New FrSky ACT Servos Are Coming — High Performance Without the High Price Tag

We’re excited to share some early news that’s been generating a lot of buzz behind the scenes: FrSky’s new ACT servo lineup is on the way, and these things are shaping up to be some of the most competitive high-voltage servos we’ve seen in years.

Built for pilots who want serious torque without blowing out the budget, the ACT series sits right in that sweet spot — performance, smart engineering, and excellent value for money.

Why ACT Servos Are Turning Heads

FrSky has packed a surprising amount of engineering into this series, including:

• Metal gears for high durability

• All-aluminium CNC machined protective cases

• 8.4V HV support, unlocking noticeably higher torque and faster response times

• Dual precision ball bearings & high-quality potentiometers for smooth, precise movement

• A wide range of case styles — 53, 54, 57, 58 (tabs), and 52 series — covering aircraft, heli and robotics applications

This is FrSky doubling down on high-end mechanical components rather than just electronics — and it shows.

Highlight: The 5400 Series (S5412H / S5414H / S5415H)

If you haven’t seen the specs yet, the 5400 series is where things get particularly impressive:

At 8.4V, the lineup delivers:

• S5412H: 30 kg·cm torque / 0.05 sec speed

• S5414H: 63 kg·cm torque / 0.08 sec speed

• S5415H: 71 kg·cm torque / 0.10 sec speed

These figures put FrSky right up against well-known premium servo brands — but with pricing that’s significantly more accessible for most pilots.

Where They Fit In

These servos are ideal for:

• Large RC planes (especially the S5414H and S5415H with their high torque)

• High-demand cyclic and tail setups for helicopters

• Robotics applications that need accuracy, repeatability and power

• Precision aircraft needing fast, responsive actuation

• Anyone wanting premium-grade internals without paying boutique-brand prices

With variants across the 52 / 53 / 54 / 57 / 58 series, it’ll be easy to match exactly the right servo to the right installation.

Availability at Hammerhead RC

We’ll be stocking the 54 series range as soon as FrSky releases them with further case styles added over time.
If you're keen to be first in line, keep an eye on our socials and newsletters — or reach out and we’ll add you to the interest list.

Final Thoughts

FrSky’s ACT servos look like a major step forward for pilots wanting premium performance at sensible pricing. The early specs speak for themselves, and we’re excited to bring them to the Australian market as soon as they land.

More updates soon — and trust us, these will be worth the wait.
