Seesaw Tail Link Component for Sceadu SZ-IV - HI0412186 Hirobo  [HI0412186]

Replacement seesaw for Sceadu SZ-IV

The HI0412186 seesaw tail link is a replacement component designed for the Hirobo Sceadu SZ-IV lineup, acting as a small lever in the tail mechanism that shapes tail pitch balance and control response. The following notes cover fitment checks, simple installation tips, and how the element factors into trim and tuning work.

Compatibility: Manufactured to match Sceadu SZ-IV models where the original seesaw or lever part is used. Verify the HI0412186 identifier on your existing part so you can be confident of a direct fit.

Installation notes: Inspect the mating pin and surrounding bearing surfaces for damage or wear before fitting. Remove any burrs, ensure full articulation through the entire tail travel, and apply a light oil to steel contact points. Do not overtighten retaining hardware to maintain free movement.

Tuning role: Small geometry changes at this pivot affect tail authority and neutral position. A new seesaw will usually restore original geometry; perform bench trims and small servo adjustments to confirm neutral before flying.

Choose the correct HI0412186 replacement when rebuilding or repairing Sceadu SZ-IV tail linkages; replacing matching components together avoids inconsistent control behavior.
