Mobster

Recently i installed the tekin rs pro and 13.5t redline combo in my axial wraith. I ran 3s for the first time the other day and it was fun and fast for several minutes before it stopped shut down and started due to thermal overload( I think it was a thermal shutdown?). So I put the 2s back in and noticed that the servo seemed slower and weaker.
Did I fry my servo? I thought that the RS pro was capable of doing this
