Hirobo HI0312003 SRB Head Washout Assembly  [HI0312003]

Product summary for SRB washout

This is an RC-scale accessory intended for SRB series rotorcraft maintenance and setup. The HI0312003 washout assembly provides the mechanical interface that controls washout geometry, enabling improved cyclic behaviour when adjusting pitch and mixing on scale-model helicopters.

Fitting usually involves replacing the existing washout linkage in the SRB head assembly, aligning the linkages for neutral travel, and confirming smooth movement across the control range. Use typical hobby tools and inspect ball joints and linkage play before flight.

From a tuning standpoint, this component alters how cyclic inputs affect blade pitch across the swashplate, so make small, incremental linkage and collective mix adjustments. The item is described solely as an RC-scale accessory for model helicopters.
