Main Rotor Head Assembly Kit for WLtoys K150 AS350 RC Helicopter

Complete Solution for Rotor Head Damage

Is your helicopter grounded due to a complex rotor head failure or a severe crash? Dealing with multiple bent linkages and cracked blade grips can be a diagnostic nightmare. This complete Rotor Head Assembly for the WLtoys K150 AS350 Squirrel solves the problem in one go. By replacing the entire mechanical heart of the rotor system, you eliminate hidden hairline fractures and mechanical slop, ensuring your brushless 4CH model regains its factory-fresh 6-axis gyro stability and precise control response.  Ships worldwide.

What’s in the Box

• 1 x WLtoys K150 RC Helicopter Rotor Head Assembly

Install Tips

• Main Shaft Fitting: When sliding the assembly onto the main shaft, ensure the alignment pin or screw hole is perfectly centered before tightening to prevent rotational slipping.

• Linkage Connection: Carefully snap the pre-installed linkages onto the swashplate ball links; ensure they move freely without binding through the full range of pitch.

• Blade Tensioning: When remounting your main blades into the grips, ensure the tension is symmetrical across all three blades to maintain proper tracking.

• Safety Inspection: Always perform a low-RPM "spool-up" on the ground after installation to verify that the rotor head spins true without any visible wobbling.

Support & Warranty

• 3-month warranty on manufacturing defects
• Ships worldwide
