Senc the shop worked on it and tightened the clutch it breaks a lot of axles I put metal ones on but they break the Allen set pins

assuming you're talking about an electric. loosen up the clutch a bit. the slipper clutch is there to take the shock out of the drivetrain. it should have a little bit of noticeable slip when launching from a dead stop on a high traction surface.
