Hirobo HI0304115 Rotorhead Stabilizer Bar for Embla SZM2 L=220  [HI0304115]

Embla SZM2 balance bar — product details

This stabilizer bar is offered as a direct replacement for the Embla SZM2 rotorhead family. The L=220 callout denotes the effective length used in the rotorhead linkage layout.

Functionally the bar tempers cyclic inputs and promotes smoother transitions between control states. Installed on an Embla SZM2 head it changes the neutral characteristics and affects how quickly corrections propagate through the rotorhead.

Installation on standard Embla SZM2 configurations is simple: remove the existing stabilizer and install the HI0304115 using the original mounting points. Make sure linkages are free, ball links and linkage cups are secured, and that the bar moves without interference.

Tuning guidance: keep factory linkage lengths as your baseline, then adjust incrementally and test hover and low-speed manoeuvres after each change. Small link shifts can noticeably alter cyclic authority and stability, so document adjustments to return to known setups.
