Replacement Main Drive Gear for RC ERA C190 Brushless RC Helicopter
Restore Smooth Power Transmission
Stripped or chipped gear teeth are a common result of a "hard" landing where the rotors are blocked while the motor is still spinning. This high-strength main gear solves the problem of slipping drives and loud grinding noises, restoring the quiet and efficient power transfer required for the C190’s high-performance flight. Ships worldwide.
Product Highlights
High-Strength POM Material: Self-lubricating Polyoxymethylene (POM) provides excellent wear resistance and a low coefficient of friction for a quiet drive.
Precision Tooth Profile: Specifically molded to match the brushless motor pinion perfectly, preventing premature gear wear and maximizing torque.
Structural Ribbing: Features a reinforced spoke design that maintains gear roundness even under high rotational stress.
Sacrificial Safety Design: Engineered to strip in a catastrophic crash to protect more expensive components like the brushless motor and ESC.
Gear Mesh Check: After installation, ensure there is a tiny amount of "backlash" (a hair-thin gap) between the motor pinion and the main gear to prevent overheating.
Debris Removal: Thoroughly clean any plastic shards from the motor pinion teeth before installing the new main gear to prevent damaging the new part.
Shaft Pin Security: Ensure the metal pin that locks the gear to the main shaft is fully seated and does not protrude enough to hit the helicopter's servos.
