Cross Servo Arms with Screws for P-40 Warbird RC Fighter 400mm 4CH Plane

Precision Steering for Your Aerobatic Warbird

Stripped servo splines or snapped arms can instantly ground your P-40 Warbird, especially after high-stress aerobatic maneuvers or unexpected collisions. For the 400mm P-40 Fighter, maintaining a precise mechanical link is vital for the 4CH control system to function correctly. These replacement cross servo arms solve the problem of unresponsive control surfaces, ensuring your rudder, elevator, and ailerons move with the crisp accuracy required for loops and rolls.  Ships worldwide.

Product Highlights

• Reinforced Cross Configuration: The four-arm "cross" design provides multiple mounting angles, allowing you to achieve the perfect mechanical leverage for any control surface.

• High-Toughness Composite: Manufactured from resilient white nylon that resists stripped splines while remaining lightweight for micro-RC flight.

• Complete Hardware Set: Each pack includes dedicated mounting screws to ensure the arm remains securely locked to the servo output shaft during high-G flight.

• Optimized for 400mm Series: Precision-molded to fit the specific micro servos used in the P-40 Warbird 4CH series, ensuring a zero-play fit.

What’s in the Box

• 1 x P-40 Warbird RC Fighter Servo Arms Set

Install Tips

• Centering the Servo: Power on your transmitter and plane to center the servo electronically before mounting the arm; this ensures your control surfaces sit neutral.

• Arm Alignment: Press the cross arm onto the servo spline at the angle that best aligns with your pushrod; the cross shape gives you four 90-degree options for the best fit.

• Securing the Screw: Use the included micro screw to lock the arm to the center of the servo shaft; do not over-tighten, as the plastic is designed for a snug, secure fit.

• Linkage Hookup: Connect your Z-bend pushrod to the hole that provides the desired throw; use the outer holes for maximum aerobatic movement or inner holes for smoother flight.
