Product: Plastic spindle gear kit (5-module) — spare parts set for DIY car model kits Key benefits Wide selection of common gear sizes and sockets in one kit, so you can repair or prototype without searching for individual parts. Compatible with many small electric motors and shafts, reducing fit issues and saving time when assembling or replacing drivetrain components. Lightweight plastic construction that resists corrosion and is suitable for low- to moderate-load hobby applications. Includes axle/socket pieces for easy motor mounting and secure transmission alignment. What the kit contains 26 plastic spindle gears in assorted sizes and colors (as shown in product images). 10 pieces of 2 mm sockets. Gears are 5-module spindle type, intended as spare parts for DIY model builds. Compatibility and function Designed for hollow-shell motors such as 130, 140, 180, 260, 280, and 370. Also compatible with 2 mm round shaft motors and D-shaft gear motors with 3 mm and 4 mm D-axis. Worm gears 662A and 682A are included for propeller drives and specialized transmission slots. Bevel gear(s) provided for right-angle transmission. 2A socket functions as an axle and as a motor fixing socket for stable mounting. Gear model breakdown (included) White gears: 8A, 81A, 81.5A, 82A, 102A, 122A, 132A, 142A, 182A Blue gears: 153AD, 152.3A, 15.317A, 154AD Worm models: 662A, 682A and items listed as 6x62 6 x 8, 6 2A (as shown) Materials and performance Made of durable plastic suitable for hobby and model applications. Best used in low- to medium-torque situations typical of small electric motors and model vehicle drivetrains. Designed for consistent meshing with 5-module gear trains; performs reliably when properly aligned and lubricated. Practical use scenarios Replace worn gears in a hobby RC car gearbox using the matching 5-module gears and motor socket to restore smooth gear engagement. Build or modify a small DIY robot drivetrain using the assortment of spur, bevel and worm gears for direct-drive, right-angle, and propeller-style transmissions. Repair a model boat or drone propeller transmission by installing the included worm gears (662A, 682A) and matching sockets to secure the motor.
