On a 1:48 scale scale military helicopter like the RC ERA C170 Longbow Apache, executing violent inverted loops or extreme collective pitch recoveries in 3D stunt mode forces the motor pinion to grind hard against the gear teeth. If your helicopter experiences a rotor blade strike or sudden crash landing while the motor is active, the intense torque will shear, strip, or flatten the plastic gear teeth. Flying with stripped or chipped teeth causes an unmistakable loud screeching noise, massive drops in head speed, slipping under load, and severe motor overheating. Replacing your worn transmission wheel with this factory-original high-density main gear set ensures instantaneous throttle response, smooth mesh tracking, and optimal aerodynamic power efficiency.  \u003cstrong\u003eShips worldwide.\u003c\/strong\u003e\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"12,0,0\"\u003e\u003cb data-path-to-node=\"12,0,0\" data-index-in-node=\"0\"\u003eWear-Resistant Self-Lubricating Polymer Compound:\u003c\/b\u003e Precision-molded from premium high-density nylon resin that handles sustained high temperatures and dampens gear train noise.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"12,1,0\"\u003e\u003cb data-path-to-node=\"12,1,0\" data-index-in-node=\"0\"\u003eReinforced Square Indexing Center Hub Base:\u003c\/b\u003e Molded around an extra-thick square shaft interface slot that prevents the high-torque main shaft from slipping or spinning freely inside the wheel core.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"12,2,0\"\u003e\u003cb data-path-to-node=\"12,2,0\" data-index-in-node=\"0\"\u003eAerodynamic Weight-Reduction Vent Holes:\u003c\/b\u003e Features six symmetrically placed cut-out slots around the gear faceplate to minimize rotational inertia while preserving ultimate structural integrity.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"12,3,0\"\u003e\u003cb data-path-to-node=\"12,3,0\" data-index-in-node=\"0\"\u003eValue-Packed 2-Piece Drivetrain Maintenance Pack:\u003c\/b\u003e Includes 2 complete factory-matching replacement main gears in one set, ensuring you have a backup ready for quick field maintenance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eFor the \u003cstrong\u003eRC ERA C170 1:48 Scale Longbow Apache RC Helicopter\u003c\/strong\u003e only.\u003cbr\u003eFull model page (specs \u0026amp;
