The advanced coreless motor design reduces rotational inertia, allowing for quicker acceleration, smoother movement, and improved responsiveness compared to traditional brushed servo motors.
Designed to operate from 4.8V to 8.4V, the MD5301H is fully compatible with modern HV receiver systems, power distribution units, and regulated 2S receiver battery setups.
Delivering up to 374.9 oz-in of torque and transit speeds as fast as 0.06 sec/60°, the MD5301H provides the control authority required for demanding flight conditions and aggressive maneuvering.
Its compact footprint allows installation in applications where space is limited while still delivering performance comparable to many larger servos.
The MD5301H features a 25T output spline, making it compatible with a wide range of aftermarket aluminum servo arms and accessories.
✔ 20cc–35cc Sport Aircraft
✔ Scale Warbirds
✔ RC Jets and EDF Aircraft
✔ Pattern and Precision Aerobatic Models
✔ High-Speed Control Surface Applications
⚠ Primary control surfaces on 50cc and larger giant-scale aircraft where maximum torque and surface authority are required.
To achieve maximum performance from the FrSky MD5301H, operate the servo on a properly regulated 8.4V power system or approved 2S receiver battery setup. When designing your aircraft's power system, account for the servo's peak current demands and ensure your receiver, switches, regulators, and power distribution equipment are appropriately rated for safe operation.
When properly installed, the MD5301H delivers outstanding speed, precision, and reliability for today's high-performance RC aircraft.
