Futaba FUSAG300 SBUS2 Micro Servo, 8mm Slim Case for F3K Gliders  [FUSAG300]

The Futaba FUSAG300 is a micro servo aimed at F3K hand-launched and thermal gliders, offering SBUS2 compatibility and a narrow 8mm case profile. Published values include a 10.8g weight, 0.065 sec transit speed, and 2.5kg torque at 7.4V, useful benchmarks when matching a servo to small control surfaces.

Its SBUS2 link simplifies wiring and can provide position feedback on supporting Futaba receivers or flight controllers. The slim body helps packaging in slender fuselages, but verify the tray and mounting tabs to ensure correct fitment when upgrading from stock servos.

Installation advice: confirm horn spline match, set neutral mechanically then fine tune with subtrim, and keep an eye on pushrod clearance with the 8mm case. For reliable control use endpoint limits and consider compliant linkages to mitigate flutter on thin sections.
