Arrowmax am-449140 Precision Phillips Driver 4.0 x 110mm Tuning Tool  [am-449140]

Precision Tip for Setup Work

This Arrowmax am-449140 Phillips screwdriver is a purpose-made RC-scale maintenance tool sized 4.0 x 110mm and released as a limited edition. The dimensions in the product name describe the Phillips tip size and shaft length, which define the tool's reach and fit for common Phillips-head fasteners used across RC models.

Compatibility is broad by design: the driver matches Phillips screws typically found on servo mounts, motor and pinion assemblies, gearbox covers, and chassis panels. Because it is an RC accessory, avoid implying any full-size vehicle applications; its role is to support model assembly, setup and routine tuning.

Practical use notes: the 110mm shaft offers extra reach for recessed screws and tight compartments, while the 4.0 tip aligns with medium Phillips fasteners used in many touring, buggy and truck platforms. Use steady, axial pressure when turning screws to reduce cam-out and protect screw heads and small components such as servo horns, motor mounts and bearing retainers.

Limited edition markings are primarily cosmetic; evaluate the tool on fit, length and tip engagement when adding it to a workshop kit.
