This is made from .080" aluminum and this works with Wraith or SCX10 transmissions. This allows you to use an 1/8 scale motor with the transmission. You will need (3) M3X30mm flat head bolts and (3) M3 nylon lock nuts. This is designed to be used with 32p Spur and pinion. If you're using MIPs you'll want to use a 60t spur and a larger pinion to reach the spur.
