Racing battery choices

CLICK yes HCR did make arms for the Revo. Perhaps you would be confident with them on and it would at least improve your problem with the threaded part of the ball from coming out. Good aluminum arms in my experience improve hingepin life. Once I put FLM arms on my Maxx hingepins were not a worry. What will break once you install metal arms should be the pivotballs themselves. They should bend or break at the threaded part.
