About this 3D model
This piece will mount on AR44 rear axles to provide a mounting point for weight holders. This will allow you to run weight on the rear axle for a low center of gravity or to balance your RC Crawler (Sportsman, Sporty, Shafty, Pro Comp, etc). Check out this video where I'm setting it up in my Sporty: https://youtu.be/-SnYaSz5ACg
