Hirobo HI0312003 SRB Scale Washout Assembly  [HI0312003]

SRB scale washout assembly

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, allowing finer cyclic response when adjusting pitch and mixing in scale-model helicopters.

Installation typically involves replacing the existing washout linkage in the SRB head assembly, aligning linkages for neutral travel, and confirming smooth movement through the flight control range. Use standard hobby tools and check for correct ball joint seating and free play before flight.

In tuning, this component affects how cyclic inputs translate to blade pitch across the swashplate, so adjustments to linkage length and collective mix should be done incrementally. The part is described and used strictly as an RC-scale accessory for model helicopters.
