YS Engine YSF7375 Engine Stay Lower FZ110S  [YSF7375]

Lower stay overview

This is an RC-scale lower engine stay listed as YS Engine YSF7375, intended as a direct spare or hop-up for installations that reference FZ110S in the part name. The component functions as the lower mounting point that secures an FZ110S-design engine to an RC chassis, helping maintain alignment between the engine and drivetrain.

Use this stay when replacing a worn lower mount or when restoring factory mounting geometry during maintenance. The part is described in product materials as a lower stay for FZ110S, so verify fit with your engine mounting holes and the chassis engine bay before final assembly.

Installation notes: fit the stay to the engine and chassis using the original mounting holes, align the engine so the spur and pinion maintain correct mesh, then secure fasteners to recommended chassis torque values. After initial runs, re-check fastener security and alignment as part of routine RC maintenance and tuning.
