Slim SBUS2 Micro Servo for F3K - Futaba FUSAG300  [FUSAG300]

The Futaba FUSAG300 provides a micro-size form factor for hand-launched and thermal F3K gliders, supporting SBUS2 communication and packing an 8mm slim case. Key figures include a low mass of 10.8g, a transit speed of 0.065 sec, and 2.5kg torque at 7.4V, which are important when choosing servos for small control surfaces.

SBUS2 enables simplified cabling and positional feedback when paired with compatible Futaba receivers or flight controllers. The slim case is useful for minimising internal volume and drag; verify tray depth and mounting tab alignment when swapping units.

Before final install confirm spline fit with your control horns, set mechanical centre, and ensure pushrod clearance. For smooth operation adjust subtrim and travel endpoints in the transmitter or receiver, and consider soft-linkage setups to lessen flutter on thin surfaces.
