Steel Main Shaft Replacement for WLtoys K150  Squirrel RC Helicopter

Eliminate Rotor Vibration

Is your WLtoys K150 experiencing unusual wobbling or losing power efficiency during flight? A bent or worn main shaft is often the hidden cause of severe rotor vibration and poor flight stability. This high-precision steel main shaft is designed specifically for the AS350 Squirrel scale model to solve these performance issues, ensuring your rotor head spins with perfect concentricity for a smooth and quiet flying experience. Ships worldwide.

What’s in the Box

• 1 x WLtoys K150 Steel Main Shaft 

Install Tips

• Main Shaft Alignment: When sliding the shaft through the main frame bearings, ensure there is no vertical play; use shims if necessary to keep the drive gear perfectly meshed.

• Locking Bolt Security: Ensure the bolts passing through the main shaft holes are tightened securely and use a small amount of thread-locker to prevent them from vibrating loose.

• Bearing Inspection: Before installing the new shaft, inspect your main frame bearings for grit or damage; replacing worn bearings alongside the shaft will ensure maximum smoothness.

• Rotor Head Balance: After assembly, spin the rotor manually to check for any tracking issues; a straight main shaft is essential for the 4CH 6-axis gyro to stabilize correctly.

Support & Warranty

• 3-month warranty on manufacturing defects
• Ships worldwide
