HIROBO HI2526002 Compact M3 Thread Stopper 3 x 7 x 5 for Model Helicopters  [HI2526002]

M3 Thread Stopper Description

This M3 stopper serves as a low-profile axial limit device, giving consistent positioning on systems using M3 threaded shafts. It is aimed at model helicopter control assemblies and similar RC setups where a compact stop is required without modifying core hardware.

Compatibility: intended to engage with standard M3 threads or shafts. Check the mating thread and seating clearance on your pushrod, hub, or bracket before installing to ensure proper fit and travel.

Installation and tuning role: screw the stopper in to the desired location and validate movement and contact points during controlled rotations or slow control inputs. Use very small adjustments to establish end-play limits for swashplates, linkages, or rotor parts. Periodic inspection will reveal loosening or wear that can affect handling.

Maintenance notes: maintain clean threads, ensure the stopper does not create binding, and replace if deformation occurs after repeated service.
