This is Tamiya TC01 Carbon Battery Holder Set. These carbon battery holders replace the standard plastic parts used on the TC-01 chassis. Compared to the standard parts these parts are minimalistic in design to help reduce weight in the overall machine.
For: Tamiya TC01
Used in place of kit-standard plastic A11 parts, these 3mm thickness carbon fiber components are a rigid and lightweight (3.6g for one set) option.
Removal of a pin is all that is required to release the battery pack.
