EMBLA SZM2 Tail and Cyclic Wash-Out Arm HI0304116 from Hirobo  [HI0304116]

EMBLA SZM2 wash-out control component

This RC-scale wash-out control arm is defined for the EMBLA SZM2 line and is provided under the Hirobo HI0304116 part number. The item serves as the linkage that converts servo commands into measured wash-out movement at both the rotor head and tail linkages, supplied as a direct replacement or spare where EMBLA SZM2 parts are specified.

Installation notes: assess the present linkage geometry before removing the old arm, keep original ball cups and mounting hardware where appropriate, and confirm unobstructed travel after fitting. Fit using the correct hex drivers and check that the arm clears cyclic and tail linkages across collective and cyclic travel. Avoid overtightening fasteners to prevent binding.

Tuning role: minor wear or play in the wash-out arm will alter how cyclic inputs are mixed with tail control; fitting a new arm is a straightforward method to restore consistent wash-out response and reliable tail authority in hover and manoeuvres. Complete gentle hover checks to verify trim and handling before returning to full flight envelope.
