FrSky Act S5414H Coreless Servo
The FrSky Act S5414H is a high-voltage coreless servo built for demanding RC aircraft applications. Housed in a fully CNC-machined aluminum case with all-metal gears, it delivers the durability and precision required for sport flying, aerobatics, and scale warbirds where reliability and consistent centering under load matter.
The Act series coreless servos utilize a fully CNC machined aluminum protective case and benefit from metal gears. These high-voltage servos are capable of supporting up to 8.4V and offer both high speed and torque performance.
The Act series servos are available in a range of models to support different torque and speed requirements depending on your needs. These servos are ideally matched to models where power, reliability, and precision are required — particularly fixed-wing aircraft with demanding control surface loads or high-vibration environments.
Why We Recommend This
The Act S5414H is FrSky's compact coreless offering — metal gear durability in a smaller form factor, with the torque and speed specs to handle control surfaces on mid-size aircraft without the bulk of the larger Act series. A reliable, no-fuss servo for straightforward builds. FPV Builds RC provides U.S.-based product support and setup guidance for FrSky products purchased through our store.
Frequently Asked Questions:
What is the difference between the FrSky Act and Xact servo series?
The Act series (including the S5414H) is FrSky's performance HV servo line with CNC aluminum cases and metal gears. The Xact series is FrSky's premium tier and adds F.Port 2.0 telemetry capability for in-flight servo health monitoring via the S2F Port 2.0 converter. If servo position and load telemetry on your transmitter isn't a requirement, the Act series delivers excellent performance at a better price.
What voltage range does the S5414H support?
The Act S5414H is an HV (high-voltage) servo rated for 6.0V–8.4V. For maximum torque and speed, run it at 8.4V from a 2S LiPo or an HV BEC. A standard 5V BEC will power it but at reduced performance. Always confirm your BEC output matches the HV requirement before installation.
What torque does the S5414H deliver?
The S5414H is rated in the mid-torque tier of the Act lineup. Exact voltage-curve torque and speed specifications are in the FrSky S5414H datasheet. The coreless motor provides fast, smooth response with minimal dead band for precise surface control.
Which aircraft applications is the S5414H best suited for?
The S5414H is well matched to mid-size fixed-wing sport aircraft, trainers, scale models, and aerobatics planes that need a durable, metal-geared HV servo. The CNC aluminum case handles field use and temperature variation well, making it a dependable choice for aircraft that see regular hard use.
Is the S5414H compatible with non-FrSky receivers?
Yes. Like all Act series servos, the S5414H uses a standard 3-pin PWM connector and works with any receiver that outputs PWM servo signals — FrSky or otherwise. No special FrSky hardware is required for basic operation.
How does the S5414H compare to other Act and Xact servos in the FrSky lineup?
