XLPower Nimbus 550 Nitro Engine Shaft Set V2

Description

A new design for higher precision and reliability, fully compatible with OS and YS engines.

Key Improvements
• Improved concentricity — upper clutch bearing alignment significantly enhanced for smoother transmission.
• More reliable structure — starter coupling no longer sits inside the bearing, reducing clutch loosening risk.
• Optimized taper angle — easier installation, secure engagement without excessive tightening.
• Universal fit — compatible with both OS and YS engines, no modifications required.
• Recommended tightening torque: 16–18 Nm for secure and reliable locking.

👉 Engineered for maximum precision and durability in 550-class Nitro systems.
