SRB Swash Base Plate Upgrade for SRB Helicopters - HI0302008 by Hirobo  [HI0302008]

Swash Base Plate Function and Fit

The Hirobo HI0302008 SRB Swash Base Plate Assembly is a purpose-made replacement part for SRB-series swashplate assemblies. It provides the lower mounting surface under the swash assembly and secures linkage anchor points for cyclic control.

Functionally, this component positions and supports the lower interface of the swashplate, helping to sustain correct alignment between the swash and rotor head components. Proper installation and clamping of the base plate minimise slack in servo linkages and improve overall cyclic responsiveness.

Installation advice: ensure mating surfaces are free of debris and align the swash assembly before tightening fasteners. Confirm full free movement of linkage ball ends and use proper thread engagement. Perform a control sweep after installation to check for any binding or irregular motion.

Role in maintenance and tuning: as a serviceable item, the base plate can affect pitch control feel. Inspect it periodically for wear, keep fasteners secure, and validate servo horn and linkage geometry to reduce play in the control system.
