Futaba FUSHORNA-4 Type-A D6mm Cross-Arm Servo Horns Pack of 4  [FUSHORNA-4]

Type-A D6mm Cross-Arm Horns for Standard Servos

These four Type-A cross-arm servo horns are replacement parts intended for standard Futaba-style spline interfaces, supplied without screws or retail packaging. The items are sold as 4 pcs and match the D6mm cross-arm dimension referenced in the product title.

Use the horns to change linkage geometry or to swap out worn components during routine maintenance. Because screws are not included, retain your existing mounting hardware or buy compatible retaining screws separately. Verify the D6mm cross-arm interface on your servo before installation.

Installation is straightforward: align the horn with the servo spline, seat it fully, and secure with the correct screw for your servo model. These horns act as simple mechanical link points; altering horn type or lever arm length changes throw and mechanical advantage, which helps when tuning steering response or control surface movement on scale RC vehicles.
