Hirobo HI0304116 Wash-Out Arm for EMBLA SZM2  [HI0304116]

Wash-out arm details for EMBLA SZM2

This RC wash-out control arm is specified for the EMBLA SZM2 range and is listed under Hirobo HI0304116. It provides the linkage that converts servo movement into measured wash-out response at the rotor head and tail linkages, and is supplied as a service spare or replacement for airframes that call out EMBLA SZM2 parts.

Installation notes: before removing the old arm, check the existing linkage geometry and preserve original ball cups and hardware where possible. After fitting, ensure the arm moves freely through its full travel and that it clears cyclic and tail connections throughout collective and cyclic inputs. Avoid overtightening screws to prevent binding.

Tuning role: a degraded or loose wash-out arm alters how cyclic and tail inputs are mixed; replacing it can bring back consistent wash-out behavior and reliable tail authority in hover and maneuvering. Perform gentle hover checks to confirm trim and handling before resuming normal flight.
