Seesaw Linkage Upgrade for EMBLA SZM2 HI0304112 by Hirobo  [HI0304112]

Rotor Control Seesaw for EMBLA SZM2

The Hirobo seesaw identified as HI0304112 is supplied as a replacement linkage part compatible with EMBLA SZM2 RC helicopters. The note emphasises fitment, installation context, and how the component impacts control input geometry rather than providing extra undocumented claims.

Fit this seesaw to correct control geometry or to renew worn linkage hardware during service. Located in the rotor control train, the seesaw influences cyclic and tail responses based on linkage setup; after installing, confirm control throws, servo centring, and neutral alignment.

When replacing rotor link components on EMBLA SZM2 machines, verify HI0304112 is the correct code for your requirement and perform a full servo and linkage check before returning the model to flight.
