RC race enthusiasts, if you're running a Team Losi 22 5.0 platform (like the 22S or 22 buggy/truck) and want to shed some weight and add stiffness, this carbon fiber motor plate is a top-tier upgrade. The part number is TLR332089.
This plate is the piece that holds the brushless motor in its 'laydown' position (where the motor lies flat) in the 3-gear transmission configuration. Swapping the stock plastic or aluminum plate for this one made from carbon fiber has real benefits. Carbon fiber is super strong and rigid, which means less flex under power—this helps transfer more of the motor's punch directly to the drivetrain for better acceleration and consistency. And of course, it's lighter, which helps with overall balance and handling.
It's a direct replacement part designed specifically by Team Losi Racing (TLR) for their competition-level vehicles. Installing it requires some mechanical know-how, as you'll need to remove the old plate and transfer the motor and gears over. Make sure your specific 22 5.0 model uses the 3-gear laydown setup before ordering. This isn't a necessity for casual bashing, but for serious racers looking for every possible edge, a carbon motor plate like this TLR332089 is a popular and effective mod.
