Main Gear Set for RC ERA C189 MD500 RC Helicopter

Restore Silent and Smooth Power Delivery

Stripped or worn main gears are the primary cause of "gear slipping" noises and loss of lift. This replacement set solves power transmission failures caused by crash impacts or long-term wear, restoring the whisper-quiet and efficient drive system that the RC ERA C189 is known for.. Ships worldwide.

Product Highlights

  • Self-Lubricating Material: Molded from high-grade POM (Polyoxymethylene) for low friction and high wear resistance without the need for messy grease.

  • Precision Tooth Profile: Optimized gear mesh reduces noise and ensures 100% power transfer from the brushless motor to the rotor head.

  • Reinforced Hub: Features a thickened center hub to prevent the gear from spinning on the main shaft under high torque.

  • Two-Piece Value Pack: Includes a pair of gears to ensure you have a spare for future maintenance or a full transmission overhaul.

Compatibility

For the RC ERA C189 Brushless RC Helicopter only.

What’s in the Box

  • 2 x Main Drive Gears

Install Tips

  • Gap Adjustment: When installing, ensure there is a tiny amount of "backlash" (play) between the motor pinion and the main gear; too tight will burn the motor, too loose will strip the gear.

  • Shaft Alignment: Ensure the gear is fully seated and the flat spot on the main shaft aligns with the gear's internal D-shape (if applicable).

  • Debris Check: After a crash, always check for tiny plastic shards stuck in the motor pinion before installing the new gear.
