Metal output gear?

[A RC Dude]

thanks guys, thankfully i had a spare so it was a quick fix. i limited the ESC to 75% throttle for a run and it still had slightly more power than what's really needed in that thing, i can barly reach full throttle as is and i has one of my tires blow out on me lol
so i think for now i'll stick to stock but it'll deffinatly keep that in mind for when i happens again.
thanks for the information :)
