Sceadu SZ-IV Centre Hub Replacement HI0412183 - Hirobo  [HI0412183]

Hub Component Notes

The Hirobo HI0412183 centre hub, listed under part code 0412-183, is supplied as a replacement for the Sceadu SZ-IV rotor head assembly. It acts as the central mounting point where precise alignment influences control authority and flight stability.

Installation notes: examine the mating surfaces and fixings before installation, ensure screws seat correctly, and check rotor clearance throughout its range. Only use thread locking compounds that are compatible with surrounding hardware and maintenance procedures.

Tuning role: the centre hub helps preserve rotor tracking and swashplate geometry; fitting a new hub or making adjustments can affect cyclic responsiveness and neutral trim, so recheck settings after work.
