty metal gear train backed by dual precision ball bearings prevents deflection and slop under high mechanical loads.
- Standard PWM Operation: Operates on conventional PWM servo signals via a standard 1520μs / 50Hz refresh rate framework.
- Universal 25T Spline: Output shaft features a standard 6 mm diameter, 25-tooth (25T) spline matching popular aluminum servo arms.
