Precision SBUS2 Micro Servo for Lightweight Gliders

The Futaba FUSAG300 is a micro servo aimed at F3K hand-launched and thermal sailplanes, with SBUS2 support and a narrow 8mm case profile. Notable published values are 10.8g weight, 0.065 sec speed, and 2.5kg torque at 7.4V, which help when selecting a servo for small control areas and tight linkage geometries.

The SBUS2 interface reduces cabling complexity and may provide position feedback with compatible Futaba receivers or flight controllers. The thin case assists with low-drag installations and tight trays, so double-check tray depth and mounting tab alignment when replacing an original servo.

Fitment tips: ensure spline compatibility with your horns, set mechanical centre before locking in, and confirm the 8mm thickness clears covers and rods. For best behaviour set endpoints and subtrim on the transmitter or receiver and favour soft linkages to lower flutter risk.

Well suited to pilots seeking a small-profile SBUS2 servo with quick response for light sailplanes; always confirm mechanical fit and control geometry prior to final installation.

How should I approach neutral and end point setup for smooth handling?

Start by establishing mechanical neutral, then use transmitter subtrim and endpoint settings to fine tune. Small adjustments prevent binding and keep throws predictable on delicate surfaces.

Will SBUS2 telemetry affect flight controller configuration?

If your flight controller supports SBUS2 messages you can enable positional feedback; check your controller documentation and firmware to map the servo telemetry correctly.

Any advice for avoiding interference in tight fuselage installs?

Plan cable routing to keep the SBUS2 lead clear of moving parts, secure the servo with appropriate fixings, and verify there is no contact between the case and internal structure during full control travel.

Can I rely on the published speed and torque figures for setup decisions?

Use the published 0.065 sec speed and 2.5kg @ 7.4V torque as a baseline, but bear in mind actual performance will vary with supply voltage, linkage losses and mechanical loading.
