This GPM Alloy 7075 motor plate is engineered to improve motor mount stability and maintain consistent gear mesh on the TEAM LOSI Micro-B 2WD. It is compatible with Hobbywing 1621 and 1525x1410 motors and allows the use of motor teeth 14T or larger. Note that installation prevents closure of the original gear cover and may require modification of certain battery compartments to achieve correct clearance.
