The Kyosho 94078 SUS Turn Fin R&L is an aftermarket replacement pair supplied as separate right and left components for use on Jet Stream 600 craft. SUS material is used to improve resistance to corrosion encountered in model boating environments.
Functionally, the set offers stern guidance adjustments and lets modelers fine-tune yaw behavior by changing how water leaves the hull behind the jet. They mount in the factory fin positions and act to modify handling balance without needing major modifications to the hull.
Installation tips: fit each fin in its marked orientation and use the existing mounting points and hardware where possible. Double-check alignment with the centreline and confirm the fins clear the jet outlet at full throttle and during steering travel.
