YuXiang F112S Servo Set Metal Gear Digital Servo for AH-1 Cobra RC Helicopter

Fix Swashplate Jitter, Eliminate Servo Gear Stripping, and Restore Sharp Flight Response

A burnt-out, stripped, or jittering swashplate servo on your YuXiang F112S AH-1 Cobra RC Helicopter cripples your ability to control pitch and roll, causing severe swashplate tilting, uncommanded drifting, or complete loss of flight control. Hard impacts during rotor blade strikes frequently strip internal micro-gears or damage coreless motors, rendering GPS stabilization ineffective. Installing generic aftermarket servos often results in plug wire pinout mismatches, incorrect transit speeds, or improper horn geometry. This official YuXiang F112S Servo Set completely restores smooth, high-speed swashplate actuations. Featuring a high-precision digital control circuit, durable internal gears, and a factory pre-wired connector, this drop-in replacement ensures exact centering and rock-solid swashplate control.  Ships worldwide.

Install Tips

• Plugging in & Neutral Centering: Connect the new servo lead into the receiver board, power up the F112S helicopter with the transmitter at neutral (50%) pitch, and allow the servo shaft to center automatically before attaching the arm.

• Mounting Horn & Securing Screw: Press the included servo horn onto the splined output gear shaft as close to a true 90-degree angle as possible, then thread the brass screw firmly into the shaft center.

• Securing Ball Stud & Frame Mounting: Thread the linkage ball stud into the horn, mount the YuXiang F112S Servo Set body into the helicopter frame mounting tabs, and secure the frame screws.

• Pre-Flight Swashplate Range Inspection: Snap the swashplate pushrod onto the ball stud, then cycle the cyclic and collective pitch controls on your remote to ensure full-range movement without mechanical binding.
