YS Engine YSS1015 50ST Propeller Nut for RC Propellers  [YSS1015]

Product outline for prop fastening

This YS Engine propeller nut is supplied as a compact replacement part for RC propeller setups. It provides a dependable clamping point on a shaft or spinner, and is not intended to alter the engine's performance characteristics.

Installation follows common workshop practice: remove any retaining washers, position the propeller, hand-run the nut down the shaft, then complete tightening with the suitable spanner. Take care not to overtighten and verify the propeller spins true after fitting.

Routine care is minimal: visually inspect threads and seating for damage or wear before every outing and re-torque after the initial run when fitted new. Use it as a field or bench spare to speed repairs and assembly tasks.
