Lever Collar 3 x 7 x 6 Hirobo HI2521010 for RC Helicopters  [HI2521010]

Small Retaining Collar for Model Helicopters

The Hirobo HI2521010 collar is intended as a compact retaining part within general helicopter assemblies. Its nominal 3 x 7 x 6 sizing denotes the approximate dimensions and it is used to hold small control levers and short linkage shafts in place.

To use, slide the collar over the target shaft or lever, position it at the point where axial restraint is required, and secure it using the airframe's chosen fixing method. The collar's function is to locate pivot points and to prevent unwanted axial drift in the control system.

From a durability and maintenance perspective, the collar helps keep linkages correctly spaced and reduces endplay, aiding consistent control feel. After fitting, always verify that linkages move freely through their full range to prevent wear and binding.
