Futaba FUSHORN-K Heavy Duty Type-K Servo T-Arm D6mm 3pcs  [FUSHORN-K]

Type-K T-Arm: Purpose and Use

The Futaba FUSHORN-K Type-K T-arm serves as a compact servo horn compatible with Futaba standard splined servos. It is a heavy-duty T-arm marked D6mm and comes as a 3 pcs pack without screws. Ideal where a short T-arm is required to transfer motion from the servo to steering or control surfaces.

Fitment pointers: verify the spline engagement before final clamping and run the servo through its full range to ensure no binding occurs. Since screws are not supplied, pick the appropriate thread and length for your servo case as specified by the servo maker. When experimenting with horn positions for geometry, mark the centre to maintain consistent alignment between swaps.

Tuning impact: using a T-arm horn changes mechanical leverage which directly influences throw and responsiveness. Altering mounting points or arm lengths adjusts mechanical advantage and can sharpen steering feel or control response without changing servo endpoints.
