Arrowmax am-419140 Limited Edition 4.0 x 110mm Hex Driver Allen Key for RC servicing  [am-419140]

Compact limited edition hex driver for setup and repairs

The Arrowmax am-419140 Allen Wrench is a compact, RC-scale hex driver specified as 4.0 x 110mm and released as a limited edition. It is intended for use with standard RC hex screws and fasteners, giving a defined tip size and reach for repeatable adjustments during setup and repair.

Reach and tip consistency help when securing receiver mounts, trimming servo linkages, tightening motor mounts, or making precise on-model tuning changes. The long 110mm shaft provides extra access to deep-set screws while the 4.0mm tip fits the common hex heads used across many models.

Maintenance advice: verify correct tip fit before full torque, clean grit from the bit to protect screw heads, and store the wrench separately from heavy tools to avoid damage. This is a hand tool for RC hobby use only.
