Carrera Rear Drivetrains - Profi RC 是 Carrera 品牌旗下為 RC 車輛提供的替換零件。它被列為 Profi RC 系列的後傳動系統元件，並提供 Standard 版本。
Installed this rear drivetrain on my RC buggy and the mesh was spot-on right out of the box. The metal gears feel solid and have handled a few rough runs without any slip.
Dropped my RC car off a curb and stripped the rear gears, so I grabbed this drivetrain as a replacement. It slotted right into the Profi RC setup with no filing or fuss, and the gears run smooth and quiet now. Back to bashing like nothing happened.
Wasn't sure a replacement part would mesh as smoothly as the original, but this drivetrain dropped right in and the gears run quiet with no grinding. Nice to have my RC car tracking straight again instead of chewing through another set.
